It's another day at SMA with the Chevrolets folks. We got the 2011 Uh GMC Over there it's ,500 It's got the Big 53 Money lights on uh McCoy and I are going to have a look at it and see what we're going to have to do. All right Here we go. Somebody must have cleared the codes cuz oh gosh dang it idiot.
There was no codes and anything else. Uh, there was just an the ECM there. So let's just see Evap codes on Chevy. Imagine that.
Uh, we got your classic 446 vent system performance meal requested. So that's turning the light on. Fuel tank pressure sensor circuit low that's got the light coming on and your classic 455 large leak and this one has the mill requested. Uh, so all of these will typically be related.
Uh, particularly this one here. Fuel tank sensor circuit low. If it can't see fuel tank pressure, it can't tell if the vent is working. It certainly can't detect a large leak.
Um, let's go right in and just look at some data. We'll go to the engine controller and then we'll go live data. We'll go evaporative emissions and we'll look at the fuel tank pressure sensor pretty faure prone item on a General Motors And there we are. 08 volts.
that's not how they typically break and then it shows the tank pressure at 11.8 mm of mercury. whatever that is. But uh, this is the first thing we need to fix before we can identify leaks or anything. Uh, that's not true because we could, uh, turn off the canister vent valve, do a smoke test on and stuff.
But let's have a look at uh that fuel tank pressure sensor circuit first. Um, we see that it's low. so your normal uh General Motors fuel tank pressure sensors run at 1 and 1 12 volts 1.4 to like 1.6 atmospheric pressure. Uh I believe the open circuit voltage on this just unplugging the sensor.
it does go to 5 volts and then um, when it's shorted, you know goes to, you know, goes to ground. So we could be dealing with a sensor that's internally funky. Um, we could be dealing one. uh that has, you know, a short to ground, you know, wires pinched or something.
uh something like that. Sobody put a fuel pump in it. You know? Who knows. So let's get up in here I Think we should be able to reach this without dropping the tank or pulling the drive shaft and see if we can't get it unplugged and just see what it does.
Uh, right here on on scan data. if we unplug it, it goes to 5 volts. We'll good. Oh there we go.
Whack my head, make sure the frame's not super rotted. oh just a little bit. Any Ro holes over here. oh sorry, oh it get you in the face that te you.
Oh yeah, she's rotted out good. It's got your classic rotted frame so it'll fail inspection obviously. but for the sake of the video, we'll uh see what we can do. So our fuel tank pressure center lives up here.
I'm going to see if I can reach up there and get it unplugged. Uh, we won't spend a lot of time on it cuz this truck's going to go to the crusher. Um, but we'll at least finish off the video here so everybody knows what was wrong with it. Let see if we can reach this little guy. we just kind of do by feel. So I thought feel the fuel pump plug I think we got her this time. folks. there we go.
goes to zero. Oh, it goes to zero. Oh okay, see I thought these had an open circuit voltage of five but have open circuit voltage of zero Z Okay so our connector out here. uh, some of you folks May wonder why we're We're still going at it even though the frames rotted out and I said it won't pass inspection.
Uh, when I say that I mean it won't pass inspection in my shop? Uh, it'll pass inspection in other shops. We'll say um, and is the frame repairable? Probably. Uh I don't do frame repairs here. Uh, but he certainly can go somewhere and have them put.
you know, some spray foam and uh, some spray paint and stuff on it. But uh, it needs the engine light out. No matter, even if you go to a lickum stickum shop. So let's uh, keep on keeping on.
Hopefully that answers the question. Let's get a meter, see if this has uh, five volts ground, and see if the Uh signal works and then make the call on what we're going to need. McCoy's getting the stuff around. Uh, getting us a meter and everything.
I'm going to grab a wiring diagram. Uh, even though we can figure it out without it. Uh, when when somebody's just learning, uh, it's a lot easier. Uh, when we when we go like this.
So we're going to find the fuel tank pressure sensor and it happens to be right here on this diagram. Um, so what we're going to do is we we need to make sure that our our ground is good, our power is good, and our signal wire is good. So first thing we're going to do is we're just going to use our meter. Uh, we're just going to go to Digital Meter Volts DC We like to use this one because the screen's bigger.
It's easier to see on the YouTube Uh, we've got a 0 to 20 volt scale and we're going to probe across the power in the ground and we expect to see 5 volts. Uh, we're going with the gray. Gray is going to be the power side and the tan with black is going to be the ground. so he's going to identify the wire colors on it.
Hopefully they match What was it gray and what? Yep, gray. and then the tan with black. They should be right next to each other. Pin two and pin three.
and then we've got some uh, front probes on there. He very gingerly going to front probe it. So we expected 5 volts and we have 5 volts So that tells us our our power and our ground back here is good. Uh, we're going to take and check the signal wire now and that's a little bit more tricky.
So right now it looks like we we likely have a bad sensor but we need to know for sure. So what we're going to do is use your uh humble test light here incandescent test light. And because we're going to stick power on the dark green wire because we need to see on scan data. So if if we stick you know 5 volts on our dark green wire, we should be able to go back in The scan data and this display should display 5 volt. Uh, theoretically cuz this is looking at a fuel tank pressure sensor wire. It's the only wire it's looking at. It's not looking at the power of the ground, it's just looking. What's how many volts are on that fuel tank pressure sensor wire? In order to do that, we have to jump power to it.
but we have a potential. is that shorted the ground? Now if we take that 5 volts and we jump the 5 volts directly to it with uh, you know, just a jump lead and that um, sensor wire is shorted, you potentially could let the smoke out of the ECM. They usually have a level of protection that doesn't allow them to do that. Usually you can short a 5vt reference line without any damage.
But to be on the safe side, we're going to do it through a test slate. Uh, worst case scenario: if that 5 volts or if this signal wire is shorted and we jump 5 volts to it, what's the worst thing that could happen, You know. McCoy The light lights. The Light lights.
That's the worst thing that could happen. And five volts. It's not going to light very, very much. Uh, it's not going to light very bright.
So uh. McCoy knows and understands that because he's been watching Scanner Danner's uh, Basic Electrical In or Basic Electrical review on his premium channel and that's why you know. Paul Danner is also a big fan of the test slate. Worst case scenario: the light lights.
So McCoy is going to stick one of those leads in the power in the other one in the signal wire. plug your test light right In the end of that, go, we'll pop back. and there we are. We're at 5 volt.
So what's that? Tell us? Well, that tells us our circuit is intact. Uh, go ahead and remove your test light McCoy and that should drop right back to zero. And it does. so.
Open circuit voltage is zero. We have good power, good ground and we know that the wire running all the way to the computer is good. and we also know that the computer is good. It can interpret the 5V signal so what's that mean means it has a bad fuel tank pressure sensor.
Just like the code said, we could have just read the code shotgun the part. uh, you could have and in this case you would have been right. Uh, this is how you test most three wire sensors uh that operate like this. You know most three wire pressure transducers will say you know they've got power ground signal.
You need to make sure that the power power on ground is good and make sure that the signal wire run into the PCM is good and in this case they are. So hopefully you guys understood that. I'm going to get a hold of the customer I'm going to finish looking the truck over. I mean I See, it's got tires are wor down of the wear bars and stuff so he's got some other things. Uh, but I'll get his thoughts on. you know, the rusted out frame and if he wants that fixed for the engine light and then uh, we'll be right back and I'll let you know what's up. We're in luck folks. Guy wants to fix it.
We got a new one here. Standard Motor Product Trust Standard It says when OE fails. Uh, here's our old one McCoy and I were able to reach up there and get that out with a little teamwork. We're going to get this one uh, lubed up here on the O-ring get that slipped in plugged in and then we're going to look at our scan data.
We should see like I say 1.4 to 1.6 is what I expect and then we're going to check to make sure the rest of the EVAP system functions as it should. Our new sensors in keys on We're see uh 1.3 which is a little bit lower than what I would expect, but it is an aftermarket sensor. We are at 8 mm of mercury which translates to4 in of water which translates to 0.014 psi. So almost atmospheric pressure.
What we want to do now is we're going to go into our active tests. We're going to go to Vent Solenoid and we want to make sure the vent solenoid works okay. We heard it click. It's warm in the shop, so this should start building pressure relatively quickly I would assume.
Um, yep so we can see here we're building pressure. Fuel's volatile, we have the system completely blocked off, purge valve is closed, canister vent valve is closed and we should start building uh, pressure and we can see our pressure is starting to go up and then if we put it back to atmospheric or open the valve, it should go back to atmospheric pressure. And it did it. went back to, you know, 1.31 Uh, these are pretty fault tolerant.
The EVAP systems I don't think we're going to throw a code being at 1.3 like I say usually they're 1.4 to 1.6 somewhere in there. Ideally it would be one and a half. Uh, but and I've seen aftermarket sensors you know, skewed like this. Uh, nothing to do with the wiring.
We could get another sensor, put another sensor in and you know we're going to have you know a different reading. But we can see that the system is sealed, does seal, and can build pressure. Open the system back up. Now we're going to check.
We're going to let the car down. We're going to throw a hose on it, start it up, make sure that the purge valve works. We're going to do a purge and seal. Um I don't know if that's in in here.
Oh yep, it is. So there's a puron seal where we're going to put a a vacuum on the tank and then see if it can hold vacuum. Of course it'll Decay Uh, a little bit over time. so we're going to set it down and do that test next contact.
All right. we got it running H Okay, uh so right now it's vening so we're going to turn on the purge valve. so we got it at 2% says it's not bending right now. we need to get the tank pressure.
Okay, we're going to let it build a little bit of negative pressure here. only I got running at 10% if we Crank It Up tooo fast so suck the sides in on the tank. we'll let it get up to about 2 and 1/2 volts is all right. and then we're going to seal the system off. Purge valve is at zero. We are not venting so purge valve is closed. Vent valve is closed and you can see we're holding vacuum. Now there's going to be a certain rate of Decay Um, because the fuel's Valal and it's building pressure.
Uh, just like we shown before. but if we had a gross leak, this would drop down rapidly. You know we'd go from 2 and a half as soon as we sealed the system. it would drop right back to the the 1.3 but we can see that we're we're holding vacuum in the tank so we don't.
The large leak code is irrelevant I guess is what I was trying to prove with uh with this test here actually holds vacuum quite well. All right, So that's that's that folks. We're done here here. One thing we do want to do, we're going to pop back into generic OBD2 data.
We're going to see if the drive cycle is finished. We should have checked this prior to doing anything. That way we don't get any surprises. Okay, so the drive cycle is finished, and the only codes it had are the codes that uh that we saw there in the beginning the canister vent valve performance yeah, vent control circuit they call it on this side but it's not a not a circuit code, it was a performance code large leak and then the pressure sensor a so pending permanent and current.
So this what we just fixed should clear up all of this codes. There you go Ahad and shut it off McCoy That's it folks. fixing the EVAP on your GMC or Chevrolet Uh, it's very similar on the trucks as it is on the cars and it is on most of the general motor systems. They run a classic vent Purge type system for lack of a better term purge valve vent valve pressure sensor uh all three big components uh on the system and usually you can diagnose mostly EVAP system right from the scan tool.
Uh, if you understand Steing operation, the Go Te garage NGK Wells EV whatever you want to call it. uh over there on their YouTube channel Mike Becker Uh does a great job and has a good video series on Uh Evap systems. I think he breaks them down per brand General Motors Chrysler the Toyota stuff Intrusive, non intrusive. all the different types of evap system so you can go check them out hopefully.
My video was helpful trying to help McCoy along and his um Journey discovering if he wants to work on cars or not I suppose so I get a little fumbly cuz I have to remind myself of how things work and why we're doing what we're doing so it's a good reminder anyhow. Questions, comments, concerns the inty Facebook you guys knowwhere to find us and just remember viewers. If I can do it, you can do it. Thanks for watching He.
I liked the intro, "ITS ANOTHER DAY WITH SMA"….Your new slogan, LoL….Great video as always, thanks for sharing
👍
I’m very curious, when discussing open circuit voltage… how is the ECM measuring open circuit voltage? If open circuit voltage is 5v, I would guess that would mean the ECM would be measuring the difference in voltage on the reference wire and the signal wire? And in this case, since open circuit voltage reads zero, it must be measuring the voltage difference between signal and ground, which is zero? Am I thinking about this the right way?
You'll make more money as a dentist or proctologist.
Great to see you working with young blood! Anyone who is showing the interest to learn from Scanner Danner is a good sign. Keep up the good work!
Man I do not miss living up on L.I. and seeing 12 year old vehicles that fail safety and head to the crusher for parts only. He'll get 5-6 more years with some expandafoam and rino lining paint. haha
Been a run on EVAP codes lately it seems. Jeep, Hyundai, Ford, Toyota, GM…Job Security light pops on every one of em.
Just let your apprentice know at the end of his time with you that the automotive repair industry is not for the faint of heart. If the flat rate system doesn't get him the tool truck will empty his wallet quick enough. It can definitely be a thankless job at times – faulty aftermarket parts, customers complaining about issues you did not cause, bosses that want you to move faster, shop politics, standing for long periods of time, costly mistakes starting out…
Are there actually shops that specialize in fixing rotted/rusted out vehicle frames?
That kid is so lucky to have someone like you to teach him
😥 Some day you are going to retire and the world will be a less good place…
You remind me of the show "House". The patient is dead but he solved the mystery. 😁
Prefer your content when it's just you working on the cars…….
As a sparky, I enjoy training apprentices, as long as they're willing to work and learn. Your boy McCoy seems to be absorbing the information… I learned, largely self taught from Haynes manuals, and trial and error, on older cars, with a lot less computers and scanners. Colour tune and timing lights, normal test equipment, meters and test lights, were pretty much all I needed. I guess, what I'm trying to say, is there's a lot to learn in car diagnosis and repair these days. There's a lot of expensive diagnostic equipment you need to do the job, unless you're a parts cannon moron, with more money than sense (for a DIY guy). Sadly, a lot of shops give your trade a bad name, using that tactic too… It's the same in most, if not all, trades. There's some shocking sparks out there. Teaching an apprentice how to use the tools of the trade, and how to solve the puzzles presented, step by step, is the right thing to do, and like you said, helps the ol' brain to retain the information yourself too. Keep up the good work.
Dr. McCoy in no time
Good on you Eric for helping McCoy. Thats the greater good here i think. Thank gosh darn i dont live in new york with my Chevy trucks,…I'd be doomed!
Spray foam! I spit out my coffee!
Eric, can you please tell me what your go to scanner is. The one you prefer. I bought a cheaper one. A toolx 7. It paid for itself the first week. Im sold on them now. I want one with the Christmas tree for a quicker diagnosis. Mine does not have it. An audi takes 20 mins for a total scan. Thanks sir.
What's a good website to get free download mechanic specs and mechanical maintenance for a 2009 Hyundai Tucson V6 2.7 4 * 4
Eric you are a great teacher. Thank you for teaching me a lot. Keep up the great work. McCoy has a great teacher. 👍👍
Gravy! 😊
Beautiful videos matey,ILove Watching Scanner Danner To,GoodOnyarz felarzs,no joke very much enjoy your videos mate!
Lucky Kid. If you wanted to learn about car mechanics. And all that modern crap. You could do a lot worse than train with you. I would be hopeless these days. There would be broken bits of plastic everywhere. And busted connector blocks. I will stick to the old stuff. Spanners and a hammer.
Who is McCoy ? Illegal alien from Mexico.
Being that every sticker has station identification on it, why in the thunder doesn't DOT do crap about OBVIOUS BS STICKERS? LAZY ASSHOLES… THAT'S WHY!
Even if Mccoy doesn't decide to go into the trade, learning basic diag skills, trouble shooting skills can apply to many many jobs. And, being able to fix your own car is also great knowledge
How amazing is it that McCoy gets to learn from a great mechanic that does things the correct way, and is an amazing diag guy!
Hmmm so me thinks I have a bad sensor too I had bad wires too that ripped off I fixed that just now and I did this test too you can ohm resist test the ground too you'll have a high number but that's because the computer. I did that too with the test light and I did get the volts through the scanner too. I saw it too is there a way to actually see if the sensor is capable of working with the volt meter? Like if I probe the signal and ground am I able to see something? Or do I really need voltage, ground and the sense wires like a TPS. If that's the case because it uses the same set up I'd imagine I do.
I thought Click and Clack were smart…those MIT bros got nothin on Mr. O!
What is the model number of the scanner you used here from autel
Is he the REAL McCoy?
Based on a previous video by Eric and some others I asked my mechanic to check voltage on my s10 sensor because I had p0446. It was hovering in 4.86 range. I decided to lift my box to check condition and rust paint underneath and replaced sensor with oem. Was able to back probe and confirm 1.5 v. P0446 is history.
Looks like this truck has a serious case of EVAParanoia!
Keep Andy away from McCoyote, seems like a good kid..
Some years ago in Ontario the
drive cleanprogram was created. This meant cars had to be assessed every couple of years. Participating garages would run your car on rollers and measure various pollutants like NO, CO … this involved a big investment for shops and a pain in the neck for drivers needing to make appointments. Eventually this approach was abandoned as the province realized that ODB systems were plenty good at monitoring defects. Now no inspections unless the title to the car changes. In that case a thorough go over is needed – everything related to clean running and safety. Holes anywhere in the body or frame or suspension is a fail. Still wonder what the shops did with all those service bays filled up with a dyno?It’s a very good thing that McCoy is NOT getting his exposure to mechanics at a “Lick ‘em and Stick ‘em” shop
I saw the title and thought “JAROC” (just another rusted out Chevy) so I watched it in 2X speed!
Glad to see you are teaching someone the trade
Always enjoy electrical diags especially when your teaching someone in you shop
I have always found that knowledge is re-enforced in my own brain when I give it to someone else. Draw a 3 inch tall equilateral triangle. Draw two lines – 1 inch down crossing perpendicular to the center line of the triangle and 2 inches, (these lines should be parallel to the base). You now have 3 sections that have different volumes. Top to bottom 1, 2 and 3. Section 1 is the amount of knowledge a person gains by reading about 'changing a tire'. Section 2 is the amount of knowledge gained by seeing someone 'change a tire'. Section 3 is the amount of knowledge gained by 'changing a tire yourself'. Hopefully your 'knowledge triangle' will only grow larger as you age.
What is put on the roads in up state NY can't be just regular road mix must be different from Wisconsin
Another fine diag and fix.
for a 2011 its not that rusted
I think the car companies need to start testing their vehicles in Avoca NY because it has to be one of the most aggressive environments on a vehicle. That truck should be rolling down to Wilberts.
I also had P0446 on my 05’ GMC Sierra with the medium 4.8L and extremely low mileage. It was the fuel tank psi sensor and was able to reach in the wheel well over the frame rail with the wheel removed without dropping the tank and swap the sensor out and that fixed the problem. But before I did that removed the vent valve believing it was that just to find no issues applying voltage to the connector and the old breath test. That taught me like this good video that one code can set another code and once you fix the problem all the codes magically will disappear.
Don’t crush it. Take it to Ohio and sell it. No yearly inspection. They drive freaking everything.
2007-2013: THE BIGGEST PIECES OF CRAP EVER MADE BY GMC were made during these years,
Eric, please promise us if you ever do decide to go into teaching at a school you'll bring us along by recording the lessons? I am so envious of that lad!
Why repair a vehicle you know that shouldn't be on the road? Just a question, I've always wanted to know. I love watching you diagnose problems and how your brain works. Huge fan from Canada 🇨🇦
Baseball, Hot Dogs, Apple Pie, and SMA!!! 😁
good job McCoy you fixed another one
Now that's how you do a great video!.full explanation of what your doing and what to expect. Always great stuff from SMA.
Eric thinks anything with rust belongs in the crusher lol
I thought you got snow in the PRNY. How does that Chevy handle with those bald tires.
Awesome great video!
Nice job taking McCoy under your very capable “wing”. Question; do they even sell Fords in central NY? 😂
Hey Eric, where’s Josh ?
Spray foam and spray paint. Who knew body work could be this simple! LOL.
…and believe it also translates to 2.5 CuYds of concrete. 😂😅😂😅😂
As someone who also lives in the salt belt, I just don't get it. These newer trucks have such high GVW and tow ratings yet the frames rot through after just a few years!
My 1977 GMC C-25 has been a rust belt truck since new. I bought it in 1984. Since then, I've done the typical body work three times and rebuilt the engine/transmission twice. However, the chassis is still rock solid.
I also have a 2006 F-250 Ex-cab 4×4 (another salt belt truck).That one will be getting body work when the weather breaks but, it doesn't need any drivetrain work. I just bought the Super Duty in September and before I even started the engine, I crawled underneath to check the frame. It's still solid too but, the truck has under 130K miles so, it wasn't used that much.
I don't baby them either, my trucks earn their keep but, I DO keep them as clean as possible.
Every time I see a newer truck, no matter what brand, with its rockers and cab corners gone and bed sides flapping around while pulling a trailer down the road, I always wonder if the frame is going to break in half while I'm next to it!
Pressing a lot more buttons these days – where's the wrenching? Sign of the times. 😀
It's too bad you don't get into undercoating in another building , your area really needs one , you might as well make some money on that business
Always good to have an SMA video waiting to be watched right after dinner…..Coney with mustard and onions, chips, and a coke btw.
So disappointed by Eric on this one. Might have to unsubscribe. I can't believe he's sending this vehicle with a rotten frame down the road when a few drops of JB Weld would make everything ok.
McCoy run into and Hadfield's lately?
But how do I know that guy is the real McCoy? Sorry, couldn't resist….
Nice helper!
Question: Would undercoating ( since no one in New York seems to believe in it) have prevented this failure?
My concern is that you are getting so old that it might be getting too close to retirement age and we wont be getting your videos much longer!!!! Maybe you can have Josh do the physical work and you film it from your wheel chair??!!
EVAP issues on a GM vehicle, surely not.
I wanna go to SMA mechanic school that would be awesome 🙂 how much per semester ?
Thank you for another great video. Stay safe out there. Cheers
Eric, those frames can be legitimately plated without cheating. Mustie 1 in New Hampshire has done it with no issues. He only works on his own vehicles so liability is not a factor. So far he hasn't had a fail. Just sayin'!
I used to live in the rust belt (Buffalo), and had a 10 year old Ford Galaxy .. it had a bottomless trunk, with an aerodynamic (flying) fuel tank. It didn’t pass inspection .. it was still running, and driven to the junk yard.😮
EVAP codes. The steel, evaporating (actually oxidizing), with salt and H2O as catalysts.
Just rolled in 😂😂😂
Just put some black tape over the light on the dash. Next!
Excellent videos Eric. I'm learning to stay away from all Chevrolets and GMCs, as well as Fords. You may not have time and that's OK, but can you help me with a 2015 Toyota Tundra EVAP issue. Seems that Toyota's don't have many EVAP issues that I have seen. I am having difficulty finding the location of the actual fuel tank pressure sensor on a 2015 Toyota Tunda 5.7L. Where is it actually located? On the fuel pump, in the EVAP canister, or where? Can you help to determine its location? Once I know where it is, I might can diagnose the problem. P0453 is the only code displayed on my ODBII scanner. No one has made a video on this era of Tundra.
I like the way you are training McCoy.
McCoy, How are you managing to not call him Bones 🤣
McCoy is getting the best hands on Ed from a absolute master
South Main Auto.. That you man is getting taught by one the best. Just like I was taught many many years ago. That's why I always try to help/teach the new guys when they need help. Us old school guys should always be willing to teach our knowledge to others because when we die off the knowledge does too.
Unbelievable planned obsolescence….just ridiculous how they stick it to the working man…good for your shop…but seriously? They start rotting the minute they hit the NE streets without protection or preventive maintence!!! Woolwax, FF, bar and chain oil , used motor oil, MMO is cheap….chinese chevys are not!!! Friggin shame!
The full circle. Just as Eric was taught by a master when he was young, McCoy is being taught by Eric, the new master.
Good for you to take on an apprentice and get things moving along with the kind of good people we got coming into the automotive industry.
I've had 4 apprentices and it's a good feeling to give each Apprentice a future they can fall back on. Your a great Teacher, with a patient temperament. All the best from Surrey BC Canada
That intern has no idea the gift he’s been given being able to come in green and be taught by one of the greatest mechanics alive.
I’m a full time tech for the last decade and in the last 4-5 years watching all of your videos I’ve come so far and improved drastically. Watching your ways and implementing your methods into my day to day life has done a lot for me.
You’re electrical diag 👌🏿👌🏿👌🏿
Seeing how your brain works in thinking about a feasible process is top notch. I’m lucky enough to still posses the drive and desire to continue learning unlike so many others in our trade.
I’ve learned more in the last 4 years from you then I had working under journeymen while doing my 4 year apprenticeship.
You keep up the amazing work man!
Hope McCoy appreciates what a great teacher he has. He will be way ahead of most techs when you are finished with him.
I feel like I'm watching old Star Trek episodes when you reference to McCoy. Doctor in training.
I guess once McCoy advances and graduates you'll start calling him Bones. LOL.
Glad to see McCoy participating. Never know, he may have his own channel someday.
You having an apprentice on hand also makes for better YouTube videos for some of us. The explanations are a little more detailed ,and so clearer to the untrained viewer interested in learning.
Spray foam not a chance
I like that you have McCoy around, if only that you're keeping things simple for the rest of us.
Always educational following the process.
No corners cut. Well done again, sir!
Tanks Meson! (local lingo) Luv your videos! Makes me a better Technician, watching since 5 years! Hello from Ingonish beach Cape Breton!
McCoy has the hands that should be playing a piano or a violin. 😁
What do you think about a 3.5 in a transit van would you have one stay away from it I would love your opinion
Why ain’t this young man watching your videos? Shame on you McCoy! JK 😂 you are very privileged to work along side with Eric
One of the best teachers out there
What I would give to have a day in the life
Hey Eric do you know if this process can be done the same on a Honda evap system to check for leaks?
I've noticed that on certain faults such as evap codes on GM that after repair and confirmed to do not clear codes and the reset will be a lot faster
