    Things happen?!?! LMAO!!!

    Heatercore video needed!

  3. Avataaar/Circle Created with python_avatars Space Kissingher says:

    That tool is probably better then me using a small hose trash pump to run evaporust through the system for week.

  4. Avataaar/Circle Created with python_avatars Jason Thang says:

    Flushing out the crusty old dexcool this fix will last.

  5. Avataaar/Circle Created with python_avatars ksmith says:

    I guess the old 180 degree thermostats are no longer used.

  6. Avataaar/Circle Created with python_avatars K S says:

    alot of people dumped the dex-cool out of the 3800 series engines because the dex-cool would eat through the gasket for the intake manifold and if you're stuck in the middle of upstate Montana your roadside gas station probably doesn't stock dex-cool and dex-cool and con green can't be mixed

  7. Avataaar/Circle Created with python_avatars oned4metwo says:

    That was super helpful as I have a '99 Riviera. Now, how do you get the passenger door open? LOL

  8. Avataaar/Circle Created with python_avatars ` says:

    HEY! It's that guy! Thanks for that. Always a good time hearing it.

  9. Avataaar/Circle Created with python_avatars geofjones9 says:

    Didn't see you flush out the engine with water & air- both directions. As long as your flushing, Make sure you get the whole load! Otherwise very thorough.

  10. Avataaar/Circle Created with python_avatars Randall Riggs says:

    Thanks Eric for all that you do. I didnt know the tricks of flushing the radiator,but thank you. Thanks for taking care of the customer,and you always do a good job!

  11. Avataaar/Circle Created with python_avatars Wayman Simmang says:

    Thanks. For being honest

  12. Avataaar/Circle Created with python_avatars chipset 5280 says:

    I have a shameful confession: I want to blow out a heater core to see if crud comes out. LOL Alas, I'm just a computer geek and not allowed under the hood for any reason. 😑
    That said, Eric, I absolutely LOVE your channel and enjoy watching a professional do his thing.

  13. Avataaar/Circle Created with python_avatars Peet Ky says:

    good content

  14. Avataaar/Circle Created with python_avatars Gbigdog84 says:

    Was wondering if you ever use airlift coolant tool? Whats your opinion on it good or bad

  15. Avataaar/Circle Created with python_avatars Pontificus Vascillious says:

    i'm sure this is similar to what Jiffy Lube offers for it's 'coolant flush' …🤨

    Question, what does PRNY stand for Mr. O.? I’ve tried lookin it up but it’s been buggin a fella for months

  21. Avataaar/Circle Created with python_avatars Henry Bucki says:

    love your down to earth way of talking to us. even though you are a yankee

  22. Avataaar/Circle Created with python_avatars Robert Shannon says:

    Great job on the coolant and changing out the thermostat. Remember if we can’t do it you can ! Lol 😂

  23. Avataaar/Circle Created with python_avatars 44R0Ndin says:

    Appreciate the approach on the why you flush a heater core vs why you replace it, especially when it's a Buick.
    Buick just can't shake the "old people's car" label, no matter how much they spend on fancy commercials with young people having fun in them and people amazed that it's a Buick.
    And with that, comes the need to think of how long your repair job has to last, and how much the person can afford to put into a fix.
    Lots of these older people are on fixed incomes after all, they can't just drop… usually around $1000 on a heater core replacement after you include labor costs.
    So being able to get this thing working again with just a heater core flush and cleaning out the squirrel cage blower wheel is a gigantic savings for the customer, and if something else more major goes wrong with the vehicle, chances are they'll remember you saved them money in the past and come to you for help.
    One of those "earn less now to earn more later" kind of things, if you get what I'm trying to say. If you don't hit the customer with a sticker shock every time they visit you, they'll probably bring it to you for more minor stuff more often.
    Stop thinking of the up-sell, and think of the future-sell instead.

    I miss my '95 Buick Ultra supercharged. Almost as much as my mechanic does…..

  25. Avataaar/Circle Created with python_avatars paulparoma says:

    GM did a great job designing the engine bay on these cars. Everything is logically laid out and within easy reach. Nothing like the overstuffed engine bays on modern cars.

  26. Avataaar/Circle Created with python_avatars David Robins says:

    I thought I heard something about the age of Buick drivers in there somewhere. I laughed right out loud. (Oh, it's LOL now for those younger people.)

  27. Avataaar/Circle Created with python_avatars Mark Evans says:

    27 years as a mechanic and I gotta say those 3.8 L motors are the best most reliable engines GM ever made! Lots of power also!

  28. Avataaar/Circle Created with python_avatars Jeffry Blackmon says:

    50+ years ago I worked in a radiator shop, removing/installing radiators and heater cores. Now and then we'd get a car that needed an engine flush. They were amazing as the water would come out completely black. After several blasts it looked much clearer.

  29. Avataaar/Circle Created with python_avatars Nuggets MT07 says:

    A wet and dry vac works well to pull old coolant out of the block .etc

  30. Avataaar/Circle Created with python_avatars Matteo Pasqualetto says:

    Aren't you going over a little overboard just the flesh out of heater core a job that probably cost $60 is costing the guy by 400 now

  31. Avataaar/Circle Created with python_avatars 1320Jay says:

    What is this…Vice Grip Garage??

  32. Avataaar/Circle Created with python_avatars Know One says:

    Great job on old iron….LOL

  33. Avataaar/Circle Created with python_avatars Neil says:

    Great Job and great video! I like that you treat your customers cars as if they are your own. If a flush works and…If it ain't broke, don't fix it!

  34. Avataaar/Circle Created with python_avatars Eric Muller says:

    where do you get that flushing gun thinghy?

  35. Avataaar/Circle Created with python_avatars Steve Banda says:

    You do not have a vacuum coolant refiller?

  36. Avataaar/Circle Created with python_avatars Troy Belding says:

    I've always done my coolant flushes by:

    Pop the upper radiator hose, run it to a bucket.
    Drain the radiator itself to a pan, cork it.
    Drain the overflow tank.
    Fill radiator with distilled water.
    Open heater fully.
    Run engine until the thermostatic relief valve (what they keep calling a 'thermostat') opens.
    Keep adding distilled water until the water into the bucket runs clear.
    Cut off engine.
    Drain radiator and cork, add coolant concentrate until you hit the 50/50 point for the car. If you can't add enough, start the engine, drain out a bit more distilled until you have concentrate right.
    Reconnect all hoses.
    Fill overflow with 50/50.
    Start engine.
    Keep adding 50/50 to radiator as it refills the upper hose. It doesn't have to be perfect. As long as it's at least 40% coolant, you're good. If you hit 60% coolant, you're still okay. You can do a drain and fill after a year with 50/50 mix. If you keep up with drain and fills, you'll keep your fluid fresh.

    Caveat: Some systems now are built where you HAVE to use a machine to drain and fill. (Ford trucks). Others, like the Mazda 5, have the drain hose _partway down the side of the radiator_. You'll need to cork that so that what you pour into the radiator cap doesn't come straight out. (if you have a new hose you're going to install anyway, just cut the hose in the middle, one side to pinch off, the other to be connected to go to the bucket)

    You will go through a lot of distilled water, but it's not like you're going to do this monthly, or even yearly. This should be an every three years type thing.

    You can do the flush with distilled and premix. Do the same thing as the distilled, except keep pouring in the premix until the water coming out isn't clear. (Or you can use the premix in place of the distilled water, but that's a bit more expensive than using distilled to make sure everything flushes out clear)

    Question: Do you get more credit if I let the advertisements run completely ? Because I can watch them for a good cause. Steve

  38. Avataaar/Circle Created with python_avatars adam0U812 Davies says:

    Wondering if anyone else puts dielectric grease on hose's to prevent them sticking to the housing on the thermostat and other nipples ?

  39. Avataaar/Circle Created with python_avatars Problem Solved says:

    Eric, you da man!! Love your videos. You’re so honest and tell it like it is.

  40. Avataaar/Circle Created with python_avatars fire surfer says:

    I need to flush my house. I have to wait until springtime. $2200 later, It's good enough for now. The plumber got the heat up to 69.

  41. Avataaar/Circle Created with python_avatars Kevin Barton says:

    i like how you look out for the customer and not try to rip people off. love your channel

  42. Avataaar/Circle Created with python_avatars Andrew Marshall says:

    Could you do a drawing of the engine cooling system on where the water and airflow goes and are there. Any internal parts that could be at risk if not done properly? Andy Uk

  43. Avataaar/Circle Created with python_avatars Jason Halverson says:

    flushing is good, it's those mechanics that automatically jump to replacing everything instead of fixing it that give everyone a bad name and make people think mechanics are just out to make money off you and cheat you. glad there are honest ones still around

  44. Avataaar/Circle Created with python_avatars William Albright says:

    Awesome job sir

  45. Avataaar/Circle Created with python_avatars Mars Patterson says:

    It would be interesting to see what comes out when flushing. Also, it seems likely, I'd think, that the issue is either thermostat or heater core, not both. Doesn't seem like much trouble shooting required to determine which. Or am I missing something?

  46. Avataaar/Circle Created with python_avatars James Ripley says:

    As long as the heater core not leaking and flushing it works what's wrong with year after year I had a 2003 S-10 I had to flush every winter for 7 years and it worked great .
