All right everybody, we're back to that blue. Jag One more time we're we're almost done fixing all the little quirks this thing has a showed up with over the past six months and I say six months specifically because there is a problem that I've been looking for for six months on this car and I finally figured out what the deal was. Uh, we had an issue with this where it would, uh, it would just intermittently not, uh, not have air conditioning I found a few leaks on it every now and then, recharged it. it seemed to be okay and I was never able to catch the problem and it's been sitting here for about a month.

I had this thing connected to life support. there were monitors on it, there were meters on it, there were test lights on it, and I continuously was operating the system on this car. The AC with meters connected to the power and ground going to the compressor and after weeks and months of trying to catch this thing in the act, it finally occurred and I was able to capture and prove that the compressor power was shutting down almost all the way it was going down, dropping down to like four or five volts and all of a sudden it would work again and I would check it. We'd had 12 volts just like our battery voltage like normal and it was.

it was only happening for you know, 15 20 seconds after startup, then it would go away and then there was no problem. I've been into the dash on this car and I've been monitoring the HVAC control unit which was a up under the dash right here. it's way in there and I had found that uh, the HVAC control unit had stopped. there's wifey in it, it had ceased uh to supply power to the compressor and it was doing it very, very intermittently.

Again, my problem was I could never catch it in action. Watch. she's gonna park right in front of me. Don't don't park here.

No. keep it moving. Keep it moving. Don't park here.

she's gonna. She was thinking about it anyway. where was I Okay, so I would I couldn't catch the fall in action and again I continued to monitor the compressor side and I would monitor uh, what the voltage is and the grounds were doing at the control module. See, Uh, once the system is commanded on, the control head tells the control module to power up the compressor and then it sends power to the compressor.

Then the compressor kicks out and does the thing well. The issue was is when it was sending power down to that compressor intermittently, it was only sending out about four volts. So you're going okay. Got it? No problem.

Looks like we have a a bad HVAC control module. so I ordered a new one. Now I've got this thing about replacing control modules, especially control modules that have been in service for a very long time. Usually they don't fail on their own.

Something causes them to fail. So while I was waiting for the replacement control module to arrive, I continued to test and monitor the system because I knew I was on the right track and I knew I was narrowing down what the deal was. So what I did with the system running is I waited for the fault to occur when it occurred. I supplied 12 volts of fused power directly to the compressor and it was blowing up the fuse.

It wasn't doing it consistently and what I had found is that the circuitry of the control module was affected uh by The Fault in the compressor. So I I do have a control module in there on the shelf and I've got a compressor that has been ordered. it's on the way. I'm going to change the compressor first and then retest and if I find that voltage being supplied to that compressor is intermittent or it's dropping below you know, battery voltage or 12 volts something like that while running, then I'm going to go ahead and toss in.

Uh, toss in that other module and I know what you're saying. you didn't record it so there's really no proof and and you're kind of right. But like I said, this is a month-long uh Endeavor of me trying to figure out what the deal is and I was actually kind of annoyed once I found out that the compressor was faulty. Uh, for a couple reasons.

Uh, reason number one is this compressing unit is uh, it's about a year old I I did not install this, somebody else did Once Upon a Time it's down there somewhere. but uh, you know we were always operating under the assumption that we have a brand new unit here and I forgot to remind myself that new does not mean good. It means it's not used very much. So let's restart this engine.

Let's power up the system because I found another symptom that we were overlooking again because Hood Gravity re-popping Z Hood Because we thought that the situation was a power steering concern, not an AC concern and it's not doing it now. but intermittently. One of the complaints was is on. Startup the power steering pump was making like a a grinding whining type of buzzing noise and again it was only occurring for a few seconds and then it would go away.

and I found out while I was tracking down this compressor situation that it actually was not the power steering pump, it was in fact the AC compressor also making that sound. I've never heard compressor make the sound that this one was making and I wish it was doing it right now, but it's not. Maybe it'll start winding when we get inside. but regardless, I've got one two I think three ways that uh, I have condemned this compressor.

So we're going to go ahead and get this thing up in the air, pop that guy out of here and uh and get it replaced. So stay tuned because this it's probably gonna be the final video on this. Jaguar because I fixed everything else once I fixed this. It's good actually I lied.

There's also an intermittent check engine light. uh I forget the code. uh, the code says something about fuel rail pressure is too high. It's telling me I have too high fuel pressure I've already verified the wires and I think I put a pressure sensor in at once upon a time.

but uh no no no no, it was a fuel pump because I had low fuel pressure I Remember now but yeah, it's got a code intermittently it says fuel rail pressure is too high I'm not sure what the deal is with that. I've uh I've been stumped on that one for a long time as well. Um, any Jaguar guys know what's up with the too high I feel raw pressure on uh on the old Xjs. Let me know in the comment section.

Anyway, that's enough fishing for uh, viewer interaction. Let's go ahead and get this thing in park and get started powering down. Let's see. So here's our compressor up here.

We can see it's a fairly newish. uh, there's that connector. Um, yeah, so this is gonna be fun to extract because it doesn't come out this way. It can't go up because there's other stuff in the way.

so it's obviously got to come out through through here somewhere. I'm probably gonna have to pull the subframe down some to get some space. Um, this will be fun All right. Well let's pull the wheel off and get started.

No sense I'm staring at it. It's not gonna get fixed that way. once I start moving like a diesel. Hard to get going.

but once I'm there I don't stop. Nuts are swollen. There we go. Step one complete.

Come here. Okay, it's become very clear to me that this fender liner thing has to come out at least I hope it does because I'm taking it out and if I take it out and find out I didn't have to take it out I'll be sad that I took it out. Shoot rambling on that big one didn't fit I need to get the middle one out. Where are you? Yeah, it's held in with a bunch of these little plastic push Clips Okay, now in typical uh European Vehicle fashion, we've got some Torx Fasteners mixed in with the the plastic connector clip things here.

and why do we need torx bits in lieu of plastic connectors? I Don't know, but we got him and a washer. you know looking at this in Greater detail I uh I think I don't have to remove this at all I mean I'm not going to gain much space by pulling it out, but I'm just gonna go ahead and finish it off. I See no reason to back out now from here. Oh, another washer.

Yeah, someone's been here before. These washers aren't supposed to be. You know? back you guys up a little bit. let's fish this thing out.

I Got a text message. that's why the radio stopped come out plasticky bits. There it is there you go. Step that down right over there.

Perfect All right, we're moving back up to the run of the engine here. We need to reach up in there and get a tool on that belt tensioner and go ahead and pull pull that loose so we can get the belt off the compressor. So what? I'm gonna do stick this guy up here and see if I can't reach in and plug in the ratchet to the the drive thing on the tensioner. It looks like we got it.

and yeah, it goes that way counterclockwise. Lefty Loosey Tensioners on tension and I've got the belts off of the compressor. There we go. Okay, let's move back into the wheel well and work on those lines next.

Actually, I think I'm going to work on the subframe next because I can't even get to the bolts. See that right there? That bottom bolt that runs right into the subframe. So yeah, I got to pull this up frame down just to uh just to get the scene to come loose. So let's uh, let's do that next there.

there's one of the mounts for the subframe there. Let's get in with the now with the angular impact and pull that bolt down. I'm gonna try to do just the two on this side and maybe the thing can just lean down. It's kind of the idea and we'll see how it works out.

Okay, that's in. Let's get the other Mount over here down right there. I Think we're looking at 15 millimeters because the engine came down with the subframe. but we did get uh, more space over here.

so I can squeeze this thing through. I Think let's get uh, let's get the jack stand and take this down as far as we can. It's good. Raise this thing up some all right that's gonna hold the weight.

then I can pull the rest of those two bolts out and this thing will be free from the frame on this side and we can try to maneuver it from there dirt. Cascade A big bowl? Let's see. I can pull this one out the rest of the way. now.

come here. Seriously got it. You go over there next to your brother and all right, we'll pull this guy a little bit looser. Okay, it's not gonna come down anymore.

That's all we get me. They got to disconnect the strut. Hey, let's go up here and pull these. uh, these little nuts out for the strut.

See how this drive went down? Let's see how far we can go with this one. Let's see, we'll put that one on Three turns. Pull this guy out. That's about all we get I don't want to go any farther actually I don't think I have an option I need to pull this out the rest of the way.

Uh, let's remove this connector if we can. Yeah, that was easy. Came right out Okay, oh, let's let her down some more. That's about all we get.

Yeah, it's uh, it's done coming down. Hope that's enough. Okay, so since the subframe is now lower, the engine is now lower which does not give me any extra space. So what I need to do is keep the engine up higher and then get the subframe lower.

So I will now unbolt this engine mount from the subframe, down through that hole right there, or up through that hole. and then we're going to use another jack stand to push the engine up so I can create some space here. Fun clicks, foreign. So what I'll do is I'll move this stand over here to hold up the engine and that'll let me lower this stand down.

If I can get this right, clearances and whatnot, you know that should be good. Okay, engine's going up. subframe is staying down. Now we're talking.

Hey look there's that bolt that I couldn't get. It's coming into position a little higher. This is a this is weird. There we go.

See that. All right, 10 millimeters we have contact on clips. haha. Yes, Finally, we're getting somewhere.

don't know where we're getting to, but we're getting there. Hey, a nut fell out. That was weird. Anyway, there's my Bolt look at that.

The nut that fell out of it has got half of it ground down. See that I don't know if that's Factory or not. that's I've never seen that before unless someone did it deliberately. Okay, so I've got the bottom bolt out.

Let's let. uh, let the engine down, keeping the subframe also down and we're gonna go down as far as we can until I can reach the top bolt and the back. Bolt for the compressor. Okay, now the there's another bolt back here.

There's I think there's three for this compressor. Third one's in the back. Oh what? That one's not even tight. Let's see it.

You can't see it steering on here there. Now you can see. Look at that. that one's not even tight right there.

It's just. uh, we be wobbling. Hang on here. let's get that thing out.

Well, the situation is not not boating well for this last installer of this. Okay, okie dokes, we've got one more. one more Fastener here that wasn't very tight either. Oh the shame.

Wow, really Here it comes here. It is all right. that's three bolts. This thing should be free.

Yeah, nope. stuck pry bar. Just get behind it here and try it towards us. I'm sure it's just got some alignment dowels or something to hang on to it.

There you go. Okay, now, a little higher up we've got the two connections for the hoses. Those are gonna be fun. Yeah, you see them up there on there and one over there.

I've got to reach up with a wrench. you know, get those disconnected. Okay, we're going in Long Reach with the ratcheting wrench. Hoping to get a hold of these these bolts up here.

unless I have to get them from the top. That's a tight squeeze up there. super duper tight. Yeah, that one's loose.

I'll be able to get it out, but you guys aren't gonna be able to see trying again. I've got my little stubby ratcheting Crow's foot little device. that's enough to get some turns out of this thing removed. there.

It is all right. So that's one of the bolts for one of the lines, which they're both under vacuum right now so those don't want to come out. Okay. going in for the line number two.

that one's actually a little farther back than the one I just did. This is really fun. I can't even see what I'm doing and I can't get this from the top. There's like no visible access here.

This actually sits under the V of the engine. so if the if the V is going like this, the compressor is down under it. so I can't get a any line of sight at all. Okay, got a wrench on the bolt that was took some finesse.

all right, unclear. Okay, yeah, we're getting somewhere now. It's loose. Come on.

Jaguar Yeah, that Line's gonna be fun to put back together. I'll tell you what. I can't even get tools on the bolt. You know this kind of stuff wouldn't be so bad if you could fit two hands in these positions.

You kind of can't see super duper no space here. All right man, it's got to be close. Come on. Yeah, there we go now.

I got two fingers on it. I will defeat you and now I figured out how to put it back together too. All right, there's the bolt right right there. Got it all right going in.

Let's go ahead and get these lines detached. They're only being held in place with vacuum from the recovery machine. I can just get under it with this little pry bar thing here. it'll pop up there we go.

There's one pry bar for everything. that's line number two. All right. So it's free.

Unit is now free. It's just kind of floating around in here now. I just need to maneuver it out. That's the next challenge.

I Don't know a little bit more up and I think I got enough to get this out I think because here's the tightest of all tight squeezes. I think I've got over here on the left I Pry barred the subframe down and I have a socket wedged in here there. Oh, you can't see. there you go.

There's a socket in there. stuck pry bar right here. pulled this thing down, stuck a socket in so it's holding the subframe down. the engine's being held up and I think this is enough to get this thing to come out.

I think I hope because if I'm wrong. uh I don't have some problems here I might have to pull the sway bar out. No no no I got it. Yes, she's out.

Uh, what a relief. we're getting somewhere to the bench. Let's go check out. uh, this unit compared to the new one.

I'm sure it's gonna fit and we'll get this guy installed. This is a faulty, newish compressor. Very unfortunate. Get this stuff over some tool gravity.

No worries, it was just a 10 millimeter foreign. Our mounts look the same. there's three, our connector is the same, and our manifold and ports also look like they're the same. So what? I'm going to do I'm gonna go ahead and pull these bolts out of these ports that way.

I Don't have to worry about it later. Pop this guy off. pop. Okay, set that right there.

come out okay. Come on. New compressor coming with us. See how this is gonna work here? Get it SPID back into its home here.

same way the old one came out, which is opposite of what I'm doing. Yeah, hang on. we're doing this fast backwards. I Think the the spinny end came out first.

Let's try that. I Honestly already forgot. it's been like 45 seconds and I forgot it's been a long week. I know you go in there.

so let's just get with the program and do what you're supposed to do. Come on so close right here and there's alignment dowels in the bracket that are going to hold this. Yep, right there. That's where it goes.

Nice. Okay, before we get all excited and bolt this in I Want to get those lines installed so we're gonna pull little plugs out of there and get the lines fed into position here again. Yeah, y'all can't see what I'm off to. it's too dark.

super dark in fact. I can't even see what I'm trying to do. Where's the hole? I See it. There's a hole for the a, uh, a roll pin and sticking out of this compressor.

and I'm supposed to line up that roll pin with the little manifold flange on the hose and that's what sets the alignment. And naturally I'm having a hard time getting that to a lineup because because Jaguar and I can't see it because it's on the other side of the unit here, I'll just keep wiggling it. it'll go in. Okay, so it's it's lined up.

but uh, the roll pin will not press to that little flange. So I'm gonna put the bolt in it and start the bolt and hopefully that bolt will, uh, will draw it back down. No space at all to work with. this is so agitating.

You know it's not really that bad. I'm just kind of grumpy and fatigued from earlier operations that I was conducting this week. Okay, the bolts starting. We're going in.

Okay. this is going to take a while. Isn't it all right? It's getting smooth now. it's starting to slide down over the PIN.

You guys can't see the pin. Like I said, it's on the back side. but it's going. Let's keep drawing this down.

Okay, let's finish that one off with the larger ratchet. We're almost bottomed out. I'm running out of flangy strength here. Foreign.

Okay, let's finish this off with the full-size ratchet. It's a it's almost bottomed out and I'm having a hard time turning it with the little finger ratchet. so we'll get this big guy in. Ah, Blinded by the Light too much lumens? Yeah, let's see if I can just get if I get a finger on it through here I can hold it I'll bear hug it again and try to bring this.

uh, up the torque here. it's gonna take a while. slow and steady. a couple clicks at a time.

Not fun. Come on. AC Hose: it's almost there. Come on a little bit more Raw and one more pull for good measure I Know you guys can't see I'm really sorry.

stick that has one hose installed. Let's get the uh, this other one installed and then we'll bolt this thing to its bracket. Here's our plug, one down, one to go. Let's get our little Peg lined up and then we'll get the big Peg lined up and we'll get the bolt in.

These angles are all weird here and these hard lines are not very forgiving. They don't really have a lot of motion. There we go. Now we're lined up.

kind of. Yeah, buddy. That's it that went in All right. another 10 millimeter Bolt Slide that guy down, get you started.

Oh good. That one's going in a lot easier. I Don't think you can see? Nope. I can't see, you can't see, We can't see, but we're all in this together.

Unless you click away, then you'll be somewhere else. That would be bad. Oh, come on with it. All right.

that one's down. A little bit of increased torque on that so it stays tight unlike the mounting bolts. Oh, it takes and take this guy and put it back up in its position on the bracket. That's a flashlight.

Saw that coming. Yeah, there we go. Put our illumination back up here. These just stay right there.

Okay I don't remember. These are all three different lengths. All right. this is the bottom one because that's the one with the little shaved off nut that probably isn't supposed to be there.

I would be. uh, willing to wager. Threads and the bracket are stripped, reaching around on the back side to get that nut on. Yeah, those threads are stripped out.

This bolt doesn't even go here. it's too long. Okay, next one that's going up top. what are we doing? We'll push it in some wiggle it.

it doesn't go wiggle it and then it goes all right. wobbly 10 coming in kick, two clicks and where's that other last little bolt that I do. It's in my pocket. Run this guy down.

Yeah, that one's stripped. All right. That's why it was loose. it's stripped out.

Cool. Why? All right? Well, what do I do about that? Let me see. what do I do I Oh, that's not okay I don't have a uh I don't have a way to put a Fastener on the other side of this stripped out Bowl right here. And this is kind of important because it's the only one.

Hmm I think of something here. Oh I know I know what to do I have an idea. Okay, here's here's my solution: Some grease and some wire. The grease is to make the wire stick to the bolt.

I've got the end of it bent down so I can get it to go into the bolt hole and I'm failing. and I'm basically going to wedge this bolt in between the stripped out threads and the bracket and in between these pieces of copper wire. What it's going to do is it's going to smash that wire down and then it'll be able to grip remaining surface inside of that bracket. That's the plan here.

so you're going to work or it's not. and if it works, we're in better shape than what we started and if it doesn't work, then, well, we're in the same position. So we're gonna put this thing in and send it very carefully. I Don't want the wires to come off of that little bolt there all the way in.

That's it. All right. This might take a couple of attempts, but it's better than nothing going. haha.

Hear that thing bogged down. It's working a little bit more. Click? All right. That's better than nothing.

It's got some clamping force on it now. Sure, let us proceed. Thank you. We'd get the connector connected.

That's easier from up here than it is down there, that's for sure. And I think this clamps on somewhere around here I Don't know where. Um I figured it out. There is a there's a bracket on the old compressor.

We'll bolt that thing onto the new one and then use that bracket to secure connector. I Think that's how we're supposed to do this. That guy down right down. Come tight please.

thank you. Then this. You can plug in and look right here. Yeah, that's how we do that.

Look at that. That's nice. It's much more better. We'll snug down that little bolt with some eight millimeter action.

Foreign click. All right. Well, while we're here, let's see if I can't get that belt in position. let's see there.

reach up. Pretty sure I can get it on from where I'm at. I can give that uh, that ratcheted tug and untenching our tensioner here to miss. All right, belt's on.

Give me back my ratchet. Got it ratchet recovered? Uh. visually inspecting the belt. it's on all the ribs.

That's good. Okay, let's get out of here some and pick the subframe back up and get the engine bolted back down. I Need to unpry Bar my socket. See you right there.

We're gonna get under this guy. Give it some down socket recovery. compete. It's like a another bracket stabilizer Mount thing.

Jaguar stuff. Who knows, bro. All right. Big Bolt Coming in, let's get all this stuff lined up better.

line up. Yeah, it's a little. it's farther back than it needs to be. I'm gonna let the engine down onto the subframe and I'll bolt that in next.

I think and then I can pry bar the subframe forward and get that hold of mine back up. All right engine is now sitting free. let me run the bolts in real quick and then uh, we'll go back to some pry bar action. now.

where are you wait in there? All right Motor mount clicks. that one's in. Oh, curiously enough. I uh I Checked the other side and found out that the lower bolt was missing.

So I uh I find one to put inside of that too. There's a not missing for the motor mount. anyway. I'm gonna raise the subframe up some and we should start to, uh, see this hole become aligned over here.

I think a little bit up a little bit more up. Yeah, there we go. Get that. AC line out of our way.

not up enough to start the threads though. so up a little higher is that gonna do it? Nope, it's close. Let me try the back one and here let's see if I can get this back when we go in. Foreign yes and I need to re-tighten this one now.

Can I get that one to go in? Let's find out. Survey says yes, it is threading now. Good foreign. Let it move around a little bit.

Get in there here. you guys wait here. I Can't reach that stupid thing. All right? That's all four subframe bolts.

Good to go. How are we looking Tight? That's tight. Compressors in belts on. Okay I need to go up top, put the strut bolts in and while we're up there.

I'll pull this thing into a vacuum so I can recharge it later. see I Don't think we need these anymore. Right out of here. Let that one down.

get you out of here. Very good. All right. Moving back up all the way up.

Let's get these nuts back on the strut at these. Got four of these guys. Oh fail. look.

I grabbed the wrong electron clicking device I have too many impact guns. Now that's gravity. That's a lie. You never had too many hot guys and we shall not neglect the connector for.

The Airliner Whatever this thing is, what are we doing and why are we doing it like that? It's problem here. There we go. It takes all right. system's vacuuming.

Let's pick up some of the mess here. I'll let this thing down a little bit and then we'll get that fender liner reinstalled. All right. Let's check on our machine.

Uh, 2.5 minutes remaining. I'll be back in 2.5 minutes. Don't go anywhere. Okay I actually lied, it's been longer than 2.5 minutes because I was inside of the cabin.

uh, putting all the paneling for that computer module back together. So uh, let's just go ahead and fast forward here and charge this thing. I believe it takes 1.4 pounds refrigerant it's not electronic and then we will stop to use the engine and see if this thing's gonna work anyway. I Want to see if that stupid noise is gone? I Know we didn't hear it when we drove it in, but I've been hearing that noise for like six months.

Foreign refrigerant on the high side? Please send it full send. Let's do it. You gonna go? You gonna go? You gonna go? You're Gonna Go You gonna go? Are you gonna go? It went all right. Okey doke.

So the machine just beeped so it has completed its recharge. Let's restart this thing starting Z engine and powering on AC As soon as the controller is done. that's good. Oh, we're already getting temperature drop.

Awesome! Let's go check our gauges. That thing came on instantly. It usually took a few seconds and then it would come on. Yeah, pressure's coming up.

good. Pressure differential. Okay, this is gonna take a little bit more monitoring just to make sure we're good, but I'm not hearing a groaning noise that I heard that we thought was a power steering pump or or an air pump. It's not doing that so it came on instantly.

This is good. Pressures are good. It should be making cold, but that's not a good mate measurement for the day because it's kind of cold today. But yeah, we're already down.

Well look at that. it hit 40 40 degrees fast. 40 is the green right there. A little green little Notch I don't know if you can see it, there's a glare.

Yeah, this thing hit 40 degrees Fahrenheit quickly. Wonderful! We're good to go here. I'm pulling this for the success finally. Uh, the only thing I have left to do in this car is get a replacement uh, sealed for the bottom of it which I could do that later.

So uh, all that being said I'm gonna go ahead and get my machine back and we're gonna go ahead and uh, button this thing up I'd really like to get it back to the fella that owns and he misses his Jaguar So all that being said, as always, just like, thank you for watching this video. hope you enjoyed my video. If you did enjoy this video, please feel free to let me know about that in the comment section down below. Tap that like button while you're down there.

And most importantly, do not forget to have yourselves a great day! See you guys later in the Jaguar.
