Water pumps and crossover failures on the 5.0 engines
#61
Bumping this as it is important for all to know to replace the water pump and plastic hose parts, especially the crossover pipe. I also filed the complaint on the NTSB website.
Happened to me about 3 weeks ago and going to cost me at least 2,300 from my Indy mechanic. Unfortunately replacing with OEM parts. Wish I could have located a site for the crossover pipe which was aluminium instead, but hoping this part will last another 8 years.

Yes. it lasted 8 years, I was one of the lucky ones. Some cars I've had never had coolant leaking issues, which of course could lead to catastrophic failures in our cars which we cherish for years. Yes, auto manufacturers decided to do this for planned obsolescence, which I hate. I'd have to say, however this is the best Jaguar I've owned.. Problems are starting to appear but it's been very reliable so far. Just a few maintenance issues like the front control arm bushings.

Mine was a leaky water pump. My Indy mechanic replaced all of the plastic tubing. After receiving the car back, I am hearing weird noises when I step on the accelerator. Kind of like valve noises. I brought it back to my mechanic and his lead mechanic said it sounded like the oil was bad. It handn't even been 3K miles since the last synthetic oil change, but I did it anyway. Turns out the oil was really dirty/brown. Not sure why that was, however, it was a slight bit quieter after the change, however a day later the noise reappeared louder again. I haven't pinpointed the noise yet and it has me worried that it could either be a cracked cylinder head, something loose on the exhaust manifold, or valve issue. I'm really hoping it's not a cracked cylinder, timing chain issue. It doesn't seem that I am losing any coolant anymore. I will have to have my mechanic take some oil and test it to see if there is any coolant in it.

One thing they could easy f-up is dropping something into an intake port since you have to remove the intake manifold to do the work. I made sure to stuff paper towels in the intake runners so I didn't do that.
Hopefully they didn't just ruin your engine.

Lotusespritse you make a good point that changing all the hoses and tubing even water pump should have no effect on the engine making noise unless they did something wrong and possibly dropped something in the intake.
I'm assuming you have the 5.0?
I'm likely going to have to replace the rear outlet pipe behind the engine on my 5.0 XJL, would I just remove the middle intake manifold and be able to replace that pipe myself? Dealership wants stupid money to do that, ain't gonna happen..

Not sure what that is, but if you are going to replace the rear or front crossover pipes, the intake manifold is going to have to come off. To get that off, a lot of other things have to be taken off. Once you get the manifold off, the 4 torx bolts holding the rear crossover onto the heads are a bear to get off and back on. It takes a lot of patience and time, but the problem is that you have to do it lying on your stomach on top of a very uncomfortable engine, so it's hard to have patience and spend time there.

Yes the big intake manifold meaning at the very top of the engine between the valve covers, maybe saying middle is confusing sorry. Basically once you take that manifold off your almost home free i'm thinking because that has nothing to do with the front of the motor, pulley's and water pump etc..., then you just have to lay there like you said and work on that pipe. Is there just 1 pipe or more parts? a few people said it was more than one part.
I'm wondering if you have the same 5.0 as my XJL, same exact configuration...

lotusespritse I have the big plastic top cover off but does your 5.0 look exactly like this? Mine is non SC thank god. I'm hoping if i take that manifold off, 10 bolts, and a few other little things I can change that rear outlet pipe. Do you also know if there is just 1 piece back there that needs to be replaced or multiple pieces also..Thank u.

So your saying just to do the water pump you don't have to remove manifold on the 5.0 but to do the attaching crossover pipe with it manifold must come off correct?
