I can't find the latest water pump version C2Z31146 anywhere on the web. Can anybody advise if any other part numbers are OK to use?

These are what I find available: C2Z31587, C2Z29189

Seems both are made by FoMoCo.

 

If I google that part number, many sellers come up. Please tell me you're not using Bing?

 

I did google but all those vendors don´t have them. Tried everysingle one.
I got on from ebay in the end. Not the same one but one made in Italy. Hope it holds up.

 

The latest part number is C2Z31587, as variant you could use the water pump from Range Rover 5.0SC, part number: LR055239. These pump the same for AJ133 engines. There are a few aftermarket suppliers produce this pump, for example Eurospare and Airtex

 

Great that exactly what I got. Guess I´m ok.

 

I just finished replacing water pump on my 2011 XF. all ok except some overflow pressure pipes crumbled like cookies. I need to buy the water pump vent hose, and the following as pictured. Where can I identify jaguar parts on the internet and get correct part numbers.

Thanks.

Anyone know how many hour labor this should take including the cross over pipe?

 

I did it in under 2 hours.

 

Any hints on how to get the little plastic elbow out of the front of it?
Thanks!

 

Press the ring and pull the elbow at the same time

 

I would recommend you replace the plastic piping/ hose parts. Better safe than sorry. It's like another $100

I replaced all the plastic in the cooling system with the water pump. Not cheap, about $1300 total in parts including the water pump, but worth it to me for the peace of mind.

 

You went deep.. I just replaced the parts that touch the pump, as numerous parts had been updated . However... you are good to go for a bit.

 

Yes, I did. The tough one to replace is the plastic assembly attached to the back of the engine. It's of a similar design of the one in the front that is known to fail, so I wanted it replaced also. It's hard getting a wrench on the screws for that pipe, which is what makes replacing it difficult.

 

So I just did this with a little help from my friends here. It's not that bad. Took me about 4 hours. Getting the little 90 degree pipe out of the front of the pump hardest part for me. Thankfully Bart let me in on the little secret of how to do that below(Thanks!). I could do it much faster next time. I did replace the plastic outlet pipe under the manifold in the front. My 2011 XF Premium has 31K on it and it was already leaking! Bad design! I just undid the high pressure fuel line going over the top of the manifold, undid the bolts, and propped it up a bit in the front and I was able to replace it with no issues at all.
I did not fully drain the radiator and such. I simply pulled the hoses and pump and caught what came out. I did put antifreeze in the hole in the top of the outlet pipe(before reconnecting it) as the last step of that part of the process. That fills the coolant pump with fluid. I hate the hose clamps so I replaced those with good stainless steel ones along the way. I refilled my fluid tank and ran the car for a bit with the heater all the way up. As the car has no temp gauge I used my OBDII reader to monitor the coolant temp to make sure things were okay. Everything works fine.
BTW...a good local Jag shop quoted me $650+tax to do this. I felt that very reasonable but I like to do this kind of thing so I passed on that. It cost me about $290 in parts to do it myself. If your mechanical this is a fairly easy DIY project.

 

Too bad you didn't go all the way and change out all the fluid. The radiator is due for a complete flush every 5 years, and it wouldn't have been that much more work. That orange stuff turns to slime as it gets old.

If you changed the spring clamps with those jubilee clamps, you'll be sorry about that. Those work ok on the old school metal pipes, but not on the plastic. They put pressure points on the plastic that will cause it to crack and fail. All you needed to do was spend a few bucks and buy the correct tool for squeezing those hose clamps, and they become super easy to take off and put on. If you were using some pliers, that's your problem.

$290 means you left a lot of plastic parts and a soon-to-fail water pump. The OEM water pumps alone is around $350. I did all the plastic including the header tank (known to fail), and with the pump, it was something like $1200 in parts. The cooling system is only as good as the weakest link, so when some other part fails, you'll still be stuck on the side of the road with a potentially ruined engine.

 

Actually I was guessing at the cost...it was really $279.55. I spent $160 on a new pump from Partsgeek. After getting 31K out of a Jaguar pump there was no way in heck I was going to spend money on an OEM part. They clearly don't know how to make water pumps and I don't drive this much anyway. Who makes a pump that can only go 31K...the answer seems to be Jaguar. If it had made it to 70K I would have bought OEM. The outlet pipe was $82.55 for an OEM part from Jaguarlandroverparts. Would have bought that POS aftermarket as well if anyone made them. I replaced the spring clamps(I have compression tool so that was not my issue) with stainless T clamps. I just think they look much better. The others look dull and dingy. I only did the larger hoses. Those cost $18. Gallon of Antifreeze was $19. I had the cooling system flushed and filled about a year ago(at 5 years) so didn't need to do that part. My car is a 2011 and has 30,803 miles on it. I personally find it ridiculous that I am even having to do any of this. I couldn't take much better care of it. If it had 60K miles on it I might have been looking at the other stuff but at this mileage I expect some more life out of those other parts. Unless you are telling me that Jaguars really are that bad!? I don't think I am off my rocker to expect to get to 60K with the parts the factory put on it. I don't drive it like I stole it.
