There is some consensus in the XF forum the latest revision which is number three or four may have a better seal design than the previous designs. That does not however fix the issue of the cheap plastic pipe that will also fail at some point.

 

There has been a lot of discussion on the XJ Forum about the water pump. See: https://www.jaguarforums.com/forum/x...-132537/page3/ See post #43 and newer. To summarize (and my thanks to XJsss):

"There have been 3 versions of the water pump for the 5L engine. Below, the first picture is the latest version that in not stamped as FoMoCo as was the two previous versions. The latest version is made in Italy and is a different design. I hope this is the final fix for our premature water pump failures.


...if you look at the water pump and can see an oval with Land Rover cast into it is the new pump. I tried my best to take a picture of it but you may have to zoom in to see it. (Go to the XJ link post #44 and enlarge the thumbnail photo and zoom in to see that LR oval below the top of the belt and to the right of the pulley - see the red arrow).


The part #is C2Z31146. The latest pump was not available till April or May this year and Jaguar may be still be shipping the old style till they run out. If anyone is getting the pump replaced make sure that the dealer orders the new part and refuses the old style."

Thanks Stuart for posting this. Even though my cars are still under regular or extended warranties I've just purchased the water pump on Amazon. Gives me a little more confidence for driving the car at distances.

 

Here is the reply from the Amazon supplier regarding my order and a change in part numbers:

Order ID 111-1744429-1973844:
1 of Jaguar C2Z31146 Water Pump [ASIN: B014I5H64A]

------------- Begin message -------------

Hello, the water pump you ordered C2Z31146 supercedes to a new number C2Z31587. The price is the same 189.00, we just wanted you to be aware of it the supersession. We are in the process of updating the listing in Amazon and will ship your order immediately. Thanks.

Albert,
That's interesting - I wonder how long it will be before there is another new part number for the water pump. Any idea what the difference is?

My question is this. Can anyone with the latest version of the water pump attest on this forum that 1) they know with certainty they had their water pump replaced with the 3rd version and 2) that it is still holding up?

 

Just to confirm that the C2Z31146 is the newest part number which supersedes C2Z31587. Same pump, as posted by Stuart, now made in Italy. Also visible the Land Rover stamp, differentiating it from the FOMOCO pumps of past. Sure hope that this is finally the solution for the water pump issues. I purchased it for "spare" only, in case I need it in a hurry :-).

 

Ive heard from some of my UK friends its good to think about replacing the water pump every 25-30k miles.

 

Click on the link below for a great story with a happy ending on the XJ Forum about the outstanding Customer Service by Jaguar North America. The dealer wanted $1600 to replace the water pump on JagGuyMD's 2011 XJ that failed at 39K miles. Jaguar Corporate came through and picked up the entire cost, even though the car was out of warranty. Truly a great Christmas present!

I had the water pump replaced on my XKR-S at 31000 miles. I could smell coolant after shut down. No sign of coolant loss from the overflow tank but it must have been losing some. Dealer said the pump was leaking from the weap hole. Cost to replace was originally $1750 but after some negotiation it was reduced to around $1300.

 

Ouch! What's your dealer's hourly labor rate and how much time did it take?

Amazon sells the pump for under $200. It looks to me like you just got screwed without having any fun.

The 5.0L water pump is a known defect and at only 31K miles it should have been replaced at no cost even if you are out of warranty. I would write to Jaguar North America and ask for reimbursement. See the link in Post #29, above.

 

some give lots of warning like noisy bearing, small leakage to none at all. I have had cars i did a service on and no noise no leaks come back the next day with a bad leaking pump.

 

The service history on my new 2010 XKR showed a water pump replacement in 2013 so I figured that was one thing I didn't have to worry about. Based on what I read here, I may eventually need another one. Rats.

 

Was quoted 6 hours labor. New coolant, latest spec water pump, gaskets and seals. Dealer charges list price for the parts for sure but I know it is done right. I have a year warranty on parts and labor and know the coolant system has been bleed correctly. Indie wanted almost $900.00 and had no loaner car and warranty on parts only. Parts.com is usually as cheap as Amazon and you are guaranteed original factory parts from them. Call your dealer and ask them to quote it. I think you will be surprised. Not much room to work on these cars and my days of doing this kind of work on 90 plus degree heat are gone !
We own cars that had a high initial cost, the maintenance will be expensive even though some are only worth $20k.

 

Partsgeek.com shows a water pump for 2010-2015 XK and XKRs. But from three different manufacturers. I wonder if any of them have solved the design flaw in the Jaguar OEM model?

 

All water pumps are supported by sealed bearings. A sealed bearing is just that - sealed against any outside source. In theory, a sealed bearing should last indefinitely. But, should the seal be broken, anti-freeze will contaminate the bearings, leading to bearings failure and pump failure. Seal leaks can range from minimal to catastrophic. Usually, a seal leak will evidence itself by fluid leaking from the water pump housing. It doesn't take tech knowledge to see a leaking water pump - just a flash light and maybe a small mirror.
Bearing seals fail by reason of coolant pressure against the seals. If the coolant is not under pressure then the bearing seals have a much better chance of resisting coolant intrusion. I use Evans Waterless Coolant, which operates with zero coolant pressure simply because it has a much higher boil point than conventional coolant.

 

My water pump was replaced yesterday by my Jag dealer ~ 600 EUR - 8 hours job, and they needed a special tool to lock it into position, so they borrow it from another shop.
