Can we talk about the 5.0L water pump

[QUOTE=shemp;1837336]AJ813909[/QUOTE)YesI see that part number does supersede the most recent number C2Z32587. Unbelievable how many part number replacements they have had for the original factory part. How many times does it take to get it right?

How Many Times Does It Take To Get It Right?
I just posted this on the X351 (current XJ) Forum. It details the history of the 5.0L water pump part numbers. So far there have been 8! Stay tuned; it ain't over yet! Here's the link to my post #106: https://www.jaguarforums.com/forum/x...-132537/page6/

It makes one think that if this part has been superseded 8 times, firstly 1) have all those 8 replacement pumps failed as well? and more importantly 2) how much confidence should we have in the latest pump???? After 8 attempts what has Jaguar discovered as the real culprit now? It's amazing, because the basics of a water pump are inherently quite simple. How many other car manufacturers have water pumps that last 150-200,000 miles? I don't get that warm and fuzzy feeling with Jaguar.
PS....I wonder how bad my water pump must be if it was the very first one made for the car????

This thread is quite a sad but interesting read. Subscribed! I am looking to buy an XK/XKR 2010 or newer. To date I have test driven about 4 vehicles. Two of them had a clear coolant smell noticeable when you opend the hood, both at approx. 40k miles. The other two with about 30k mileage did not or at least I didn’t notice, but for one of them I was checking... smelling... very throughly.

I’ve had the coolant smell about the the time of purchase 4 years ago with 4,800 miles on the car. Now with 10,000 miles the smell is still there and dealership still refuses to admit any seapage and will not replace pump. I’m planning on trying a different dealership before my Easy Care warranty runs out within the next 1 1/2 years.

Unlike your situation......I've had to add very small amounts of coolant over time. Of course, considering I drive so very little, the amounts I add are also quite small, but never the less, coolant is still disappearing. I did have an independent (that I trust very much) as well as one Jag dealership check the water pump weep hole for any sign of seepage or crusty residue and neither were able to find anything. If it is leaking anywhere else, nothing has been found so far. My feelings are that considering it is a known fact the water pumps are faulty, I'd prefer to change it now while I still have a warranty and at least get that out of the way.

Agree 100%, if you have an original pump. I was simply getting an occasional 'cooked coolant' smell and slow coolant loss, nothing dramatic. When they changed the pump at my request, they told me the bearing was almost gone.

But:
- It's reasonably easy to detect a leak - the smell of cooked coolant is pretty distinctive when you stop (smells a bit like burnt plastic or candle wax)
- It's not an excessively expensive fix - probably worth getting it done regardless, if you're having any other engine work done.

What I find to be particularly interesting is where are any posts of those owners that HAVE HAD THEIR PUMPS REPLACED with any of the part numbers that have already been superseded. We are talking about from the original pump to the very last pump Jaguar is now using. Do we have any proof of these pumps failing as well? Why so many updates to the design unless all these replacement pumps were faulty as well? What's up with that?
