If I were to get my water pump replaced and the plastic crossover pipe.... does it mean that my problem is resolved? or does this condition go on and on and is locked in with all XKs with similar engines? I'm very disappointed that after all this time there is no fix for the our coolant/overheating issue.... So many years and no definitive resolve. Doesn't attract Jaguar customers..

Boca we need to take a survey here. So from 2009 until today how many 5.0L motors were built and how many have had bad water pumps. Also how many have had crossover pipes break and finally how many have had bad thermostats. When we get the results we can then make a determination if this is a problem.

Water pump failures on 5.0L engines have been a known defect for years. See my thread on the XJ Forum, which includes a chronology of the various part numbers: http:// https://www.jaguarforums.com/forum/xj-x351-53/survey-water-pump-replaced-132537/

I also had been smelling the faint odor of coolant for about a month but had not noticed any seepage or drips. I pressure tested the system a couple of times and both times no issue was noted. As a preventative measure I replaced the thermostat and complete plastic housing assembly. After about a week, my reservoir level has gone down by aprx 1/4" but I assume it was due to my utilizing my heater and such to ensure everything was flowing once again through the hoses and core. No more drop to the coolant level. I still have a faint odor of coolant but am assuming its from the coolant spilled during the T-Stat change. Not sure if I should also replace the water pump as a preventative measure. I have an 07XK na with 52000km (30000 mi).

Got it off the Topix site. Am I allowed to post service bulletins that I paid for on here?

Knowing this generally would answer your question and give you peace of mind, and I think a tech could weigh in here on your specific question.
If it's me, I'm pressure testing the system and would also slacken or remove the belt and check for wobble on the water pump pulley.
I don't have the 5.0 so I can only imagine your options for "seeing" a WP leak would be to use the coolant dye and then a video scope or remove the under cover and view from underneath.
If I wasn't doing my own work, I'd take it to my repair shop and ask them to do the same. I gotta believe this is 2 hours or less of labor from your mechanic.

You are correct. There have been many reports of 5.0L engines having defective water pumps failing prematurely with low mileage. Not so for the 4.2L engines, although those water pumps can leak with high mileage. Nothing mechanical lasts forever.

Stu I've seen the posts but my point is there is no creditable data to support this. I don't see the numbers and most likely won't . What we have is less then a handful of members on a small form. So if there are 1M engines built (?) how many water pumps failed. That's all I'm saying . I'm not refuting that a few have failed nor people are lying only that there is no data. Also if Jaguar has continued to upgrade their pumps then what is the reasons behind it. I come from a mfg. background in the semiconductor world. In that environment decisions were made on data as a process deviation would scrap an easy $1M in wafers in a few hours. I would like to see what Jaguar's data is.
The only way to get the volume of credible data you seek is directly from Jaguar, and I seriously doubt that they will voluntarily release it for legal liability and other reasons. Obviously, the reason that Jaguar is on (at least) the 4th version of the 5.0L water pump is because there were too many failures of the previous versions. Why did they fail? Because some design element didn't work as expected and had to be revised. Details? See https://www.jaguarforums.com/forum/x...placed-132537/ post #19 by johndalheimer, copied in part below:
"I devoted forty years as a seal engineer and engineering manager, improving water pump seal performance for Ford, GM and Chrysler, and others, and have been issued over a dozen patents covering these improvements.
I also took part in extensive technical exchanges with French, German and Japanese producers of such seals during this time, plus participated in organizations such as the Society of Automotive Engineers, advancing automotive water pump technology.
I know zero water pump seal failures, and therefore zero water pump failures is possible, because working with Chrysler on one of their more popular engines out of some six in production at the time, I enabled them to achieve such reliability.
My unique water pump seal design enabled and demonstrated zero failures under 50,000 miles, unprecedented in any automotive engine, by any manufacturer, up to and after that time.
Unfortunately, international conglomerates made sure this technology was killed-off and denied other automobile manufacturers world-wide.
Why? Quite simple. It is as lot more profitable to sell an inferior OEM seal, and then five more replacement seals for rebuilt auto water pumps in the huge automotive rebuilders aftermarket for the same car, than to sell one superior seal that would enable the water pump to last 200,000 miles, instead of, on average, only around 40,000 miles."
Jaguar water pump failures have not been of sufficient numbers to justify a recall. I just searched Home | Safercar -- National Highway Traffic Safety Administration (NHTSA) and found none.

Jaguar warns that you should not run the engine with the cap off as it could damage the engine.
Most kits that you rent from the auto parts store (which is usually just a temporary deposit) also have a cap pressure tester and they can show you how to use it. I realize you indicated you're replacing your cap but if the cap tester is in the kit, might as well use it.

Would someone on the forum know the latest part number for the 4th updated water pump for my 2010XK Coupe? (not the XKR) I want to make sure that if they replace it, I see that part number somewhere on the work order invoice. Thanks all.

Reading on the XJ351 forum, their latest part number (but the replacement was awhile ago) is C2Z31587. I've heard there are 4 updated pumps. Does anyone know that latest part number for the 2010 XK and does the XJ351 use the same water pump as my 2010 XK? Thanks all.

I would confirm with SNG Barrett or another vendor. They'll have the superseded part numbers.

Thanks Sean. I did call SNG Barrett and they too gave me C2Z31587 as the lataest part number. The best I could find on our Jaguar site was an XJ351 that had an install date of 10/2015 with that part number. I'm just hoping they have not updated this part within the last year. I'll call my local Jaguar dealership and see if their number coincides with this one. When I bring my car in I will make sure the service writer places this number on the work order. Thanks again.

OK I read the post and I have to say it reminds me of an article I read years ago about the guy who invented and patented the 100 mpg carburetor. The industry never adapted that either. I realize Jaguar will never publish the numbers so we'll just need to wait and see what happens to each of our cars. Then again it isn't something that will keep me up at night.
