I thought it would be helpful to list the water pump part numbers in chronological order, with the newest version last.

C2Z29189 - Installed in my 2013 XJ on 12/4/2014 (so far, so good but I keep my eye on my OBDII/Torque temperature gauge)

C2Z31146 - Installed in johndalheimer's 2011 XJ on 8/11/2015 (embossed with Land Rover logo)

C2Z31587 - Installed in polyesterpig's 2011 XJ on 11/18/2015

If your water pump fails, make sure your dealer installs the latest version.

 

Can confirm that C2Z31587 was installed on my 2011 XJ 1/18/2016 at 35,000 miles.

 

Got my water pump replaced twice already. First time, around 25,000 miles on it. 2nd time, just 2 days back with 32,000 miles. Pump was fine the second time - apparently the outlet pipe started leaking coolant onto the serpentine belt. Both covered by warranty. My car is a 2012 XJ SWB NA.

 

What is the part number of your newest water pump? It's on the invoice.

 

2011 xkr175 water pump replaced at 18,500 as the dealer notice it leaking. under warranty, thankfully.

 

2013 XJ V6-AWD water pump replaced at 18,511 miles, 3 years in service (March 2016). Dealer noticed leaking coolant. New unit part #C2Z31587. Still smell antifreeze 3 weeks later although fluid level has not gone down. If smell does not dissipate soon (currently assuming it is residual burn off) we will likely take it back in for a pressure test.

 

I had that smell forever in my 2011 after coolant leaked all underneath the car. You need to run it through a few undercarriage washes/rain before it starts to get better. Took driving 400 miles through rain on a trip one night to really go away.

 

What is the part # of the new pump? It should be on your invoice.

 

Some techs are better at water pump replacement and there is less spillage and they also pressure clean the engine after the replacement. My coolant smell lasted no more than a week. Yours will go away eventually.

 

Just had my water pump replaced on our 2011 XJ S/C under CPO warranty. No smell of coolant apparent.
Car was at dealer for 96000km. service (actual odometer reading 82800km.) and was checking supercharger for end play and could see low coolant level in the overflow tank. Pressure test revealed the w/p seal leak.

 

What are the requirements of failure for Jaguar to change the Water Pump? Could it be as simple as coolant smell or signs of it on the plastic bottom engine cover?

 

Read my post #1 - all it took was coolant smell. The tech found the tell-tale drip signs and replaced the water pump under warranty.

 

Mine was rattling / making a noise when it was in for service and they replaced it before it had even lost any coolant. Think they are quite adept at spotting it now and would rather not strand a driver by the roadside or risk overheating. I was grateful for the attention my dealer paid to that

 

I got my XJ supercharged (2011) a year ago. The pump was replaced by the dealer under warrant in 2014 and it's leaking again. Needless to say, I'm not happy at all.

 

Looking at a 2011 XJ and the Car fax says the water pump was replaced 05/2013 at 21,927 miles

.

 

I just had to replace the water pump on my 2011 XJS as it failed. 23,000 miles.

 

Do you happen to know your water pump part number? Apparently there have been a total of 4 updated water pumps.

 

sorry, i don't know the number. had it replaced at a firestone dealer and did not think to get and keep the serial #.

 

Why doesn't Jaguar just change every f.....g water pump and crossover pipe in all 5.0 engines after 2010? We all know they are crap and will fail sooner or later and have probably been seeping coolant since day one. Not right... This is one reason I would never buy another Jaguar after my XK. Lexus or Toyota would never try to push this under the rug and takes care of issues as they arise. That is why Toyota/Lexus is where they are and Jaguar/Landrover is where they are.....at the bottom...Too bad.. A Luxury brand but inferior customer service. There is a saying.....Any car is only as good as the service it gets. Bingo.

 

Just had my water pump replaced at 38,000 miles
