Water Pump Replacement

Water Pump Replacement
Just had mine replaced after getting the 'cooking antifreeze' smell. My indy specialist said the bearings were almost seized on the original pump, so just as well I got it looked at. The part number they quoted in the invoice was AJ813909, which is supposed to be the latest version of the pump. Can anyone confirm that?
Incidentally, also had the following done:
It's 7 years old, so I guess this is the point where these sort of things will begin to appear.
Incidentally, also had the following done:
- New front discs (severe corrosion)
- New gearbox filter & fluid
- New screen washer pump (minimal flow)
- New pedestrian protection sensors (kept getting fault on dash)
It's 7 years old, so I guess this is the point where these sort of things will begin to appear.

Nice list of maintenance done!
One thing does pop out that they missed, changing the E-Diff Fluid. At 7 years old you should really consider getting that done. It should be cheap compared to the other items on the list and your E-Diff will love it.
OH, from what I have read lately that is the latest pump. Parts lookup also show it is current pump for 2018 Model V8/V6 F-Types.
Hope that helps,
Dave

Mine smelled steady for about 2 months after the pump replacement. Now, every once in a while I'll get a whiff of "sauteed antifreeze" when I pull in the garage. Coolant level has been steady though. God I hate that smell!

Agreed, AJ813909 is the latest part number. See my post # 183:

If you smell coolant while you're driving, it may be too late.
Time to plug in your ELM327 Bluetooth OBDII reader, connect it to your Android smartphone, and monitor your water temperature on the free Torque app.

Do you know when you last changed your Coolant Reservoir Cap (radiator cap)? In my experience the Ford style Caps only last a few years (2 years was shortest). I have been replacing everything like that on mine and when I installed the new cap it was dramatic at the difference in resistance of the rubber seal. Gonna add it to the 2 year plan on my 2010 from now on. At $7 or so, it is money well spent.
First time if happened to me on my 05 F-350 Dually I drove around cautiously for a year thinking I had a head gasket going bad (it's a diesel thing), it would lose coolant and even whistle at times. It was so bad I even drove it for a while with the cap loose. Just for giggles I ordered a new cap (same exact one that is on my 2010 XKR) and all of the issues disappeared.
Try this simple test, go drive your car for at least 30 minutes, then let it sit for 5-6 hours and loosen the cap, if you have no pressure or very little pressure left consider replacing the cap. Sure, it may be something more ominous, but it is a cheap and easy thing to do.
Cheers,

Do pigs fly??? :-)
Part Number: C2P17700
reservoir cap 5.0 LITER W/O SUPERCHARGER, to VIN B36760
MSRP Price$11.65 Online $8.11
EDIT: OH, be sure to tighten it until it clicks at least once. It will most likely take a lot more torque to get it to click vs the one you have now. Also note how the rubber seal feels as it tightens on the reservoir, you should feel a lot more resistance, meaning it is sealing tighter as it should to let the pressure release work also as it should.
Happy Hump Day to you,
Dave

What is the kPa rating on the cap? My 2007 XK came with a 120 kPa (17 psi) cap. I bought a new coolant reservoir for preventive replacement, and the new reservoir came with a 200 kPa (29 psi) cap which seems like a crazy pressure setting.

You are right, if you buy a new reservoir (at least for 2010-up) it comes with that 200kPa Cap, I tossed mine in the bin and used the correct one for my VIN. No way am I going to stress an older XKR with those kind of pressures. Once I get all of those items replaced I may try it, but doubtful.
FYI, the one for your 4.2 appears to be XR850837 up to VIN # B25446
Cheers,
Dave

There's an active post here that shows the service manual specs for the 4.2 and 5.0
https://www.jaguarforums.com/forum/x...40-kpa-192460/
Neither mentions to 200 kPa. I have my doubts but is someone has a Jaguar service bulletin that changed the spec for the 5.0 from 140 to 200, could they please post here and on the linked thread to help others?
