Had an odd experience replacing the water pump on my XJR.

Purchased new (aftermarket) pump from Coventry West. On casual inspection it was a good match. After installation, however, it would not turn! I discovered this on engine start-up when the belt screeched and smoked on the *non-rotating* pulley. Gahhh!

On removal and closer inspection by standing the two pumps side-by-side I saw that the impellor on the new pump was proud of the pump body by about 1/8" more than the old pump. This caused the impellor to jam against the pump housing when the pump was bolted up.

So there's a little something for everyone to check if a water pump replacement is in the cards. Can't say I've ever come across it before but there's always a first time.

A water pump job isn't the worst thing in the world on one of these cars but it's not the type of thing you really wanna do twice, either :-)

Credit to Coventry West for providing a replacement in record time. Good guys there.

Cheers

My pump is making noise and I was just about to purchase one from the same place. thank you, I will check and recheck before installation.

 

Doug, thanks for the tip. Good to know about the water pump, and Coventry West.

 

Just removed my XJR's Water pump . Ordered a replacement from Gaudin supplied VIN # Recieved a metal inserted impeller pump { best way to describe it} Does not fit Seems I saw a mention of not buying metal one plus another post saying get the metal one .
Little confusing .
Will see how Gaudin responds to issue.

Correction ,
I purchased the replacement water pump from JAGUAR PARTS CENTER not Gaudin as noted .

 

Help, contacted Coventry West they say " sold 100's of pumps all same.
Have removed old water pump and can see large O-ring in place .
Do I insert new raised lip water pump in opening leaving O-ring in place . Does the new plastic gasket cover opening . IS THIS A PRESS FIT ,se do not want to force new pump in .

If that's a 2001 you are asking about, you will have more assistance if you address the XJ (X308) forum.
