Well, it looks as if the PS pump is going out on my 2000 XK8, lots of grinding and groaning from the unit.

I'll want to replace the hoses while I'm at it. Looking here on the forum I see mention of a superceded part number and a straight vs. 90 degree fitting for the hose. Does anyone have the current part number for the high and low pressure hoses?

Also, I searched the archives for a "how to" on replacing the pump itself but didn't find anything. Is this a reasonable DIY project for a handy guy? It looks like the pump should slip out pretty easy but I thought it would be good to ask (my JTIS isn't with me here)...

Thanks!

 

This situation worked itself out nicely.

I was contemplating removing the pump myself and while looking things over noticed that 2 of the 3 bolts holding the pulley on were loose - I mean backed-out loose. Once I tightened these up the problem went away.

The pulley needs to be attached to the pump flange after the pump is installed and, depending on how you do the job, it is hard to get the proper torque on them.

I got lucky and saved $150 in parts and another $100 in labor.

 

Glad it worked out for ya. I remember seeing a few of those bolts come loose and always put loctite on them. I thought there was a service action for them but cannot seem to find the bulletin.

Enjoy.

 

Found it. Just a warning that it is not a recall and not covered by Jaguar anymore but the info in the bulletin pertains to your car.

 

That's awfully odd. Model years 1998 and 2001. Wonder what happened to 1999 and 2000. They must have NOS pumps from 1998 they discovered in 2001 and installed them.

 

Never noticed. I was always under the inpression it was 98 throough 01. Maybe that fella on the line moved away for a couple years and then came back.

 

Checking these bolts is a great DIY task. Easy on the XK8.

I'd suggest everyone check theirs if they have had front end engine work done, I suspect that's when mine were removed and reinstalled.

Thanks for finding the TSB.

 

Checked mine. Not "backing out loose" but not very tight...until now! Thanks for raising the issue and for the bulletin. Jac

PS- 13 MM if you are heading in to check yours. A deep-well socket worked for me.

 

Very timely indeed.

just noticed the same thing lots of groaning in the morning, with average temps of 25 degrees (f) in the morning when I leave....fill level was fine, apparently about the only thing I can do on these cars is check fluids I am finding out :-(.

Will check tonight

 

For those that have been there ... how are you getting the pulley to stay still during tightening?

It's not surprising that these back out, the bolts are only a half inch long and no signs of thread locker.
