Replacing oil cooler hose
#21
Very helpful thread, thanks! I'm ordering the feeder hose for my 2002 XJR tomorrow and it looks like I don't need anything else, right?
They said it would take 2 days to arrive so maybe I'll change out the hose this weekend. It's been weeping for a while so I'm just going to get it done now....thanks again for the thread.

Jeroen, the oil cooler pipes are indeed push fit into the block, once you remove the torx bolt and double clamp plate, a quick squirt of WD40 then gently wiggle the hoses back and forth. They should pop out easily.
Dropping the engine oil prior to this work, installing a new oil filter and engine oil once the new hoses are installed is a job called Done

The new part came in the next day, both O-rings pre-installed. I've got it apart except for the connection to the sump. Even with the fan shroud out there's no way to "see" it, but I can feel around and get the bolt out; that's what I'm about to do now. It's disconnected from the oil cooler and very little oil drained out (I didn't drain the oil because I JUST changed it 2 days ago).
Question -- On the off chance anyone answers this in the next 30 minutes before I'm putting it back together.....do I need to lubricate the O-rings with oil like you do the gasket on an oil filter?
Update -- I'm feeling rather defeated! I've done much more difficult repairs than this but this one is a bummer. The new hose seemed to "snap" into place nicely at the sump and I replaced the little plate and screw. But, now there is a leak at the connection point where the hoses go into the sump; the hardest place to access! I now have to take everything completely apart again and try to figure out if it's the new hose or the return hose that I didn't replace that is leaking. I'm exhausted and don't feel like taking it all apart again now, but the leak is steady enough that I really don't want to drive the car until it's repaired. If anyone has an idea what is causing this leak please let me know. Thanks.

The feed hose was leaking at the crimped connection from the metal to flexible part of the line. I had to replace or repair the whole thing and got a good price on a new one. After installing it the connection at the sump for the RETURN hose started leaking! So much fun.
My wife is picking up the 2 O-rings for that hose from the Jaguar dealer on her way home from work. I guess I'll take the return hose off, replace the O-rings and put it back on...hopefully that'll stop the leak.
Epilogue: Apparently when I loosened the connector at the sump to install the new feed line it wiggled the return line connection and the 18 year old O-ring lost its grip. I took the line off and replaced both O-rings. It all seems good now.
