Hi There Jaguar Group! I drove home on Tuesday and had smoke coming from underneath, and parked to find a trail of oil drops, and lake of oil underneath my 2004 Jaguar XKR. Read the forums, and bought the left, oil cooler inlet hose. Took everything apart and it looks like it rests on the anti-roll bar, and I just replaced both bushings because it was clunking terribly! I think that the oil coolant hose was being jacked by the anti-roll bar. Anyways, I have the new hose, but cannot see or seem to find the correct size socket - does anybody know what size (the x-shaped oil coolant hose retainer). Thanks! Dave

From memory, it is just a normal screw, say 12 or 13mm. I used a socket and a short extension with a 3/8" breaker bar, nothing special. A mechanic's mirror can help you get a good look. More impressive than difficult, really. This is for the x-brace holding the 2 lines to the engine block. As pointed out before, consider replacing the 4 lines (I know, $$) as they all see the same pressure and likely aged the same.
Best of luck, keep us posted.

How much stuff needs to come out for replacing these lines on a coupe? I don’t know if mine are still the original ones, but they do have the newer style ferrule/crimp.

Caveat: When you put the lines back on the block, be sure to figure out a way to push them in properly as it is a bit hard with the new o-ring. If you use the bolt to pressure the x-brace for the same purpose, you will get into the conundrum of the cheap hard steel screw into the soft Aluminum block and, or so I hear from a friend (ahem!), strip the threads.
Best of luck, keep us posted.

Using the bolt to pull in the hoses gives you zero "feel" for what is happening, and disaster awaits.

My high pressure hose burst recently in the middle of the expressway at 75 mph In about 10 seconds and 500 feet before I got to the side of the road, the crankcase was emptied and the bottom of the car entirely encased in oil. The line burst not at the ferrule/connector, but in the middle of the rubber section, cracking in half. High pressure means high pressure. Never so glad to see the "red flash of death" on the dash (Low Oil Pressure!), as it probably saved the car. No damage since that I can detect in the past few weeks. Moral of the story is to check the hoses if you want - simply look to the sides of the radiator for leaks/squeeze the hoses to see if still flexible - but the reality is to get new hoses no matter what, if they are more than 10 years old or even sooner if driven in high heat. The risk is high. I was on life support at 17 years. OEM hoses are available on line for about $450, and you will have the luxury of doing them yourself, if desired. Not something I wanted to do with the car bathed in oil, so $1000 out the door.
