Underhood rubber degraded
While doing a basic tuneup recently, I noticed that a lot of rubber vacuum hoses are getting very brittle on my 25 year old XK6 engine. Also, a lot of the rubber boots that cover the connections to the various sensors are either missing or cracked.
Does anyone have a good vacuum diagram of the engine bay for a 1987 series III XJ6? I have in mind to replace every hose if I can. Also, what about all the rubber boots for the electrical. Is there a source for all replacement rubber bits which hopefully were common to many cars of the day? Even my battery terminal protective covers are cracked and ripped to pieces unfortunately. |
This might help
http://www.jag-lovers.org/xjlovers/info/XJ6Vacuum.pdf The injectors, coolant temp sensor, and thermotime switch all use garden variety connectors and boots. Google "Bosch injector boot" (or connector) I've used generic battery cable/post covers with good results. I think I got 'em at Moss Motors Cheers DD |
Sorry I just noticed this thread, but as a follow up to my other post in the smooth idle thread, I replaced all my vacuum hoses this past summer with silicon hoses and that was very helpful. i also found plenty of hoses which were obviously leaking (small holes or cracks from age). It was a pretty painless process. Have the diagram in Doug's link handy and start tracing and looking around the engine bay. You've have to remove a few things like the AFM and air cleaner to get at everything and most of it can be reached from the top, but I remember a few that were made much easier once I drove the car up on ramps and reached them from underneath. When I ran my new line I actually tried to run them all over the intake rather than under it for 2 reasons: 1.) easier to get to in the future should the need arise and 2.) I figured the further away from the engine block the better to minimize heat degradation. Let me know if you have any questions, and I can try to help out.

Thanks for the diagram link Doug,
Eric: Where did you get the silicon hoses? Are they superior to the rubber hoses I get and the auto supply store? |
