When shutting off my '95 XJS, the electric fan continues to run, which is normal, but it's supposed to eventually shut off. On a few occasions it simply hasn't. This doesn't always happened, but we discovered that this was going on when it eventually ran the battery down. It's happened a few times lately.

Obviuosly there's some kind of faulty sensor or relay. Does anyone know where it's located and how to replace it?

(We don't have a Jag dealer around here.)

Many thanks.

If you don't have to keep it original, flexalite has an after market temperature controller i have used on vehicles for our business. You bolt it down, after making sure you have a good ground connection, supply fused 12v to one side of the fan, the other fan terminal goes to a terminal on the controller. there is a thin copper tube which is inserted into the upper radiator hose. you turn a potentiometer to make the fan come on as soon as you reach slightly higher than normal operating temp. there are terminals for a/c relay (also available from flexalite) and a manual override switch.

all hardware comes with the controller, it took about 20 minutes to install, never had problem with one of these. The whole thing cost $55. including the a/c relay.

It's only normal to run on if gthe engine is very hot, where is around here? At this time of year -even in LA- it should not normally come on! I would suspect the thermo switch but get some kind of temprature gauge or pyrometer and see what the eng temp really is. Jaguar affectionado and etc.

I believe this problem is dealt with in the Kirby Palm book available for free for all to down load @ Jaglovers in the "our books section".
I believe it is a relay on the driver side inner front fender. There is also a mod described in there ( that I have done )that re starts the fan if the temp rises again to further help cool the engine and components in tha engine bay.
Good luck, Art
