Cooling fan
« on: March 07, 2007, 23:16:01 »
My cooling fan is on all the time, I have replaced the switch, believing the original was at fault, but still on all the time, has anyone else had same/similar problem, if yes, what was the fix?

Technical Tip.
Operating a vehicle with just one tyre under inflated by 20% (8PSI) can reduce the life of the tyre by up to 9500 miles, and can increase the vehicles fuel consumption by as much as 4%.

What type of system is the electric fan, also is the temp guage reading high all the time

I presume you have tested the opening temp on the switch sensor

Not every problem can be solved with duct tape, and it's exactly for those situations we have WD 40

I'm not certain what fan it is, how do I tell?
No, the temp gauge is fine now, since I replaced the gasket (front of cylinder head).
I have looked at the circuit diagram in my old haynes manual, having replaced the switch, and NOW understanding how the switch works, I believe it could be a relay, I pulled off the LH kickboard/facia to discover a set of relays, but do not know which, I suppose process of elimination, and a bit of shuffling them about to see if one of them is knackered, or one of the techie guys on Mud-Club could state which to look at, Immediately under the facia, their are 4 relays. 1 green & 3yellow, with a bit of wrist manipulation, I also see a couple of others stashed out of the way, not having a good relay to play about with, I am a tad worried if I [!Expletive Deleted!] something else up by taking a good relay out of its socket and insert a duff one.

Advice please  :oops:  :?
