WHen idling, the needle on the temp gauge sits in the middle of the gauge, covering the red light, after a while the fan may come on for a few minutes then cut out, all very well and good.

when driving, the needle sits just to the right of the light, and the fan tends to come on either for long periods of time, or click rapidly on and off manically, or just flip on for a few seconds. this doesnt seem right to me...

added to this is the oprblem i have had for some time, of the needle and light combo - needle scooting to the top, usually after 50+ miles, but not always, then coming down after a little while.

garage has been unable to detect any overheating, and say fan comes on at right time etc, but then they have only idled it, and not driven it up the A1...

any thoughts or anything i should be worried about?

Are we to assume the engine is a Wasserboxer ?

IF it is.......

Try replacing the Header tank cap ( the one inside engine compartment NOT behind the rear flap ) if you wish to do something positive before getting involved with any thing expensive.

sticking thermostat or poss just poor earthing/conections in/on/for the clockes etc if it happens very quickly....

Big electric short outs cause the temp gauge to rise very rapidly, sounds like your radiator thermo switch, which controls your fan is malfunctioning. The gauge is a separate circuit to the fan, so a high reading doesnt have to mean the fan will come on, unless the thermoswitch tells it to.

Sorry to hear that you're still having problems with your cooling system. Keep an eye on the techie weekend thread in members only, highly recommended. Hope you get it sorted.

cheers guys - have just ordered parts from brickwerks!

can anyone tell me how to fit the thermo-switch, at the risk of sounding dumb! i would ask keith to show me, but inconsiderately he has gone to scotland!

thanks again

you can normally tell if the cap is faulty, bad pressurisation, no whoosh sound when you take the cap off etc etc ..
