Citroen Xantia temperature warning light - showbiz_28
AAAAAAAAGH!!
I've recently bought a Xantia. All is well with the car with the exception of the little red high temperature warning light which is on permanetly, and as such acompanied by the STOP warning light.

I'm not sure what is causing this, but if I let the car idle for too long it starts to boil up. The other worrying factor is that the fans don't cut in at all.

I have a pretty good grasp of what is supposd to happen with temp sensors etc, but not sure if it would be the fan sensor on the rad, or the sender on the back of the thermostat causing the problem?
Apparently there is another sensor on the head????

Is it liklely that the fault lies with the rad or the thermostat sensor?

Any help gratefully recieved.

Cheers

Is this the petrol 1.8 16 valve with air con by any chance?

I had a similar problem with one that I had for a short while. There was a little box of tricks that had something to do with the cooling system. It sat behind the NS headlight and these could suffer in a minor accident. Mine needed replacing at the cost of £40 or so from a Citroen specialist and the problem went.

Could be that. There are some relays that control the fans on the aircon model and these can give up, might just be bad contacts though. Don't leave it or you'll end up with a blown head gasket.

Hi H,

I have noticed he box of tricks as you call it, and on closer inspection the car does show signs of a very minor front ender.
I'll probably go with the cheaper options first and see what goes.

Thanks for your help
