Hello, I wonder if anybody can explain these symptoms.
The car is a 1996 Citroen AX 1.0 Dimension petrol. After about half an hour of driving the temperature warning lamp lights up. While it is lit the heater blows cold air into the cabin. There is coolant in the expansion tank. Shorting out the radiator fan switch to leave the fan permanently on while driving does not improve the situation.
Is this behaviour consistent with a faulty thermostat? Or can you think of another cause?
David.
could be an air block, hence the cold air in the cabin, have you tried re-bleeding the cooling system ?
Thanks for the advice. I'll have a go. Any advice/suggestions for how to attach a header tank to the expansion tank?
David.
you should have bleed holes in one of the heater matrix pipes and i think there is one in the radiator itself at the top.
AX's are notorious for head gasket failure IIRC.
yep, all you get is a silly light telling your engines now fooked ;-)
if it wasn't before it will be now...
Thanks Reg! Bleeding the coolant did the trick! A great relief after reading some of the other suggestions.
David.
excellent Dave, many thanks for letting us know.
