Hi,
I'm replacing the headgasket on my 1993 granada 2.0 DOHC, as the coolant is over pressuring in the header tank.
I was wondering if there is a bimetallic strip in the heater that only allows water/coolant to flow through when the engine is warm or is it more likely to be blocked. I know it isn't passing through as I checked the temps of the inlet and outlet by touch and the outlet was still cold. Also I've tried to blow through the pipework and had nothing come out either.
So is it a new matrix or is there a heat controlled valve?
Cheers

Hi,
I have a Mk 3 Mondeo on an 03 plate. I noticed recently that the heater was constantly blowing cold air and am about to replace the thermostat as a matter of course. I found out last night though that the a/c compressor is running when the engine is on despite the a/c button being switched off. I removed the fuse in the battery fuse box and the compressor turned off, i swapped the relay with the horn one as they are the same to see if relay was at fault but it wasn't. Can any one help?
Cheers
