Ok so yesterday i changed the cambelt and water pump along with another radiator just in case it was a blockage. Ran out of time for the customer wanting the car back but i still had trouble bleeding the system. Not sure if this was due to time or not. I had a feeling it may be the heater matrix as on the fiesta and pumas the heater control valves cause the same problems once shot. So i disconnected the hoses from the heater and connected them to one another to bypass the heater circuit and it still didnt seem to bleed to well.

So anyway i drove it to the customer which is around 7 mile away and when i got there all the hoses were hot and the temp gauge didnt move once all the way and sat at half way nicely. since i stated this thread the engine has been running with an open thermostat with no temp issues but once i did the water pump i put the stat back in.

So until i have another hit at it in the week the question is...

has anyone experienced over heating problems through the heater matrix being the cause in the car?
