  • Ford Model: Mondeo 2.0 TDCi 130bhp

Posted 01 December 2010 - 10:18 PM

I have a 2.0 TDCi 130bhp Mondeo, 2004. Engine seems to be cooling but doesnt circulate water,hence bottom part of radiator is cold, top pipe is warm. Have changed water pump and thermostat, blowing warm in the car, but not hot. Temp gauge doesnt read until doing approx 80mph on motorway, then temp gauge drops when slow down. Does not move on tick over. Header tank stays cold. Anybody got any suggestions please?

Have something to contribute?

Have you checked that the radiator is circulating correctly? You will have to backflush it to be sure. Strange that it does not seem to be overheating which is what you would normally expect with a blocked rad. Try taking the themostat out altogether and see if the water starts to circulate properly as the thermostat could be jammed even if it is new. Make sure as well that the water pump is actually operating as well. Hope this helps
