 RE: 2000 Ford Contour Overheating
The fluid in the expansion tank is fine and there is no antifreeze in the oil either. The easiest test for blown head gasket is a chemical block test. The head gasket seems to be fine. The fan works fine and the car does great on the open freeway with the a/c on hi but the car quickly overheats when going up a hill or putting additional load on the engine. It almost acts like there are air bubble in the system but I have bleed the system and it appears to be clean now.
Also, the transmission seems to be shifting strangely; going up hills I have noticed that the transmission wants to shift in to higher gears instead of lower gears. I wonder if this is overworking the engine and causing the problem. |
