I have the vehicle listed above it is the SEL model. It has 3.0 V^ Duratec engine.
My problem is that car does not blow any heat at idle. Heat starts blowing only at higher rpm's, I have changed coolant, thermostat, coolant reservoir and cap as well as flushed heater core which had no rust in it. The car does not overheat at all. I did notice however that after cooling down I still have pressure in the coolant reservoir when opening the cap (it should not happen on the cold engine).
I was told that it could be ether cracked head or head gasket allowing cylinder pressure to get into the cooling system. There is no smoke out of the tail pipe and oil looks good. Another possibility is water pump impeller, but I really do not think so.
I need suggestions to try out and or help with illustrations to replace head gasket.
have the same problem?
