I have 2005 ford freestyle SEL
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 RPMs,
I have changed coolant, thermostat, coolant reservoir and cap as well as flused heater core which had no rust in it.
The car does not overheat at all.
I did notice however that after cooling down I stil 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 eather cracked head or headgasket allowing cylindar pressure to get into the cooling system. There is no smoke out of the tail pipe and oil looks good.
Another posibility is water pump impeller but I really dont think so.
I need suggestions to try out and or help with illustrations to replace head gasket
have the same problem?
