My 2004 Mercury Mountaineer V8 has warm air coming out, but not hot. I replaced the thermostate last night. It is blowing just not hot.


the air from the blower will be the same temperature as the coolant temperature. If you want it hotter you may have to get a thermostat that opens at a higher temperature or close the air circulation vent so that only cabin air is heated.and not fresh freezing cold air from outside.

Overheating while driving my 2006 mercury mountaineer with 65000 miles on it. The coolant reservoir stays full but the radiator loses coolant but no puddles under the truck


If you are losing coolant but not leaking out, there are 2 other possibilities. Does it go intop the oilpan? Easy to verify by looking at dipstick. If no, then it is probably getting into the cylinders and going out the exhaust. Is the exhaust particularly moist? Causes for this would be a blown head gasket or cracked head. If you have more questions, please reply.

Car constantly overheating


if it has a viscous fan hub --replace it
if it has electric fans , check/ replace the coolant temperature sensor , fan relays or fan motors
have a compression test done to check for gasket or cracked head/s
over heating once a week is not constant so have the fault codes read to check for heated oxygen sensor problems altering the air / fuel mixture
