Here is a thought. Have you replaced the vehicles thermostat? If not, are you the original owner of the vehicle? I ask this because technically you can run the vehicle without a thermostat. Is there one in there and if there is it could be stuck open thus allowing the coolant from the engine to very get that warm.
Please consider a to help us answer more questions.
