You need to put something in front of radiator like cardboard make sure you leave some radiator exposed (forgot percentage).

Also some members remove their fan for the winter.

Your blend door mite be broke or stuck. Actuator for blend door mite be working right.

Thanks guys,

i guess i will have a look at the door first, where is the blend door located? also the coolant heats up just fine and in 9 years i have never had to put cardboard in front of it.

Sounds like you need a new thermostat. I don't know where you are located, but you may try plugging in at night.
