With the truck idling it's probably 45-50 degrees in the cab. The radiator temp is about 120 degrees. This is a 2004 Columbia. WHat can I do to stay warm? For now the cardboard on the grille may help. Also check to see that you didn't inadvertently activate the "fan override" switch on the dashboard. If the engine cooling fan is engaged in cold weather, the engine will have a hard time maintaining temp. For good heat you need at least 170 to 180 degrees water temp.

You may want to check your antifreeze. If it is low, it will be difficult for the truck to stay warm. Bumping the rpm's up will help keep the engine warmer. I had a fan clutch go out one time during a very cold winter. I nearly froze until I could get it fixed. It stayed on all the time. Brrrr! :?

It didn't take me long to learn a few things my first winter of driving.
1) Use the cruise control to bump up the idle to about 1000 rpm for heat. These diesels don't warm very well at low rpms. 2) If at all possible, when you park to get some rest, park with your tail to the wind. 3) Open the hood, and check the water lines to the heater core. They have a shutoff valve on the service and return lines, located near the engine block. Make sure those valves are open. The company shop mechs sometimes overlook that.
