I'm in norther PA right now and it's COLD!!!
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.

i had the same problem on my mack last year, and like the previous poster wrote, my heat was turned off. I'm not real technical, so i'm not sure of the correct terminology here, but under the hood there is a valve that turns your heat on and off, that very well could be your problem. I'm not going to say much more, like i said i'm not a mechanic, so i'll stop before i say something stupid

![]() I found out that I can bump the idle up by hitting the RSM/ACC lever on the cruise control. 1K rpms gets it working!!
