I have a dodge durango with a 5.9 liter. I live in colorado. When it is cold outside 30 degrees or below my truck takes forever to warm up. Some times it does not warm up at all. I usually start it for ten minutes before I drive to work. Then drive 20 more minutes to work and hardley ever does it show any signs of being warm. My truck has 60000 miles and runs fine. I was wondering if this happens to anyone else, and if not what might be wrong with mine.

Thanks for your response.

 

Mine seems to take awhile to heat up even while driving, but once it's warm it's pretty good. I know on my camaro when the coolant is low it won't heat up or takes forever, so i'd check your coolant level first. Could be a thermostat also. Or could just be the way these trucks are.
