engine heat

Remove the thermostat and check it. You may have gotten a bad one. If it opens too soon, the engine won't warm up.

I thought that was a possibility. Wanted to do that as a last resort. What are the chances it is a bad one? Is there anyway to tell from just looking at the thermostat that it is defective?

To test a thermostat, you need to boil it in water with a thermometer that will show high temps. By doing that, you will see when the thermostat opens. If you go to the home page under do it yourself, there is a section that describes how to do it.

I'll give it a try. Thanks.

Let me know what you find.

For the past couple mornings its been around 20 degrees. I've let my truck idle for about 5 minutes before going to work and its been warming up to appropriate temp while blowing hot air into the cab. I don't know why it fixed itself but let's hope it continues to run properly. Thanks for your help.

The thermostat may have been stuck. Let me know if things change.

Have a great Christmas!
