Ran into this problem? I just replaced my radiator and thermostat around 3 months ago. Now I cannot get my jeep to warm up unless its just sitting there but as soon as I start going down the road it cools all the way down and only blows cold air. No I didn't put thermostat in backwards and was wondering if replacing would help or not?

Also, what degree thermostat did you install? Where's the needle at on the gauge?

If it worked 3 months ago and not now, it's likely the thermostat failed. Did you install a "fail-safe" stat?

That's what it sounds like to me.
