    For Some Reason I Have Noticed Over The Last Few Days My Engine Temp Has Been Running A Good Bit Colder Than Usual... I Am Wondering If Anybody Has An Answer As To Why .....normally Running On The Interstate At Around 80 My Temp Is Around 185 Give Or Take A Few ...lately It Has Dropped To Around 170 Or 165 And When I Stop And Let It Idle The Temp Dropps Even More Like Around 150 .....i Am Not Sure If This Is A Problem Or Not But I Think It Is Unusual Being I Am In Louisiana And It Is In The High 90s Everyday Right Now..... Any Advice Or Opinions Would Be Appreciated..... Thanx

    You're thermostat is stuck open. It's no big deal, mine did the same thing and it wouldn't hardly warm up completely. But hey, it's a lot better than having it stick shut.:doah:

    Go to a Dodge dealer or Cummins dealer and pick up a thermostat, there is a new one anyway that has a larger mouth which allows for better cool down under load. The thermos from an autoparts store look like they belong in a small car.
