Question about 2003 GMC Sierra 1500
Posted by Anonymous on
There are a few things. engine overheating (or it thinks its overheating) and oil starvation those are the two main things. do you have electric fans or a fan clutch? if they are electric and are spinning real fast on a cold start up with ac off then your engine thinks it overheating.
