3.8L common problems
There is a temp sensor in the passenger side of the intake mainfold that tends to leak after 100,000 miles. The dexcool eats away at the plastic. It is a common problem for antifreeze to be lost there and the cause of an engine to not start. GM has released an redesigned intake to solve the problem.
