what else can it be?
my 96 impala keep running hot! i changed the water pump thermastat and temp sens on 1996 Chevrolet Impala SS
Any oil in your coolant? How well do your cooling fans come on when the Chevy gets hot? If there is oil in the coolant, could be a bad head gasket, if the coolant ever got thick like GM dexcool does, then your radiator could be clogged.
I hope it not the h.g. There's no oil in coolant I pray its the radiator! But thanks for the feedback
