2002 Pontiac Grand Prix Repair Question
Pontiac grand prix overheating
sealer is always a bad idea. it clogs the radiator and needs to be acid flushed to get it out.
from overheating, you need a leak down test to confirm you did not damage the head gaskets.
I never used a sealer at all and to flush it I used prestone im assuming the gunk in there was blocking the problem so it didnt overheat now that its out it overheats again . maybe a water pump?
Also there is coolant in the oil so I dont think its a blown head
if there is coolant in the oil as you said, then it does have a blown head gasket.
the gunk must be pressure flushed with acid to rid it of the stuff and re gain flow.
Any other suggestions ?
not until those are confirmed, especially the fact that you confirmed the head gasket is bad with coolant in the oil.
Im sorry I meant there is NO coolant in the oil
we are still at the radiator needing to be flushed out for flow with a pressure treatment.
There is no coolant in the oil I meant
same answer as above.
