Overheating

Asked by Feb 12, 2017 at 10:56 PM about the 1999 Pontiac Grand Am 2 Dr GT1 Coupe

Question type: Maintenance & Repair

Got a 99 Grand am gt1 3400 series I've recently
done the head gaskets with new heads and had
the wrong antifreeze when I torn it down. I've blead
the cooling system replaced the water pump still
overheating and blowing bubbles thru the resivor
so the next couple of days I flushed the radiator
out and a lot of rusty looking fluid came out and it
seems to be running around 200-206 but still hear
bubbles running thru the system.

Use a block tester kit to see if the bubbles are exhaust, if so you may need to redo the head gaskets and have head or heads checked for cracks too. Bubbles is coolant is a symptom of head or head gasket damage, may have the gasket up side down or something.
