2001 sunfire air in system

Asked by May 20, 2016 at 01:17 AM about the 2001 Pontiac Sunfire SE Coupe

Question type: Maintenance & Repair

My 2001 sunfire 2.2L keeps over heating. I think it
has air in the Colling system. I have replaced the
head gasket, had head milled, new head bolts and
studs, new water pump, thermostat i open the
bleeder valve and does not good squeeze hoses
and fill up tank when coolant runs out if valve
constantly close valve and car stikk gets hot. Will
run fine for a while but will overheat eventually. Or
when you get on it can't figure it out.

Some cooling systems are very hard to get the air out. Some shops have a machine to aid in purging the air out of cooling systems. May want to check into that. Also first try leaving the radiator cap off or reservoir tank cap off and run the car until the thermostat opens up. Fill as necessary until full.

Check that the electric cooling fan is operating. could be the fan or the thermal couple sensor
