2006 equinox overheating at idle

Resolved Question:

2006 equinox overheating at idle, fan is ok, thermostat replaced twice, flushed cooling system, bled air from system, seems to build up alot of pressure in system. When I bleed off the air in the system it seems to be ok for awhile. Haven't checked compression yet. I smell no coolant leaking, no coolant smell from exhaust, but the cooling system is drawing air pressure from somewhere. I have also changed the radiator cap.

do you ever need to add coolant?
has the engine ever been really hot?

tell me all you can
thanks

Yes I have added fluid only after letting air pressure off by using bleader screw at the top of the water pump, otherwise I lose no fluid. The engine has been hot enough to lose fluid thru the overflow. The temp warning light has come on but I pulled over immediately And shut off the engine. That only happened once.

ok
most times it only takes once of overheating to blow a head gasket or to crack an aluminum head..
but..lets try something here
sense you have worked on the cooling system,,it may still have some air in the system...lets not mess with the bleeder valve,,,lets bleed it this way

1,you need to remove the radiator/reservoir cap when engine is cold

2-start the engine and let it idle

3-turn the heater on high

4-keep coolant on hand and add it as needed...some coolant may gush out with the air,so be careful

5-keep doing this until the engine is at operating tempeture,the heater is hot and the coolant in the radiator settles down

6-then install the cap
