06 chevy equinox
3.4 v6
82k

my car keeps overheating some how . I have changed the following

-theristat
-waterpump
-theristat sensor
-intake manifold gasket
-checked the pressure the pressure came up fine there for there is no problem with the head gaskets . we have checked each seperatly with the compression checker

however , i did notice that when the upper intake was shown there was alot of antifreeze in there like there was some leak but there was no sign of cracks or anything what so ever but we went ahead and changed the gaskets . There is no leaks in the hoses or anything . Im sure that some how i am still getting air in the motor because when the bleeder is opened there is nothing but air until you rev it it to 2000rpm . im not sure what is left . i just need some advice . remember i am a female i no a little but not to much about cars so try to explain without to much car lengo . thanks (=

Will the system hold pressure?

This could be as dumb as a bad radiator cap - unknown at the moment. Throwing parts at it is just wasting money. Why not get a pro do diagnose it instead of hit or miss on what were probably good parts?

Do a chamical sniffer test in the coolant to check for co in the coolant. More then likely headgaskets common on 3.4L

Headgaket may only leak under load or certain conditions. sniffer test works better.
