05 equinox overheating -replaced head gaskets, thermostat, waterr pump, fan relays, EGR valve & all hoses,no air locks. heater gets hot like it should. what else could it be?

Clogged radiator or passage in the engine block of the cooling system ?

Try a cooling system flush.

I did flush the cooling system

does it get hot standing still or at highway speeds or both??

Standing still

Are you positive that the vehicle is overheating and not just a bad temp gauge saying it is overheating ? Also feel the top and bottom radiator hoses once vehicle has reached operating temp if both feel the same could just be a bad temp gauge. If bottom hose gets hot and the top hose stays lukewarm remove t- stat then reinstall hose to see if it overheats with out t-stat installed.

I have a Chevy equinox 2006 3.4 v6 I have a new thermostat

I Have A 2005 Chevy Equinox And It Is Overheating and Now I Be Needing Ah Boost For My Battery There Aren't Any Leaks From My Hoses

I have a 2005 equinox 3.4 engine is over heating a lot of people think head gasket but in these engines its a little different. DONT sell your car cheap the problem in a 3.1 ,3.4, up to prob a .9 in most cases are the intake manifold gaskets one or all 6 (if oil is mixing with water) it takes about a day to fix.

Well let me give you this to try. My name is Floyd and I replaced every damn thing. What it turned out to be well you know the hose that leads back down from the reservoir to right behind where the thermostat is at where the rubber tube goes on to that pipe it was completely clogged up. I mean hard mineral had clogged it up to the point where water was not going back out of the reservoir so it wasn't moving through the motor at all. The motor that I just took out when I looked at that pipe it was the same thing completely clogged up

Let me know if that pipe is clogged up are there so many people out there with the same symptoms I just wonder if it's that same thing with everybody. Everybody replaces their radiator their thermostat they flush their system they check their head gaskets an intake gaskets and that's all it was one little stopped up pipe

oh and it's also easy to check all you really need is a pair of pliers to take that clip off and you can just stick something down in there. If you can't get anything through it stopped up

2005 owner here....head gaskets were replaced last fall and a week ago it started overheating again. Apparently head gaskets are gone again
