Do the cooling fans come on ? Your vehicle should have two fans controlled by The PCM - engine computer energizing three different relay's for low and high speed .

Did you replace the thermostat as well? That could be your problem. Also make sure your radiator and reservoir are full.

Overheated, changed water pump and thermostat. Overheated again within a week.

Check the cooling fan operation. It's also possible that you have a blown head gasket.

I just changed the water pump, thermostat, and flushed the heater core. I ran the car for a while with the surge tank cover off and kept filling it. As soon as I got on th e-way it overheated.

The surge tank should only have a little water in it, not full. I hope you didn't overfill it, this can cause your problem, but I would look at the radiator and make sure it is not plugged and your cooling fans, make sure they are running as well. Then last but not least your water pump may be bad even though you changed it, check for good flow through the radiator, if flow is good and strong then check the fans. You have already done most of what can be done, make sure the thermostat is not in backwards, in fact take it out and see if the car runs cooler, this will help pinpoint the issue also.

I have a 2005 chevy equinox Ls and have changed the thermostat,flushed the radiator,changed the spark plugs and wires, and refilled the radiator with coolant. and did a oil change. and it has been...

possible blown head gasket. Put in gear with your foot on the brake and rev up to see if there is vapor coming out the exhaust. Also remove radiator cap and run engine to see if bubbles come out of the radiator. Either of these would indicate a blown head gasket or possibly a cracked head.

I have a 2005 Chevy Equinox, keeps over heating. We changed the thermostat, then the water pump, but it is still running hot. No leaks and no check engine light. Not sure what else the problem can be.

These trucks are bad about developing an air lock in the coolant system. Be sure that there is no air in the system after sealing. This can be done by using the bleeder on the top of the engine near the water jacket. Hope this helps. good luck.
