This related to my previous question about 1991 Camry overheat problem. After replaced head gasket, torque to spec, the car is still overheat. Timing to spec, super flush twice, both fans wrok. If I turn on the heater, then, temperature will return to normal...but, outside right now is 90+ degree...not very pleasent. Water pump/radiator/thermostat are new. It will overheat when I started driving the car about 10 minutes...if started and let it idle, then, it seems would not. It is a puzzle to me.

Remove the radiator cap when the motor's cold. The coolant should be at the top.
Make sure the hose is free of obstructions from the radiator to the coolant recovery tank.
If your radiator is not filled to the very top with coolant while cold try this little trick to see if you have a combustion leak in your cooling system. Remove the radiator cap. start the car and wait till the coolant circulates in the radiator. If the coolant starts to circulate replace the radiator cap with a Toyota pressure cap. It may be time for a new radiator if problems persist.
If you still have cooling problems have your cooling system pressure checked ant any independent garage or your Toyota dealer.
If the pressure bleeds off suspect the cylinder block and or cylinder head for flatness.
Supposedly, Toyota brand antifreeze has a stop leak additive built in, so I was told at my Toyota dealer.

You may have to go to a lower degree thermostat so it will open quicker. No heat generally means the heater core is shot, but if that was the case, the interior floor would be flooded with antifreeze. If you bought this car used, you might want to check that the previous owner didn't reroute the heater core hoses after the core went. It's an old "quick fix" trick that allows you to still drive around in the summertime. That's the way I "fixed" my 67 Cougar XR7-GT, which is only driven in the summer. Check the heater core hoses.

Did you make sure you purged all the air from your coolant?
