HI, Vehicle had no heat and was overheating, so we had the heater core flushed - twice. Didn't help. We changed the heater core and thermostat. Now vehicle is still overheating. What else do we check?

You first make sure that the cooling system is completely bled/purged of any trapped air, that can cause both symptoms, it that is done and you are sure you have purged all the air out then the head gasket would be most likely leaking.

What is causing overheating?

Could be air lock in system that needs bleeding or water pump not pumping water round!

Overheating and not throwing any heat

Have a flow test done on the radiator to check for blocked cores. Have a compression test done to check for head gasket and cracked head. Check that there is not an air lock in the cooling system as an air lock will cause overheating and no heater temperature.

1997 a4 se overheating.i have changed the thermostat and car is still overheating.cold air is coming from the drives perfectly is not coming would i diagnose the problem

Alot of time you have to bleed the cooling system after changing a thermostat it gets an air pocket in it look for a bleeder valve near or on the thermastat housing if so bleed it to get the air out.check the radiator and make sure its full because if you filled it up after changing the thermastat once the thermastat opened after the engine ran awhile well the cooling system needs refilled.
