I have 200 impala and it’s over heating. I have already changed the gaskets, re-surface the heads, replace the radiator, new fans, new water pump, thermostatic and burp the system. The car is still overheating. Can somebody please help before I drive this car off a cliff?

. Check the Engine Coolant Temperature (ECT) Switch.

. Check the radiator fan relay.

. Check all under hood and under dash fuses with a test light or multimeter.

. Test/replace the radiator cap (OEM only).
