Just replaced the thermostat on a 2001 Firebird 3800 V6, which is actually very easy on these cars! Depending on the job, the 4th gen Firebird/Camaro is either very easy and simple or almost impossible to replace something on!
The OE thermostat is Stant and the gasket is already installed on the thermostat. The OEM thermostat also includes a jiggle pin.
The aftermarket thermostat that came out did not have that pin.
P0125 code kept popping up even after replacing the coolant temperature sensor, which was broken. It was replaced with an OEM ECT sensor, but the code came back! The coolant was also a few quarts low, though this particular cooling system on the F-body takes almost 3 gallons. I refilled with Peak 10x then used the Lisle coolant funnel to bleed.
The temperature gauge also behaved oddly, staying at cold until almost at operating temp, when it popped right to the middle. Now, it behaves in a more normal manner.
