At first you were asking where the thermostat was located, then you say you replaced it already.

Are you doing this work?

Ask Your Own GMC Question
GMC Mechanic: Mike S., ASE Certified Technician replied 6 months ago

Yes

Was that yes an answer to have you checked the coolant or any leaks?

What radiator line is really hot?

Ask Your Own GMC Question
GMC Mechanic: Mike S., ASE Certified Technician replied 6 months ago

Is this just an Envoy or an Envoy XL? 4wd or rwd?

What sensor are you referring to?

Ask Your Own GMC Question
GMC Mechanic: Mike S., ASE Certified Technician replied 6 months ago

I assume this is the 4.2l engine.
