FAQ for Thermostat Repair
Q: How do I install the Thermostat?
A:
You should install the thermostat into the housing, the gasket, and the coolant outlet, and install the bolts or the studs.
By Bob
GM Specialist
01/11/2022Q: How do I remove the Thermostat?
A:
You should drain the coolant until the radiator coolant level is below the thermostats. For the 5.7L only and 7.4L only, you should remove the bolts or studs, the coolant outlet, the thermostat from the housing, and the gasket, if needed, and clean the thermostat housing and the cooling outlet sealing surfaces.
