How to Troubleshoot, Replace, and Maintain a Thermostat on Chevrolet Express and GMC Savana?

When replacing the thermostat it is important to check the coolant level, drive belt tension, and temperature gauge (or light) operation. The housing cover should be reattached and tightened to the proper torque specifications. The hose should be reattached and the hose clamp should be tightened securely. Finally, start the engine and allow it to reach a normal operating temperature to check for leaks.
