What is the method for testing the operation of a thermostat on Oldsmobile Cutlass?

To check a thermostat, submerge the thermostat in water 25 degrees above its stamped temperature, usually 220 degrees for most GM engines. The valve should be fully open, then place it in water 10 degrees below the stamped temperature, typically 185 degrees, where the valve should close. If the thermostat functions correctly, reinstall it.

How to remove and replace a thermostat in a Oldsmobile Cutlass?

The thermostat is a valve in the engine that controls coolant temperature. To replace or test it, disconnect the negative battery cable and remove the air cleaner. Drain the coolant, but not from the engine. Disconnect the upper radiator hose and the smaller by-pass hose from the thermostat housing. Remove the housing bolts and lift the housing to reveal the thermostat. If there's a TVS switch, disconnect the vacuum hoses and unscrew the switch. Note the thermostat's position before removing it. Clean the old gasket from the housing and engine, then apply a bead of sealer around the engine's sealing surface. Place the thermostat and housing back, tighten the bolts, and reinstall the TVS switch and hoses. Reconnect the battery cable, refill the radiator with antifreeze and water, and run the engine until the upper radiator hose is hot, indicating the thermostat is open. Top up coolant if needed, then replace the radiator cap.
