    How do you remove and install the thermostat on the 1991 Cadillac Fleetwood? Posted by Customer
    A:
    Start by draining the coolant below the thermostat housing. On some models, you may need to remove the upper air filter assembly. Then, remove the two bolts securing the upper thermostat housing to the lower housing and take off the upper housing. Next, remove the thermostat and O-ring from the lower housing.
