On 1170cc and 1237cc vehicles, the thermostat is located on the intake manifold, under the air cleaner nozzle, so you will first have to remove the air cleaner housing. On the CVCC and late model engines, it is located at the right rear of the distributor housing.
REMOVAL & INSTALLATION
- Place a clean drain pan under the radiator, remove the drain plug from the radiator and drain the coolant into the pan.
- Remove the thermostat cover-to-thermostat housing bolts, the cover, the gasket and the thermostat.
- Using a putty knife, clean the gasket mounting surfaces.
If the thermostat is equipped with a pin valve, be sure to install the thermostat with the pin facing upward.
- To install, use a new thermostat (if necessary), gasket, O-ring (if used), sealant (if necessary) and reverse the removal procedures. Always install the spring end of the thermostat facing the engine. Torque the thermostat cover-to-thermostat housing bolts to 7 ft. lbs. (1973-78) or 9 ft. lbs. (1979-83). Bleed the cooling system.
