Where The Top Radiator Hose Clamps Onto The Engine. Where It Clamps On Is Called A Thermostat Housing. Drain The Coolant Down Some From The Radiator. Remove The Top Hose End From The Thermostat Housing. Remove The Housing From Manifold, Remove Thermostat Install In Reverse Order. Be Sure To Install Thermostat In The Correct Direction & Be Careful That It Fits In The Groove In The Housing Or You Can Crack The Housing. Add The Coolant You Took Out And Get A Bottle Of ( water pump lubricant & rust inhibator) Small Plastic Bottle . Good Luck
