Package Contents

Installation Guide
-
Safety First: Ensure the engine is completely cool and disconnect the battery.
-
Drain Coolant: Place a catch pan under the engine drain plug and drain the cooling system.
-
Locate Housing: Find the thermostat housing, typically where the main coolant hose from the heat exchanger meets the engine block.
-
Remove Old Thermostat: Carefully unbolt and remove the housing cover. Take note of the thermostat's orientation before lifting it out.
-
Clean Surfaces: Scrape off any old gasket material from both the housing and the engine mounting surface. Ensure both are clean and dry.
-
Install New Kit: Place the new thermostat into the housing in the correct orientation. Install the new gasket.
-
Reassemble: Reattach the housing cover and tighten the bolts to the manufacturer-specified torque, usually in a crisscross pattern.
-
Refill & Check: Reconnect the battery, refill the cooling system with the appropriate coolant, and run the engine to check for leaks and verify normal operating temperature.
