    A:
    1. Remove the air filter housing and air intake duct. 2. Drain the cooling system and save the coolant if it is in good condition. 3. Remove the coolant reservoir. 4. Remove the thermostat housing cover, which depends on the engine. 5. Replace the housing cover if the large fitting that mates with the hose is deteriorated. 6. Remove the old gasket material or sealant from the housing cover. 7. Install a new rubber seal over the thermostat. 8. Install the new thermostat with the spring end directed into the engine. 9. Reattach and tighten the housing cover to the proper torque specifications. 10. Reattach the hose and tighten the hose clamp securely. 11. Install all components that were removed for access. 12. Refill the cooling system. 13. Start the engine and allow it to reach normal operating temperature to check for leaks and proper thermostat operation.
