Take the radiator inlet hose clamp off, followed by removing the radiator inlet hose from the Thermostat outlet pipe. Remove the thermostats outlet pipe bolt and Thermostat outlet pipe, discard the o-rings and remove the o-ring seals from thermostats outlet pipe. Remove the bolts and Thermostat Housing, and discard the seal ring, after getting rid of the o-rings. For installation, begin fitting a new seal ring and the Thermostat with the Thermostat outlet house into the engine, while ensuring that the Thermostat outlet bolts are fitted and then tightened to 20 nm (15 ft. Lbs.). Lubricate two new o-rings with coolant and insert them into the Thermostat outlet pipe, and the Thermostat outlet pipe and the Thermostat outlet pipe bolt, which should also need to be tightened to 20 nm (15ft. Lbs.). Next, install the radiator inlet hose to the Thermostat outlet pipe and fasten it with the radiator inlet hose clamp.
