First make certain the
Radiator draincock is not open while the system is at a high temperature and pressure to prevent severe burns from coolant. Make sure the radiator coolant doesn't go past the thermostat housing and don't forget to save clean coolant by placing it into a suitable container. Always use the 6094 special clamp or the HPC-20 Snap-On tool, along with safety glasses, whenever installing constant tension hose clamps. Observe that original equipment constant tension clamps carry a label on the tongue and when replacing, only a corresponding clamp should be selected. Release the upper radiator hose and heater hose found at the thermostat housing, unhook the wiring from the engine
Coolant Temperature Sensor and take off the thermostat housing bolts, thermostat housing, gasket and thermostat. After that, discard the old gasket. Before fixing the new thermostat with the pellet toward the engine, make sure to clean the gasket mating surfaces and set the arrow and air bleed hole correctly in place on the engine cylinder's recess. Slide in the new gasket and thermostat housing, then tighten the housing bolts, making sure to do it evenly so as not to crack the case and use a torque wrench to tighten to 20 Nm (15 ft. lbs.). Hook the hoses onto the thermostat housing and plug the electrical connector back into the coolant temperature sensor. Either remove the radiator draincock or tighten it and fill the cooling system properly with the prescribed coolant mix. After you have done everything, start the engine and also inspect it for leaks.
