Follow the upper radiator hose to the engine. It will end at the t-stat housing. Drain the radiator, remove the hose, remove the thermostat housing, pay attention to how the thermostat is positioned and remove it clean the old gasket material, replace the new thermostat facing the same direction, and reverse the procedure.
