first look for the thermostat housing it should be at the end of the radiator hose connecting at the engine. remove the hose (after you drain fluid) the thermostat should be rigth there. remember the new one goes in the same way the old one came out. when reconnecting tighten equally not one side then the other or you will over tighten and break the housing. (est. time is about 15 min)
