Follow the upper radiator hose from where it leaves the radiator to where it enters the engine block on top of the engine. This is where the thermostat will be located. You'll need to remove the hose and the housing (2-3 bolts) that covers the thermostat to replace it. Make sure to get a new gasket when you put the housing back on.
