follow the top radiator hose to the engine,a hose clamp is holding the hose to the water outlet,take out the two bolts holding the outlet to the engine,pull the hose up, the thermostat is sitting down inside just pull it out,when you put it back together make sure the thermostat is down where it belongs and the housing and engine where the gasket go are clean or you will break the housing when you tighten it down.
