remove air intake duct. remove the thermostat housing bolts. lift the housing and then remove the thermostatt. if a gasket was used, remove all traces of the old one. most models will have a rubber ring around the thermostat so no gasket sealer is needed, unless there was a gasket there. slip the new thermostat in properly. position the housing cover on and tighten the bolts. DO NOT OVERTIGHTEN. it will crack and distort the housing if you do. loosen the bleeder screw on the housing and refill the system til air bubbles stop coming out. tighten bledder screw, replace cap. start engine and check for leaks.
no bleeding necessary, just run the engine and refill the radiator/reservoir back to capacity.
Thermostat, water pump, radiator cap, headgasket, low coolant.

the thermostat may need replacing
on top of engine, to the left side of the throttle body. where the top radiator hose leads to.
A thermostat can be stuck open or closed. If the engine runs to cool it is stuck open. If the engine is running hot it is stuck closed. If you don't have these problems you should'nt have to change it.
Follow the top radiator hose to where it connects to the motor. In this housing, is the thermostat.
