1. Some models require you to remove the air cleaner assembly from the throttle body.
2. Some models with cruise control have a vacuum modulator attached to the thermostat housing with a bracket. It your vehicle is equipped as such, remove the bracket from the housing.
3. On the 4-cylinder engines, unbolt the water outlet from the thermostat housing, remove the outlet from the housing and lift the thermostat out of the housing. On all other models, unbolt the water outlet from the intake manifold, remove the outlet and lift the thermostat out of the manifold.

Just follow the top rad hose to the engine.It will end up at the thermostat housing.The thermostat is under the thing the upper rad hose goes to and once you have drained down the radiator some then just unbolt it and put in ther new thermostat[with a new gasket of course after you scrapped all the old gasket off].
