Located in a removable housing at the engine end of the upper radiator hose
Drain about 1 gallon of coolant from the radiator
Disconnect Upper Radiator Hose
Two bolts to remove the metal housing
Note how thermostat is installed in housing, pull the thermostat out
Clean both surfaces
Replace thermostat as it was and gasket, usually these come with an o ring gasket on the thermostat (i also like to use a little black rtv on the edges of the housing to make sure it seals)
Replace housing
Important!
Refill coolant slowly to prevent an air lock, follow the coolant bleed procedure in your owners manual, there are two bleeder screws you need to open to let the air out
Start engine and look for leaks
Run engine to normal operating temperature with heater on
Re-check coolant level
