Thermostat is located on the drivers side front of the engine, underneath. You will need to drain your antifreeze first of course. Disconnect the lower radiator hose from the thermostat housing, then remove the housing and thermostat. Take note of the direction the thermostat is oriented so you can put the new one in the same way. Install new thermostat, reinstall housing & lower rad hose. Check your owners manual or repair book for quantity of antifreeze to refill! It doesn't always want to take all of it at first. If you fall into the trap of not putting all of it in, you WILL overheat your engine & most likely blow a head gasket. Best procedure I've found is to elevate the front of the car & remove the bleed screw from the passengers side top of the radiator, then fill. That will help the air escape from the system. Air pockets in the system = hot spots and you dont want those.
