On the back of the engine block next to the coil packs. Best way I found to remove without snapping it is to get a long prybar up under the metal hold down bracket... soak the hell out of it with penetrating oil... apply light pressure to the prybar and twist the sensor back and forth (holding the bracket) a bunch of times to work it out slowly. If you just pull or pry down hard it will snap off and now you have a *BIG* problem on your hands. (it's only plastic and fragile as hell, and the more miles you have the more it will have layers of varnish built up on the inside and be more reluctant to budge) Patience is the key. Stupid design if you ask me. HOPE THIS HELPS!
Rear of the engine block.
its the sensor in the tube going in to the throttle body from the air cleaner
it is next to the coils at the rear of the engin between the tranmission and the engin
Start at the radiator and follow the upper rad hose to the engine. The hose connects to the thermostat housing. The thermostat is located in this housing.
