Ok...
On the 4cyl it is under the resonator on the front upper right side of the engine. You can't see it unless you move the resonator (the funny black flat plastic thing that sticks off of the intake tube).
If you loosen the two clamps on either side of where it connects to the tube you can gently pull the tip out of the rubber bushing and rotate it straight in the air to get ti out of the way.
You will see the "dog house" with two (I think) hoses connected. Drain part of your radiator to get the level below your thermo so it will be dry for reinstall.
There are two bolts that hold it in place.
Piece of cake.
Good luck,
