It is located on the lower section of the motor, if you crawl under the car and remove the splash guard it should be visible. The AC compressor would be to your right, and to your left would be the starter. I believe there are two long bolts that hold it on, after you remove the bolts for misc wires. I've not been under mine recently, so Its a bit vague in me head.

No removal of the engine, and it isn't a hard job to do as long as you can get the car up on stands/ramps. It is at a wierd angle though so you will probably want to remove at least the radiator fan(s) to give yourself a bit more room...
