This is a really easy job to do. Here's a writeup with pics on how to do it.

My only advice is to:

1) Do it while the engine is cold.

2) Note the placement of the parts when you're taking it out and replace exactly in order.

3) When finished start the car up and let it get up to operating temp to make sure it's not leaking.
