Drain the coolant, remove the air intake, disconnect the battery, remove the alternator, power steering pump (I had to so I could access one stinking bolt), remove the water pump. Install in reverse order. It's a pretty easy job.

There's a couple of bleeding screws for the coolant system located on the upper radiator hoses that go to the water pump. Once you've filled up the system, just start the car, and open those bleeding screws. DO NOT TAKE THEM OUT. Just unscrew them some. When coolant starts to come out, close them, shut the car off, and check your coolant level. Add if necessary. Take car for a test drive for a while. If it runs hot, try bleeding again as there may be a trapped air pocket.
