It was much easier for me to remove the radiator before I removed the steering gear pump. The above comment about being a first timer is true because there are attachment points which are indeed tricky. I pulled the assembly off before I removed the pump. Unless you have a puller to remove the pulley I would let a good mechanic tackle the job. I ordered a rebuilt unit from the site above and the instructions to get your core charge back are very direct. You can remove The AC ( if equipped) condensor and fan as one unit-just mark your wires from the harness but remember that the AC system may be charged It's not too bad if you take your time. While in there I replaced the front crankshaft seal which was leaking.
There are other parts which are easy to get to when you perform this procedure not to mention giving things a good cleaning.
