Im an autotard as well, but im learning. Probably the most important thing i've learned is to have a good set of tools, the right tools, and a nice place to work. From what ive seen, the ic pump doesnt seem like too hard of a job, But I didn't even know where the pump was located until a falling rock tore into my front bumper and made a hole right where the pump was. There are a few write ups on the site for both the pump and heat exchanger. Once my HE arrives I will be installing it along with the pump and I may do a detailed write up for dummies, with pictures.

This thread has many write-ups, including the IC Pump and HE.
