I have done a few of them, taking the facia off is tricky but once you do one, they arent that bad. You have to look and see if you have a seperate P/S cooler bolted to the front of your condenser, if you do, no further repair is nessicary, if you dont, you have to install a P/S cooler, new lines and blow out the stock cooler that is intigrated in the Condenser. I guess the passages are too small and can freeze under severe conditions.
