I have searched the site for info on replacing the w/p on the 75 300D and have found none that gives me enough confidence to go ahead and do it myself. I recently purchased this car and would love to be able to do such things but would like a little input.

The car has a non-functioning a/c unit and mount in the way of the w/p. Looking at it, it seems pretty strait forward except for the fan assembly and a/c mount. Would it be a good time to replace the little coolant hose between the thermostat and pump? Please provide insite on the process. I assume a good parts shipper would send all gaskets and rubbers.
