I recently replaced the heater valve, didnot bother with a rebuild kit as that will probably fail sooner than a new valve. (You know how rebuilt things are.) This job is very simple; three hose clamps and one bolt. The difficulty for me was getting the cables back on. I found that by sticking my tongue out my right incisors and biting with moderate pressure helped.
