I just bought a 94 legacy wagon with 86k miles for a snow car, and the water pump went out on my first trip up to the mountains. The mechanic suggests that I replace the timing belt (even though it was already done about 25k ago) and to replace The cam seals, tensioner belt, thermostat, and another seal "since they're already in there". I see the logig behind maximizing the labor, but am wndering if all these other repairs are overkill... Or if they are really a good idea while they are ripping my car apart to replace the water pump.. Any thoughts?
