I have the Hayne's manual, and I was going to replace the water pump myself until I got to the part about removing half the engine (alternator, right-side engine mount, power-steering pump, engine drive belts, underside plastic protector, battery, etc.). My car has over 90K miles, and I would hate to pay someone to do this, but it seems too involved. Has anyone done this before? My car has been good to me, but should I just buck up and have this done?
