Friday the light came on my '99 Astro and the gauge dropped to 10 amps. I drove a few miles to the Interstate battery shop, they tested the battery (which was just replaced a month ago) and told me to push the emergency brake down one click to shut my headlights off and drive straight home (another four miles). I replaced my alternator on Saturday. Beautiful day in the fifties but as usual with owning a vehicle that has half of its engine under the dash, the procedure was not pleasant.
Others have posted that the job was easy even without removing additional parts???? I removed the air cleaner, the metal tube directly behind the air cleaner, the fan shroud, a small hose that dripped antifreeze that went into maybe the heater core :shrug: . Only then did I have a chance to get the alternator into a position where I could get to the wiring on the rear. As I turned the nut, the nut below the pigtail also turned which snapped the pigtail (which I replaced). I then used a socket on the outer nut and a small needle-nosed vise-grip (a narrow wrench would have worked much better) on the inner nut while holding it down on the concrete driveway with my left foot.The replacement alternator slipped back in with a little nudging. The gauge is now up to 15 1/2 amps.
I had a choice of a brand x replacement for $80, a re-manufactured factory unit for $110(lifetime) and a new factory unit for $130(lifetime). I chose the middle unit. Did I make the right choice? :think:
