Would like to change the alternator V belt on a 1991 Mazda Protege and the serpentine belt must come off first. Looks like the AC pulley is where this loosens. Can anyone tell me how to do this?
Thanks,
Ed
You've got to loosen the mounting bolt first, which is located behind the pulley itself. Rotate the pulley until the large opening allows access to the bolt, then use a socket with a narrow head to turn the bolt, just until it starts to turn freely.
Then there are two locknuts on the adjuster; one right near the mounting bolt and one underneath towards the middle of the pump. Loosen both of those, and then *finally* you'll be able to turn the adjusting bolt that faces the front end of the car on the end of the adjuster arm. It's a long bolt; just keep turning that thing until the belt loosens enough to come off the pulley.
Best of luck!
By the way, I forgot to mention at the start that the adjustment for the PS/AC belt is on the power steering pump,not the air conditioning compressor.
Technically, it's not a serpentine belt, either; on that year they're just plain ordinary fan belts. :)
