If you have a serpentine belt (this belt is flat on one side and has 6 little "v's" on the other side about 1 1/4" wide) then there should be an "Idler" pulley that is internally spring loaded that puts the required tension on the belt, thus there is no "adjustment". But if this pulley is defective it must be replaced.
If yours has a single big "V" belt (about 1/2" wide) then the "Adjustment" usually consists of loosening the alternator and "biasing" it to tighten the belt then securing it again.

There is no adjustment of the pump. You can adjust belt tension, by loosing and adjusting tension with the bolts holding it in place, but that is all.

Hazard light on the 1991 Buick Regal is on the right side of the steering column. It is an unassuming black rectangle which slides up to activate.

You have to remove the steering wheel, and it requires special tools.
