should be a single bolt in the center of the tensioner probly 15mm
Remove the old, damaged idler pulley and replace it with a new one.
Assuming you have a serpentine belt on that 3.3L engine, the tension on the alternator would be controlled by the idler (tension) pulley. The alternator is stationary.
To remove the pulley and serpentine belt assembly on a 1992 Toyota Camry, first, disconnect the negative battery terminal for safety. Then, use a wrench to relieve tension on the serpentine belt by rotating the tensioner pulley, allowing you to slip the belt off the pulleys. Next, remove any mounting bolts securing the pulley assembly to the engine, and carefully take out the pulley. Finally, replace the belt and reassemble in the reverse order.
You need a 1/2" ratchet or a Johnson bar. The idler pulley has a square 1/2" hole that the square on the ratchet will fit in and allow you to turn the pulley and relieve the tension.
put a wrench on the pulley side of the tensioner (15mm?) and turn. The pulley arm will move & loosen up the belt.
It probably has a tension release pully, not a bolt. The pully has no function except tension. Your repair manual probably has instructions on changing the belt and a photo of the small pulley. Mary
place appropriate size wrench (probably 15mm) on the bolt through the middle of the tensioner pulley and put clockwise tension on it, this will ease the tension on the belt enough to remove it.
To replace the serpentine belt on a 1992 Buick Riviera, first, ensure the engine is off and cool. Locate the serpentine belt routing diagram, usually found on a sticker under the hood, and use a wrench to relieve tension on the belt by rotating the tensioner pulley. Carefully remove the old belt, then thread the new belt according to the routing diagram. Finally, check the tension and ensure the belt is properly seated before starting the engine.
pull the tensioner to relieve the tension and slip the belt over the alternator pulley. The tensioner is a spring-loaded pulley below the alternator. The tensioner takes a special tool that fits into a square hole in the side of it. Or you can use an 18 mm socket on the tensioner's pulley bolt. Follow the decal near the right front corner of the engine compartment to route the new belt.
The AC idler pulley on a 1992 Subaru Loyale is located on the front of the engine, typically near the AC compressor. It is a small, round pulley that helps guide the serpentine belt that drives the AC system. To access it, you may need to remove any covers or components obstructing your view. Make sure to check the belt tension and alignment while inspecting the pulley.
Need to know which pulley.
