first disconnect the battery - use a long breaker bar and socket to take tension off the tension pulley and at the same time remove the belt from the alternator pulley. disconnect the wires to the alternator make note of their positions. Then remove the 3 mounting bolts from the alternator.
Tensioner pulley below the alternator. Should be a 14 or 15mm socket and turn counter-clockwise.
there is an idle tension pulley on this motor that u either use a socket or just the head of a 3/8 drive rachet and pull
On my 94, the tension bar is between the passenger wheel well and the motor, towards the bottom. Use a wrench to lift the tension bar, and the belt should loosen up. On my 95 Corsica 2.2 4cyl, the tension pulley is DOWN and to the LEFT of the alternator pulley. The space in between the bolt on the pulley and the side of the engine compartment is to small for a socket. I used a box wrench and turned CLOCKWISE.
with a 9/16 socket and ratchet
a 19mm socket,breaker bar to tensioner and release tension by applying force towards the front of the vehicle. remove the belt from the alternator pulley. this will also be the last pulley for easier installation. it will save you a headache if you make yourself a diagram.
u need to relaese tension on the tension pulley. this is usually done with a long socket wrench handle. when u release tension and remove belt you then release tension on pulley until you have routed new belt . you then move tension pulley again until you can put belt on it, then release pulley and it will automatically provide correct tension
The first thing to do is disconnect the battery from the truck. Then you will need to lossen the belt off the enginge. In order to go that their should be a tension puller on the front that a simple rachet and socket will do. you turn that till it lossens the belt and slide it off the alternator. If it doesn't have tension pulley then the alternator has a bolt that you lossen it to get the belt off. After you get the belt off you need to dissconect the wires on the back of the alternator then you can take the two bolts out of the alternator and simple pull it off.
Hey there. There is a tensioner pulley just to the left of the alternator and a little below it.it has a bolt in the middle that if you put a large socket on it and crank it counterclockwise until it lifts upward and relieves tension on the belt you then (while you are still cranking on tension pulley ) just slide the belt off of the alternatoer and other pulleys . ..
with the correct type of socket and bar for easy access I had to use a crow bar as a socket wouldn't fit.
Are you talking about the "idler pulley"? They are quite simple to change. Loosen the serpentine belt by using a socket on the center of the tensioner pulley, slide the belt off the idler pulley, use a socket to pull the center bolt of the idler pulley and replace the pulley with a new one.
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.
