The thead on the pully bolt is reversed. Pulling on it with a spanner in the anticlockwise direction will lock up the thread and reduce tension on the pully arm but its spring loaded so you need a friend to help or one hand free to slip the belt off while your holding the pulley back.
To replace the belt tensioner on a v6 commodore you start by removing the fan belt by using a 18mm spanner and rotating the pulley assembly anti clockwise. Undo the bolt by holding the tensioner pulley on and use the 18mm spanner to turn bolt clockwise to undo threaded. Place new pulley onto shaft, drop some Loctite onto bolt and screw in. Rotate pulley anti clockwise and put the fan belt back in.
the vt commodore has a automatic tensioner. you will need a 15mm socket and breaker bar or spanner. it is a left hand thread so if you apply pressure counter clockwise you will move the tensioner and be able to slip the belt on. that is if your talking about the v6 engine.
you dont,the tensioner tightens the belt up.if belt sqeals get new belt or tensioner! on 3.1v6,
no, unless the tensioner is bad, other than that just the belt.
first make a drawing of the routing of the belt then loosen tensioner remove the old belt install the new belt as per your drawing and release the tensioner after you have made sure the belt is tracking as it should on the pulleys nothing to it good luck
by loosening the belt tensioner
To replace the timing belt tensioner on a 1987 to 1990 Chevrolet Celebrity V6: 1. Use a 3/8" breaker bar to release the belt tension, move the belt out of the way. 2. Remove the single bolt out of the center of the fixed end of the tensioner. The belt tensioner will now come off. 3. Install the replacement tensioner and put the belt back on.
you do not need a tool to tension pully belt if belt is loose, belt needs replacing tensioner works automatically
The GrandAm has an automatic belt tensioner built in. Loosening the belt manually would not be feasable without the removal of the belt tensioner at which point the belt would no longer fit.
Loosen the tensioner pulley. Put the fan belt around the pulleys. Pry the tensioner pulley to the right until the belt is tight. Tighten the tensioner pulley nut.
the 5.3 is a v-8, not v-6. Anyways...locate the belt tensioner, put wrench on tensioner, remove tension and slip belt off. There should be a diagram of belt, pullies, and tensioner under the hood.
The belt on a Dodge Stratus 2. 5L V6 is changed by loosening the belt tensioner and slipping the belt off the pulley. It can then be taken off the engine accessories and a new belt installed.
