1/2 inch to 5/8 the bolt is in the middle of some front wheel cars you have to jack up and unbolt engine mount and some you can use a 3/8 or 1/2 inch ratchet feel around with hand if it feels square its a ratchet round a rench
I have found using a socket with a racket wrench to be the easiest way to do it. When the tension is released the belt can be slipped off the tension pulley. The belt can be replaced the same way. Good luck.
To release the 1990 Cavalier serpentine tension, use a socket and a ratchet. Put the socket on the bolt heat in the middle of the pulley wheel, and pull to one side, and the belt will be loosened to be able to be removed.
it is either a 15 mm or 18 mm socket or wrench and just swing it, it will only turn one way and it will release the tension on the belt
you have to put a socket wrench into the hole on the tensioner and pull up on it to release the tension from the belt.
First you need a breaker bar and 19mm socket to fit the "tension bolt". Turn tension bolt clockwise to release tension in order to remove the serpentine belt.
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
There is a part called a belt tensioner that is spring loaded. IT has a pulley that is muonted to an arm. If you use a socket drive or socket depending on the particulars of it, you can move it enough to release the tension on it. Keep in mind it is spring loaded.
Put the proper size wrench or socket on the pulley of the tensioner.Pull the wrench counter clockwise to release the tension on the belt.
You don't. The serpentine belt tension is automatically maintained by the tensioner pulley, which is an idler pulley located on the passenger side of the system and looks like it doesn't drive anything. If the belt tension is incorrect, the tensioner pulley must be replaced. If the question meant 'how to release tension from the belt' (for removal, etc.), this is done by applying the correct size socket wrench to the tensioner pulley's center nut and rocking the pulley away from the belt.
Most likely there is a spring loaded device called a belt tensioner. There is a pulley on it with a bolt or square inset in it. sometime a socket or 3/8" drive extention can be used to move the pulley and release the tension on the belt.
19 mm 6-point socket, standard length not deep socket. goes on upper "nut" of idler tension arm. With 1/2" drive, pull towards front to relieve tension; remove belt from idler. Release tension. Complete removing old serpentine belt. Install new belt in same path, same side 'grooved'. Pull on idler arm (19 mm socket) to allow new belt onto idler arm. Check that belt is lined up with all grooves. Release tension; remove tools; done. from Queen Creek AZ.
this belt drive has a belt tensioner, you need to release the tensioner and then you can remove the belt. 2 differant styles of tensioners, one will have a 'inverted torx' fitting right on the front of the pulley, and the other one will have a 17mm socket fitting right below and to the left side of the pulley, just put your ratchet and socket on it and release the tension by turning counter clockwise and holding while you remove the belt.
