How to preset a tensioner pulley on a 93Ford 5.8

they are preset . if it is to tight replace it ,it has failed..the pulley itself will seize up next. use a ratchet to take off belt then remove tensioner.mudman1966

The idler pulley deflects out of the way using a special wrench, the pulley is held against the belt only by a preset spring tension mechanism. You put the wrench on the bolt or in the square drive hole and deflect the pulley away from the belt, it must be manually held there to put the new belt on and then released to tension the new belt.

The tensioner is preset, but the pulley can be replaced, if it is making noise or causing

the belt to slip. once belt is removed you should check it, and all pulleys if possible.

good luck!

Here's the procedure on how to release and replace the tension belt of your car.

Step 1

Open the hood on the Volvo S-60 and find the serpentine-belt routing diagram. The diagram should be attached to the top of the fan shroud that covers the radiator. If not, draw out the exact routing method of the serpentine belt around each pulley with a pen and a piece of paper.

Step 2 Locate the serpentine-belt tensioner that is in the very center of the engine. The tensioner will have a square bolt head in the center of the tensioner pulley.

Step 3 Slide the open end of the 5/8-wrench onto the square bolt head in the center of the belt-tensioner pulley. Turn the tensioner pulley counterclockwise and slide the serpentine belt off of the tensioner pulley.

Step 4 Remove the serpentine belt from the other pulleys and pull the belt out of the engine compartment.

Step 5 Slide the new serpentine belt into the engine compartment and around the crankshaft pulley.

Step 6 Route the new serpentine belt around each pulley. Turn the belt-tensioner pulley counterclockwise again and slide the serpentine belt around the tensioner pulley. Release the tensioner and it will tighten the belt around the pulleys. Look over the belt to ensure that it is inside of each pulley.

Step 7 Crank the S-60 and look over the serpentine belt with the motor running. Let the engine run for about one minute and shut the engine off. Close the hood.
