Is there a way to adjust the tension on the drive belt?

There are a few different ways to adjust the drive belt or V-belt tension in a vehicle. The most popular used nowadays is a serpentine belt that connects to and activates every pulley in the engine. These serpentine belts require no tension adjustment as they incorporate an automatic belt tensioner.

Do you need to adjust tension on a serpentine belt?

These serpentine belts require no tension adjustment as they incorporate an automatic belt tensioner. This type of tensioner has an internal pre-set spring and applies the correct amount of tension to the belt.

How do you remove a belt tensioner on a car?

Some older vehicles would allow you to loosen the bolts on the alternator, including the bracket-retaining bolt. This would allow the alternator to move back and forth along the slot inside the bracket. To remove the belt or lessen the tension, the alternator would cock in a position to relieve the tension.

What kind of belt tensioner do I Need?

The most popular used nowadays is a serpentine belt that connects to and activates every pulley in the engine. These serpentine belts require no tension adjustment as they incorporate an automatic belt tensioner. This type of tensioner has an internal pre-set spring and applies the correct amount of tension to the belt.

What noise does a bad tensioner pulley make?

Any noise that sounds like a squealing, whirling, or chirping might be a sign that the tensioner is weakening. The pulley bearings should be ruled out first because loose bearings can also cause such a noise.

How do you check a serpentine belt tensioner?

Use a ruler to check the belt’s tension. In many applications, the serpentine belt needs only to be reasonably tight. Because of this, a belt tension gauge is not necessary for most vehicles. Instead, use a ruler to measure the distance between the two furthest pulleys and find the midway point.

What is a belt tensioner?

Belt Tensioners. A belt tensioner is a spring-loaded idler wheel that ensures the serpentine belt stays routed on its pulleys at the proper tension. The tensioner is sealed with no lubrication point and has about the same service life as the belt itself.

What is belt tension?

Belt tension is measured by plucking the belt span while holding a sensor close by. Belt tension is adjusted until the belt span frequency, or measured tension level is within manufacturer’s recommendations. The final step is to operate the belt drive system for a few hours, allowing the belts to stretch and seat properly in the pulley grooves.
