If you notice that there is resistance, roughness, or noise every time you turn the pulley, then there’s a chance that the problem is in the pulley bearings. You might think of replacing only the pulley bearings in this case. Mechanics will tell you to replace the entire belt tensioner system.
What does a loose belt tensioner sound like?
If the drive belt noise resembles a squeal or a squeak, it is possible that the belt tensioner is loose. This is especially the case when starting the engine first thing in the morning. Since the tensioner is not able to maintain the correct tension on the belts, it produces a squealing or squeaking sound.
What does the pulley on a belt tensioner do?
The pulley is what allows the movement of the drive belt. The spring keeps the drive belt in its correct tension. The tensioner arm is a mechanism that allows for the adjustment or the removal of the drive belt. It delivers enough slack on the drive belt for easier adjustments. The base is what holds all the different parts together.
Can a bad belt pulley cause a car to break?

Most modern vehicles use a serpentine belt to run the engine accessories such as the power steering, air conditioning and alternator. The belt routes around the pulleys in a serpent-like manner, hence the name. A belt tensioner that consists of a bolt plate that mounts on the engine, a spring-loaded arm and a pulley applies tension to the belt.
How do you replace a serpentine belt pulley?
Using the breaker bar or serpentine belt tool, move the tensioner arm against the spring as far as it will move, to its stop. The tensioner arm should move smoothly throughout its range of travel, with firm spring pressure and without binding. Most tensioner pulleys can be replaced independently of the tensioner itself.
How can I tell if my serpentine belt is out of alignment?
Belt tension on the pulley pulls the shaft off center, which puts that pulley out of alignment with the other pulleys. Pulley alignment can be checked with a straightedge. Place the straightedge across two pulley faces. The straightedge should lie flat across them. If it doesn’t, one of the pulleys is misaligned.
