How do I know if my tensioner pulley bearing is bad?

If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started. It is also possible for the tensioner pulley or bearing to wear out, in which case the vehicle will produce a grinding noise from the pulley.

What does a bad drive pulley sound like?

Squealing. When the engine is idling, a bad pulley may make a squealing sound. This is due to the bearings in the pulley going bad. The bearings may also make various other sounds such as clattering or even a rumbling sound, making the vehicle sound as if there was much more wrong than a bad pulley.

Is a tensioner pulley the same as an idler pulley?

The primary distinction between tensioners and idler pulleys is the presence of an adjustable bolt. Tensioners are positioned on the bolt through mounting. Idler pulleys are not mounted to an adjustable bolt. ... However, if bearings fail, tensioner and idler pulleys both require replacement.

How do I know if I need a new idler pulley?

For auditory cues, squealing noise from the engine belt can be a tell-tale sign. As the pulley wears, the engine belt may squeal as it rubs against the surface of the pulley. The issue will worsen with time. Generally, idler pulleys will eventually require a replacement.

What causes pulley misalignment?

While all of the pulleys may be running true, one or more of them could be sitting too far forward or back on its shaft. A common source of parallel misalignment is improper installation depth of press-fit pulleys, like those found on power steering pumps.

How much does it cost to replace a pulley bearing?

Idler Pulley Replacement Cost

The cost to replace the idler pulley of your driver belt will usually be somewhere between $80 and $200. The cost for the new part should only be anywhere from $40 to $90, while the cost of the labor will be anywhere from $40 to $110.

What happens when a pulley goes bad?

A damaged pulley can cause the drive or serpentine belt to dislodge. If that happens, all components that derive power from that belt will stop functioning. On most vehicles, these parts include the alternator, water pump, power steering, air conditioning system, and different exhaust components.

What does a bad engine bearing sound like?

Most people describe a bad wheel bearing as making a growling or rumbling noise (the sound is often mistaken for worn tires). Also, in some cases, a bad bearing may make a high-pitched grinding or squealing sound. In either case, the frequency of the sound will correspond to the rotation of the tires.

Does the tensioner pulley spin?

Checking the Tensioner

Spin the pulley to see if it spins freely. If you hear grinding or the pulley doesn't spin freely, replace the tensioner. When you replace the belt, it should take a lot of muscle power to move the tensioner. If you can move it easily, the spring tension is most likely not tight enough.
