What does a loose alternator belt sound like?

A loose drive belt will often be noisy, squeaking a bit, or emitting a high-pitched squeal. The most obvious sign of a loose drive belt, though, is in its appearance and tension. They are the v-belt and serpentine belt. Belts are used to rotate components on the engine assembly, such as a coolant pump (water pump).

How much tension should a alternator belt have?

You want to be able to press down on the belt at a mid point between two pulleys and only be able to move it downward about 1/8 to 1/4 inch. When you have the alternator in the right position, have an assistant tighten the top bolt and nut to lock the alternator in.

Why is my alternator belt loose?

There is one or multiple pulleys connected to the alternator and the belt keeps them wrapped around. This belt wears out over time, making it getting loose to the point of coming out of the pulley.

Does alternator belt squeal?

As the serpentine belt’s primary aim is to transmit power from your engine pulley to other belt-driven components, if your belt goes bad or you replaced a low-quality belt that does not have enough strength to carry all the pulleys along, it produces a whirring or squealing noise.

Is it bad to drive with a squeaky belt?

That’s why it’s recommended that the serpentine belt is replaced early when the squealing symptoms are first noticed. Although it may be safe to drive with the squealing for a few days or weeks, the belt will eventually need to be replaced, and for safety, the earlier it’s repaired, the better.

This silicone lubricant spray is great for use on cables, pulleys, guide rails, valves, linkages, hinges, locks and more. Effective in-use temperatures ranging from -100° F to 500° F.

Should you lubricate a serpentine belt?

Today, you should never put belt dressing on an EPDM-made serpentine belt. Belt dressing, and other oils and solvents, may quieten the belt noise when first applied, but these oils will actually cause the belt’s rib surface to become more aggressive once they dry out, leading to even more belt noise issues.
