FAQs

Where is the serpentine belt diagram? ›

Some vehicles have the serpentine belt diagram located on a decal somewhere in the engine compartment. But if your car does not have a decal, you can easily look up the diagram in a repair manual or repair database. Another option is to take a photo of the old belt before removal.

If the belt is wobbling back and forth or the pulley is not spinning straight and wobbling, the pulley may be misaligned, which can cause the belt to squeal. Also, check if the belt is running in the center of the pulley and is not running off to the side.

Replacing the serpentine belt is as simple as threading it into position, cranking the tensioner and slipping the belt over the tensioner pulley, or nearest pulley up top. Belt tensioners are mostly spring tension. Once installed, the spring retains pressure to the belt.

A: Commonly a belt routing diagram sticker is on the underside of the hood or in the engine compartment. If there is no diagram, make a sketch of the belt and pulleys before removing the belt.

As an example, “8PK2515” is the PK number found on an OEM serpentine belt. The first digit indicates an eight-rib belt, followed by “P” to identify metric belt sizing, and a “K” showing that this belt conforms to the SAE standard for rib sizing (3.56 millimeters wide for automotive-type serpentine belts).

Misalignment – Misaligned pulleys will cause belt chirp noise problems and are caused by worn bearings. Cracked or Broken Pulley – Check for obvious physical damage. Free Spinning Pulley – Spin the pulley with your fingers.

The idler pulley is a component that supports the movement of your vehicle's drive belt. Common symptoms of a malfunctioning idler pulley include corrosion on the pulley's surface, chattering and squealing noises, and slow spinning. Recommended idler pulley brands include Replacement, Gates, and Dayco.

Squeaking, squealing or chirping sound from under the hood of the car. Check engine light or battery light is illuminated on your dashboard. A/C isn't working. Power steering isn't working.

Plus, replacement is relatively easy, and if you're wondering how long does serpentine belt service take, it's less than an hour for most vehicles.

Depending on the engine in your vehicle, the serpentine belt may be located at the front of the engine bay, or it may be along one side. There may be engine covers in the way, so be prepared to remove them if need be.

Since the serpentine belt helps provide power to cool the engine, a faulty belt can cause the car engine to overheat as the water pump will not turn. As soon as the engine begins to overheat, have it inspected by a mechanic as it can cause a breakdown and cause engine damage if left overheated.
