FAQs

How do you find a serpentine belt routing diagram? ›

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. This will help you re-route the new belt correctly.

Are Serpentine Belts Directional? Because nearly all serpentine belts are symmetrical, a new belt's direction of rotation usually doesn't matter. What does matter, though, is that the new belt is routed correctly around the pulleys. It's also important that the grooved side of the belt faces toward the pulley grooves.

Turn off the engine and remove the serpentine belt. Shake and spin each pulley to check if there is excessive play or noise. Any play or back-and-forth movement indicates a bad pulley bearing. This leads to misalignment, belt squeaks, and the pulley should be replaced.

Use a ruler to check the belt's tension.

Instead, use a ruler to measure the distance between the two furthest pulleys and find the midway point. Pinch that point between your index finger and thumb and move it back and forth. The belt should have about a half an inch of play when at the appropriate tightness.

EXAMPLE: 6PK1003 » 6 - This indicates the number of ribs on the belt; therefore, this is a 6-rib belt. » PK – The “P” indicates a metric designation, and the “K” indicates the belt is automotive per SAE J1459. » 1003 - This is the effective length of the belt expressed in millimeters.

Most vehicles nowadays usually have a belt routing sticker located somewhere in the engine compartment, making it even easier.

Misalignment pulleys or tensioner: If the belt is not properly aligned on the pulleys, it can wear unevenly or slip off entirely, leading to its premature failure. This situation usually happens if some of the components have been previously removed, replaced, and not returned in to place properly.

WAYS TO WEAR A BELT

Men will typically wear a belt counterclockwise, from left to right, with the end of the belt going through the buckle and ending on the left side of the zipper. However, a left-handed man might end up wearing their belt clockwise, from right to left, due to their dominant hand.

It's a good idea for customers to replace both the water pump and the timing belt simultaneously so that both parts are brand new and will wear at the same time.

Normally that would be caused bey either a bad idler or tensioner pulley allowing the belt to twist and try walking off the pulleys .

What are the two types of belt misalignment? ›

A chirping sound could stem from misalignment of a pulley or drive belt, as well as a host of other issues.

When a v-belt is too loose: When a v-belt sits loose on a pulley, the belt can slip while in motion and cause extra friction. The additional friction can result in a buildup of heat on the belt and the pulley. The excess heat can cause premature damage to your belts.

If the belt is already out of place, locate the driver's manual or the under-the-hood placard, where you'll find a sketch of the routing.

How To Identify a V-Belt Pulley. The easiest way to identify a V-belt pulley is by finding the part number or identification components on the pulley itself. Different brands, as well as different pulley types, have various ways they may display these numbers.
