2017 Chevy Traverse Serpentine Belt Diagram (2024)

FAQs

How do you find a serpentine belt routing diagram? ›

Vehicle manufacturers produce serpentine belt diagrams that are designed to aid with this task. Some vehicles have the serpentine belt diagram located on a decal somewhere in the engine compartment.

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.

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.

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. If there is less than a half an inch, the belt will need to be loosened, if there is more, it will need to be tightened.

This industry standard number, frequently denoted as the “PK” number, is printed next to the manufacturer's part number on almost every serpentine belt produced, and can be seen in the examples below. WHAT IS A “PK” NUMBER? A “PK” number is a worldwide standard metric belt measurement printed on most serpentine 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.

Check if the belt runs centrally on the pulleys. Any sideward movement or slippage can indicate misalignment. Straightedge or String Line: Place a straightedge or taut string along the faces of the pulleys to see if they line up perfectly. Any deviation from a straight line suggests angular or parallel misalignment.

To check the alignment of the belt, place a straight edge or laser alignment tool across the face of the pulleys, making sure it touches both pulleys. Then, move the straight edge or laser to the side of the belt and check for any gaps between the belt and the straight edge or laser.

Excessive Wear: A serpentine belt that is too tight can cause excessive wear on the belt and other components, leading to premature failure. The added tension can cause the rubber on the belt to wear down more quickly, which can cause the belt to crack or break.

Moreover, Gates provides the following recommendation for inspecting automatic belt tensioners: - With the engine off and cold rotate the tensioner arm through its entire range of motion. Any sticking or roughness indicates wear on the tensioner bearing surfaces and will require replacement of the tensioner.

How do you relieve tension on a serpentine belt? ›

The way to remove tension will be to pivot the tensioner using a tool (1) on the nut of the tensioner pulley, or (2) a special tool-lug outcropping from the tensioner or (3) in a square opening in the bracket of the tensioner pulley, cover or cap that protects the spring.

The tensioner pulley is responsible for keeping the belt tense while making sure it stays aligned the entire time you're driving. While the location of the tensioner pulley can vary depending on the vehicle, you can usually find it at the end of the tensioner, which is typically connected to the accessory drive belt.

There are two ways to align pulleys: Traditional and laser. Traditional alignment methods are quick but often inaccurate. With these methods, mechanical tools such as straightedges, tape measures, wire, string, feeler gauges, spirit levels and calibrated cones are used.
