Overview of the Chevy Traverse Belt System
What Is a Serpentine Belt?
The serpentine belt, also known as a drive belt, is a single continuous belt that powers multiple engine accessories. Unlike older systems that used separate belts for each component, modern vehicles like the Chevy Traverse utilize a serpentine belt for efficiency and simplicity.
Key Components Driven by the Belt
The belt typically drives:
- Alternator
- Power steering pump
- Water pump (sometimes driven by the timing chain/belt)
- Air conditioning (A/C) compressor
- Crankshaft pulley (the primary pulley from which the belt routes)
- Idler pulleys and tensioners to guide and maintain proper tension

Understanding the Chevy Traverse Belt Diagram
Visual Elements of the Belt Diagram
A typical Chevy Traverse belt diagram features:
- The crankshaft pulley, often at the bottom or front center
- The routing path of the serpentine belt, shown as a continuous line
- Pulleys representing each driven accessory
- Tensioner pulley, which maintains belt tension
- Idler pulleys, which guide the belt’s path
- Labels or numbered points indicating components
How to Interpret the Diagram
- Identify the crankshaft pulley as the starting point
- Follow the belt path visually, noting how it wraps around each pulley
- Recognize the tensioner and idler pulleys, which help maintain proper tension and routing
- Use the diagram as a reference during inspection or replacement

Step-by-Step Guide to Reading and Using the Belt Diagram
Steps for Proper Belt Inspection
1. Locate the belt diagram: Find the diagram sticker or refer to the manual.
2. Visual inspection: Check for cracks, fraying, or glazing on the belt surface.
3. Check belt tension: Press down on the belt midway between pulleys; it should have about 1/2 inch of give.
4. Ensure pulley alignment: All pulleys should spin freely and stay aligned without wobbling.
Steps for Replacing the Serpentine Belt
1. Gather necessary tools and parts:
- New serpentine belt
- Socket wrench set
- Belt tensioner tool or breaker bar
2. Locate the belt tensioner: Usually a pulley mounted on a spring-loaded arm.
3. Relieve tension:
- Use a tensioner tool or socket wrench to rotate the tensioner pulley, releasing belt tension.
4. Remove the old belt: Carefully slide it off the pulleys.
5. Compare the new belt: Ensure the new belt matches the pulley sizes and length.
6. Route the new belt:
- Follow the diagram precisely.
- Make sure the belt sits correctly in all pulley grooves.
7. Reapply tension:
- Release the tensioner slowly, allowing it to apply tension to the new belt.
8. Double-check the routing:
- Confirm the belt sits properly on all pulleys.
9. Start the engine:
- Observe belt operation for proper alignment.
- Listen for unusual noises.
