2022 Chevrolet Tahoe Serpentine Belt: Routing, Replacement, and Part Numbers

Quick Answer

For your 2022 Chevrolet Tahoe, the serpentine belt system is crucial for powering accessories. Here are the key details:

• Belt Length & Rib Count: The primary serpentine belt is typically a 6-rib belt, approximately 107.5 inches (2730mm) long.
• OEM Belt Part Number: GM 12693350
• Aftermarket Cross-References:
  • Gates K061075
  • Dayco 5061075
  • Continental Elite 4061075
• Auto-Tensioner Part Number: GM 12678693 (often crosses to Gates 38159, Dayco 89369, Continental Elite 49369)
• Idler Pulley Part Number: GM 12613583 (often crosses to Gates 36340, Dayco 89045, Continental Elite 41945)

Note: Part numbers are subject to change and may vary slightly based on specific engine options (e.g., 5.3L V8 L84, 6.2L V8 L87, or 3.0L Duramax I6 LM2). Always verify with your VIN.

Belt Routing

Always photograph your existing belt routing before removal to ensure correct reinstallation, as some variations can exist. For the 2022 Chevrolet Tahoe with the common V8 engines, the serpentine belt typically follows this path:

1. Crankshaft Pulley: The belt originates and receives power from the main crankshaft pulley, located at the bottom center of the engine.
2. A/C Compressor: From the crankshaft, the belt usually routes upwards to the air conditioning compressor pulley, often found on the lower passenger side of the engine.
3. Idler Pulley (lower): After the A/C compressor, the belt often passes over a lower idler pulley, which helps guide the belt.
4. Alternator: The belt then goes to the alternator pulley, usually located higher up on the passenger side of the engine.
5. Power Steering Pump: From the alternator, the belt typically wraps around the power steering pump pulley, often situated towards the top driver's side of the engine.
6. Water Pump: Next, the belt typically engages with the water pump pulley, which is generally located centrally on the front of the engine, above the crankshaft.
7. Tensioner Pulley: Finally, the belt routes to the automatic tensioner pulley, which maintains proper belt tension. The tensioner is usually found on the upper driver's side or central upper part of the engine.

The belt then returns to the crankshaft pulley, completing the circuit. Referencing your specific engine configuration and documenting the existing route is crucial.

How to Replace the Serpentine Belt

Replacing a serpentine belt on your 2022 Chevrolet Tahoe is a common maintenance task, but requires the right tools and careful execution.

1. Safety First: Ensure the engine is off and cool. Disconnect the negative terminal of your battery.
2. Document Routing: Take clear photos or draw a diagram of the current belt routing.
3. Locate Tensioner: Identify the automatic belt tensioner. It will have a square drive hole (typically 3/8
