Important Info: Always refer to the specific service manual for your vehicle to ensure proper routing, as variations may exist based on the engine configuration (single or dual alternator).

Replacing the Serpentine Belt

When replacing the serpentine belt, follow these steps:

  • Gather Tools: You will need a 1/2" breaker bar or a serpentine belt tool.
  • Release Tension: Use the breaker bar to relieve tension on the tensioner pulley.
  • Remove Old Belt: Carefully slide the old belt off all pulleys.
  • Install New Belt: Route the new belt according to the diagram, ensuring it sits correctly on each pulley.
  • Check Alignment: After installation, double-check that the belt is aligned properly and seated in all grooves.

Important Note: It is advisable to replace any worn components such as the tensioner and idler pulleys during this process to prevent future issues.
