Notes on Fitment:
• Commonly serves as the A/C accessory belt tensioner, maintaining tension on the serpentine belt. 
• Exact compatibility depends on engine size (e.g., 4.8L, 5.3L, 6.0L, 6.2L), drive type, and model year. 
Always verify with a VIN-based parts lookup or check the part number on your existing tensioner to ensure precision for your vehicle.
