Vehicle Fitment

⚠️ Important: This idler pulley is specifically for supercharged petrol engines (3.0L V6 AJ126 and 5.0L V8 AJ133). Not for diesel, naturally aspirated, or 2.0L variants. Fitment varies by model year, production date, and VIN range – verify before ordering.

Signs of Failure

• Squealing or chirping noise – from the front of the engine, especially at start-up or under load

• Visible belt wear – cracking, glazing, or fraying on the accessory drive belt

• Belt off-track – misalignment of the serpentine belt

• Accessory malfunction – alternator / A/C / power steering issues

💡 The idler pulley is subject to wear over time from constant rotation. If the pulley fails, it can cause the drive belt to slip or break, potentially damaging other engine components .

Idler pulleys are VIN‑, engine‑, and model‑year‑specific. Variations in engine type (3.0L SCV6 vs. 5.0L SCV8), production date, and chassis configuration affect fitment. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.
