Important

❗ This is the main auxiliary / serpentine belt tensioner, not a timing-chain tensioner
❗ M57N2 fitment is application-specific — confirmed catalogue coverage includes 306D3, 306D4 and 306D5, but always check OE number
❗ Inspect the auxiliary belt, idler pulleys and crankshaft harmonic balancer at the same time
