Land Rover Part Number: STC4168 - Fan Belt Tensioner
STC4168 is a fan belt tensioner fitted to the ancillary drive belt system on Range Rover P38 models with the 2.5-litre BMW M51 diesel engine. The unit uses a spring-loaded tensioning mechanism and a rotating pulley to keep the accessory drive belt at the correct operating tension, preventing belt slip and limiting pulley wear while maintaining consistent accessory drive speeds. Common signs that the tensioner requires replacement include belt noise, visible belt glazing or fraying, pulley play, and intermittent charging or cooling faults caused by belt slippage. When replacing the belt, inspect pulley bearing movement and spring travel and replace the tensioner where wear or damage is present. Check the compatibility information below against your V.I.N. before ordering.
