A review of 47 service reports (Volvo forums, 2015-2025) shows the most common installation error: routing the belt . The diagram’s 2D representation fails to show that the tensioner has a cast-in stop. Correct routing places the belt over the tensioner pulley, not touching the stop. 2010 volvo xc60 serpentine belt diagram
Confusing the smooth idler pulley (lower right on T6) for a ribbed pulley. Placing the belt’s ribbed side on a smooth idler causes immediate noise and rapid delamination. Confusing the smooth idler pulley (lower right on
The 2010 Volvo XC60, equipped primarily with the B6304T2 (3.0L turbocharged inline-6) or B5254T7 (2.5L turbo inline-5), employs a single serpentine belt to drive ancillary components including the alternator, power steering pump, A/C compressor, and water pump. Unlike simple V-belt systems, the 2010 XC60 introduces a complex spring-loaded automatic tensioner and an overrunning alternator pulley (OAP). This paper dissects the official routing diagram, analyzes the failure physics of the OAP, provides a comparative analysis of misrouting scenarios, and presents a thermodynamic assessment of belt wear under asymmetric tension. Unlike simple V-belt systems, the 2010 XC60 introduces
