[Tensioner] (Backside) | [Alternator] | [Water Pump] | [Crank] --- [A/C] --- [Idler] --- [P/S Pump] | | (Ribbed) (Backside) power steering pump
| Feature | 2010 XC60 T5 (2.5L) | 2010 XC60 T6 (3.0L) | | :--- | :--- | :--- | | Number of accessories | 5 | 6 (includes extra idler) | | Tensioner location | Lower left (near crank) | Upper right (near alternator) | | Belt length | 6PK 2230 mm | 6PK 2345 mm | | Common misrouting | Routing belt under idler instead of over | Confusing smooth idler with ribbed idler |
| Symptom | Diagram Area to Inspect | Likely Cause | | :--- | :--- | :--- | | Chirp on startup | Alternator wrap | Seized OAP | | Squeal at full lock | Power steering pump | Low fluid or belt slippage | | Constant rubbing noise | Smooth idler | Worn bearing or misrouting | | Cracks on belt back | Tensioner pulley | Glazed tensioner surface |
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.
