Transmission Belt (Drive Belt, OE: 31330244) for Volvo
The Transmission Belt (also referred to as Drive Belt, OE Number: 31330244) is a critical powertrain and auxiliary system component engineered exclusively for a wide range of Volvo models. It serves a dual role: transferring rotational power from the engine’s crankshaft to the transmission (ensuring vehicle movement) and driving essential auxiliary systems (e.g., water pump, alternator, air conditioning compressor) depending on the vehicle’s configuration.
Constructed from a high-performance rubber compound reinforced with high-tensile polyester or aramid cords, this OE-grade belt balances exceptional flexibility, pressure resistance, and thermal stability. Unlike generic aftermarket belts, it adheres to Volvo’s strict engineering standards—its length, width, rib profile (for serpentine variants) or tooth pattern (for timing/cogged variants), and tension tolerance are precision-calibrated to match the original engine’s pulley system. This eliminates slippage, uneven wear, or power loss, ensuring seamless integration with Volvo’s powertrain and auxiliary components.
Core Functions
Dual-Purpose Power Transfer:
Transmission Drive: Delivers rotational power from the crankshaft to the transmission (manual or automatic), enabling the vehicle to accelerate, decelerate, and maintain speed by translating engine power into wheel movement.
Auxiliary System Drive: For serpentine belt configurations, it powers critical auxiliary components—such as the alternator (charges the battery), water pump (circulates engine coolant), and A/C compressor (provides cabin cooling)—ensuring no interruption to vehicle functionality.
Tension Stability: The reinforced cord structure maintains consistent tension under load (e.g., hard acceleration, towing, or A/C activation), preventing slippage. Slippage not only reduces power delivery to the transmission but also generates friction that overheats the belt and damages pulley surfaces.
Durability Under Extreme Conditions: Resists degradation from engine oil, coolant, road debris, and extreme temperatures (-30°C to 120°C). Its heat-resistant rubber compound prevents hardening, cracking, or melting in high-temperature engine bays, while the reinforced cords avoid stretching even under maximum engine load.
Precision Alignment & Low Noise: The smooth rib/tooth profile and OE-matched dimensions ensure perfect alignment with Volvo’s pulleys, minimizing operational noise (e.g., squealing or chirping) and reducing pulley wear—common issues with ill-fitting aftermarket belts.
Compatible Vehicles
This Transmission Belt (OE: 31330244) is widely compatible with Volvo’s sedan, wagon, hatchback, and crossover models. Below is a consolidated list of variants and applicable years:
Model
Applicable Years
Volvo S40 (04-)
2011–2012
Volvo V40 (13-)
2013–2015
Volvo V40 Cross Country
2013–2015
Volvo V50

2012–2015
Volvo V60 / V60 (-18)
2011–2015
Volvo V70 (08-)
2012–2015
Notes: “(04-)” / “(07-)” / “(08-)” / “(13-)” denote models launched from the specified year onward; “(-18)” indicates variants produced up to 2018. For 100% fitment accuracy, confirm compatibility with your vehicle’s VIN (Vehicle Identification Number) or Volvo’s official service manual—this accounts for engine-specific configurations (e.g., 4-cylinder vs. 6-cylinder, turbocharged vs. non-turbocharged) and regional powertrain variations.
Frequently Asked Questions
