Womala Transmission Belt OE 31330244 Drive Belt for Volvo Transmission Parts

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.
