Womala Transmission Belt OE 31316870 for Volvo Auto Transmission Parts

Core Functions

• Power Transfer: Transmits rotational power from the engine’s crankshaft to the transmission (or auxiliary components), enabling the vehicle to accelerate and maintain speed. For serpentine belt variants, it also drives essential systems like the water pump, alternator, or air conditioning compressor—ensuring no interruption to vehicle functionality.
• Tension Stability: The reinforced cord structure maintains consistent tension under load (e.g., hard acceleration, towing), preventing slippage. Slippage not only reduces power delivery but also generates friction that can overheat the belt and damage pulley surfaces.
• Durability Under Stress: Resists degradation from engine oil, coolant, and road debris—common contaminants that break down generic belts. Its heat-resistant rubber compound also prevents hardening or cracking in high-temperature engine bays, extending service life.
• Precision Fit: Matches the exact dimensions of Volvo’s pulley system, ensuring proper alignment. Misaligned belts cause uneven wear, noise (e.g., squealing), or premature failure—this OE part eliminates alignment issues with factory-matched specifications.

 Compatible Vehicles
