This fixed speed water pump pulley, crafted from steel and finished in black, is designed to deliver consistent rotational force to the water pump at a set speed. Its 166 mm outer diameter and 52.8 mm height are optimized for proper belt engagement and efficient power transmission. The 3 mm thickness adds durability and resistance to thermal expansion and mechanical stress. This pulley’s robust construction ensures long-term performance, even under demanding conditions. Its fixed speed nature provides stability in the cooling system, ensuring predictable water pump operation, which is critical for maintaining engine temperature. The precisely machined mounting surface facilitates secure attachment, preventing slippage and misalignment. Regular inspection and replacement of this pulley help sustain optimal cooling performance, supporting engine longevity.
