The Fan Pulley is a vital component of engine cooling system. It is designed to mount the engine fan and transfer power from the drive belt to the fan blades. The pulley itself is typically made of durable materials such as steel or aluminum, and features a grooved design to ensure proper engagement with the drive belt. This allows it to spin at high speeds, effectively circulating air through the radiator and preventing overheating. Over time, wear and tear can cause damage or misalignment of the pulley, leading to decreased performance or even complete failure of the cooling system. As such, regular inspection and maintenance are crucial for ensuring optimal engine function and preventing costly repairs.
