High-Performance Radiator Fan Clutch

As an important part of the engine cooling system, the radiator fan clutch is the key to controlling the speed of your engine fan. It can effectively control the temperature, reduce the load of the engine, and improve fuel performance. However, such a key part often encounters problems such as impurities entering and poor lubrication, which will directly cause your radiator to shut down. Therefore, regular inspection and maintenance can extend its service life and avoid sudden failures. To prevent serious damage to your radiator, we provide high-quality radiator fan clutches designed to achieve reliable cooling in harsh environments and help your cooling system maintain optimal performance.

Common Types of Radiator Fan Clutches

Thermal Type: Uses a bi-metallic sensor that reacts to the temperature of the air passing through the radiator to engage the clutch. It is the most common application type and can usually provide refrigeration functions as needed.

Non-Thermal Type: Usually, it operates in meshing according to the rotational speed of the engine driving the pulley. It is a Simpler system where fan speed is directly tied to engine RPM.

Electronic Type: Controlled by the equipment's Engine Control Unit (ECU), which uses various sensors to engage the fan with precision.

Not all fan clutches are the same. They vary based on how they engage. Choosing the correct type is essential for restoring your cooling system's performance. We carry a wide range to fit various heavy equipment and truck models. If you want to explore more radiator parts, welcome to check out my parts catalogue for more information.

FAQs

What Does a Radiator Fan Clutch Do?

A radiator fan clutch regulates the cooling fan’s operation based on the engine’s temperature. It engages the fan when the engine heats up to increase airflow across the radiator and disengages it when cooling demand is low. This smart control reduces unnecessary load on the engine, improves fuel efficiency, and helps maintain consistent operating temperatures.

How Do I Know if My Radiator Fan Clutch is Bad?

Common signs of a failing fan clutch include inconsistent fan speeds, the fan running loudly or continuously, or failing to engage when the engine gets hot. If the fan spins freely with no resistance while the engine is off, it may indicate a worn-out clutch. Prolonged use of a faulty clutch can lead to overheating and reduce system performance.

Is it OK to Drive with a Bad Fan Clutch?

Continuing to operate machinery with a failing fan clutch is not recommended. Without proper cooling fan control, the engine is at higher risk of overheating, which can lead to major component damage and costly downtime.
