142-1931 Cooling Fan Blade — Cat Engine 3406C

This cooling fan blade is designed to move a high volume of air through the engine's radiator, maintaining optimal operating temperatures for the CAT 3406C engine. It is constructed from durable materials to withstand the rigors of constant rotation and environmental exposure, ensuring reliable performance unlike a bent or damaged blade that can cause imbalance and reduced airflow. Operators may notice higher engine temperatures or the coolant temperature warning light illuminating if the fan blade is compromised.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most immediate symptom of a damaged cooling fan blade is an increase in engine operating temperature, potentially leading to the coolant temperature warning light. If ignored, the reduced airflow can cause the engine to overheat under load, leading to reduced performance and potential damage to engine components. Prolonged overheating can cause severe internal engine damage.

Installation Tip

Ensure the fan mounting surface on the water pump or fan hub is clean and free of debris before installing the new blade. Do not overtighten the mounting bolts, as this can strip the threads or warp the fan hub.

Service Note

Inspect the fan belt, tensioner, and radiator for any signs of damage or blockage when replacing the cooling fan blade.
