EC Fan

An important player of the engine cooling system

The fan plays an important, supportive role for effective operation of the vehicle’s engine cooling system.

The EC fan forces air through the exchangers, such as the radiator and/or intercooler.

The EC fan keeps the engine’s coolant from rising above operational temperature, thereby preventing the system from overheating. Its role is especially important at low engine revs and low speeds in slow-moving traffic.

Technical Details

Depending on the vehicle application, the EC fan can be engaged by means of a thermostatic switch or the vehicle’s ECM.

A malfunctioning EC fan will have a negative impact on the engine cooling performance, which will cause excessive thermal stress on the engine.

As an electrical device, the fan is often exposed to failure due to problems with the vehicle’s electrical system, such as overvoltage, poor fuse, non-performing alternator and thermostatic switch failure.
