Could a broken radiator fan be causing my Suzuki Cultus engine to overheat?

The radiator fan in your Suzuki Cultus helps to regulate the engines temperature by pulling air through the radiator when the vehicle is idling o r moving slowly. If the fan fails due to a malfunctioning motor, relay, o r fuse, the engine wont get enough airflow to cool the coolant, leading to overheating. You might notice that the engine overheats when youre stuck in traffic o r during slow-speed driving. Its important to check the radiator fan and its components to ensure they are working properly.

Yes, a broken o r malfunctioning radiator fan can lead to engine overheating. The radiator fans job is to draw air through the radiator to cool the coolant, especially when the vehicle is idling o r driving at low speeds. If the fan motor is faulty, the fan will not spin, reducing airflow through the radiator and preventing heat dissipation. This leads to the engine temperature rising quickly, particularly in heavy traffic o r when idling for long periods. Common causes of fan failure include:

A damaged fan motor o r worn-out fan blades.

A blown fuse o r faulty relay that controls the fan.

A malfunctioning fan switch that fails to signal the fan to turn on when needed.

If you suspect the radiator fan is not working properly, have it checked. A faulty fan can be repaired o r replaced to restore normal engine cooling.
