Buy Mitsubishi Galant Engine Cooling Fan Modules

The Engine Cooling Fan Module is a crucial component in a vehicle's cooling system. It regulates the operation of the electric cooling fans that draw air through the radiator to dissipate heat from the engine. This module, also known as the radiator fan control module or cooling fan control unit, ensures that the engine maintains an optimal operating temperature by activating the fans when necessary.

A malfunctioning cooling fan controller can lead to several noticeable issues. One of the most common symptoms is engine overheating, especially during idle or slow traffic conditions when airflow is minimal. Another sign is the cooling fans not engaging or running continuously, which can drain the battery or cause the engine to run cooler than intended. Unusual noises coming from the fan area or the activation of the Check Engine Light may also indicate problems with the electric cooling fan module.

Certain diagnostic trouble codes (DTCs) can point to issues with the cooling fan control unit. Codes such as P0480 and P0481 relate to malfunctioning cooling fan circuits. P0480 indicates a problem with the Cooling Fan 1 Control Circuit, while P0481 refers to the Cooling Fan 2 Control Circuit. These codes can be retrieved using an OBD-II scanner and are helpful in diagnosing faults within the radiator fan control module.

When replacing or servicing the engine cooling fan module, it's important to disconnect the vehicle's battery to prevent electrical shorts. Ensure all electrical connectors are clean and securely attached to avoid intermittent operation. It's advisable to inspect the cooling fan assembly for any physical damage or debris that might hinder performance. Following the manufacturer's guidelines during installation helps ensure the cooling fan controller operates correctly and prolongs the lifespan of the component.
