OEM Mitsubishi Fans and Kits

Cool Your Engine Properly With Quality Fans and Kits

Have you ever considered the lifespan of your cooling fans or when they might need replacement? Fans and kits move air through the radiator to cool engine coolant. Electric fans activate based on temperature sensors, while mechanical fans connect directly to the engine through a clutch. Proper airflow prevents engine overheating during idle and low-speed driving. Fan assemblies include the motor, blades, shroud, and mounting brackets. These components must work together to provide adequate cooling capacity for your engine's heat output.

How Cooling Fans Maintain Engine Temperature

Electric cooling fans mount behind or in front of the radiator and activate when coolant temperature reaches a preset threshold. The fan motor spins plastic or metal blades that pull air through the radiator fins. A shroud directs airflow and prevents recirculation. High-speed and low-speed settings adjust cooling capacity to temperature needs. Mechanical fans use a viscous clutch that engages when engine temperature rises. At highway speeds, ram air provides sufficient cooling and fans cycle off to reduce power consumption. Vehicles like the Mitsubishi Colt and Mitsubishi Shogun require reliable fan operation to prevent overheating.

Common Fan and Kit Component Failures

Cooling fans fail when motors burn out from continuous operation or electrical problems. Fan blades crack from age and vibration, reducing airflow and creating noise. Motor bearings seize from lack of lubrication. Temperature sensors malfunction, preventing proper fan activation. Relay failures interrupt power to fan motors. Shrouds crack and break from heat and physical damage. Mechanical fan clutches leak fluid and fail to engage properly. Aftermarket fans often use smaller motors and fewer blades than original equipment. The radiator condition directly affects fan cooling efficiency.

When Fan Replacement Becomes Necessary

Replace cooling fans when engine temperature rises abnormally during idle or slow driving. Loud grinding or clicking noises from the fan area indicate bearing failure. Visible blade damage requires immediate replacement. Most electric fans last 80,000 to 120,000 miles. Test fan operation by monitoring activation temperature and airflow strength. Genuine Mitsubishi fans and kits provide proper airflow volume and pressure compared to universal aftermarket fans that may not match cooling requirements.
