Analysis of the replacement cycle of the electronic fan for Mitsubishi GALANT models from 1999 to 2003:

I. Design lifespan and general replacement recommendations for electronic fans

Theoretical lifespan range

According to the general design standards for automotive electronic fans, their service life is typically 5-10 years or 200,000-300,000 kilometers, depending on the usage conditions and maintenance.

Original electronic fan: The average lifespan is about 5 years under normal operating conditions. However, if it operates under high load for an extended period (such as frequent traffic jams or high temperature environments), the lifespan may be shortened to 3-4 years.

Differences in driving methods: The lifespan of mechanical fans is typically 5-7 years, while electronic fans can last for over 10 years.

Key factors affecting lifespan

Speed and wear: High-speed operation will accelerate the wear of bearings and motors.

Battery status: Old batteries may lead to a shortened operation time of the electronic fan, indirectly affecting its lifespan.

Environment and maintenance: Dusty environments require more frequent cleaning, and insufficient lubrication can easily lead to early bearing failure.

II. Suggestions for practical use and maintenance

Judgment of replacement timing

Performance degradation: such as reduced cooling efficiency, abnormal noise, or intermittent stalling.

Age consideration: It is recommended to replace the vehicle preventively if its age exceeds 15 years (e.g., model year 2003 to 2025).

Maintenance measures to extend lifespan

Regular cleaning: Remove the dust accumulated on the radiator fins and blades every 20,000 kilometers to prevent airflow obstruction.

Lubrication inspection: Check the lubrication status of the bearing every 50,000 kilometers, using high-temperature resistant lithium-based grease.

Circuit maintenance: Regularly check the oxidation of relay and temperature control switch contacts.
