Good To Know

Q: Why does this switch list two OEM numbers? A: Honda used both 35250-HN4-670 and 35250-HN8-003 across the Foreman 500 range, and this switch covers both applications. Confirm the number on your original part before ordering.

Q: Will a bad switch cause my fan to run constantly? A: Yes, a switch stuck in the closed position keeps the fan running and can drain the battery. Replacing it restores normal fan cycling.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
