Good To Know

Q: How can I tell if this fan switch is the problem? A: If the cooling fan never engages when the engine warms up, or runs constantly from a cold start, the switch is the likely cause. A continuity check at the rated temperature confirms the diagnosis.

Q: Is any rewiring required to install it? A: No, it threads into the factory location and connects to the stock harness. Verify your model year and connector type before ordering to ensure a proper match.

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