Specs At A Glance

Good To Know

Q: How do I know the switch has failed? A: A switch that never closes leaves the fan off and coolant temps climbing, while one that sticks closed runs the fan from startup.

Q: Does this come with new hardware? A: It is supplied as the switch alone, and reusing the original mounting fitting is typical during installation.

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