Fan Switch Kit

The DERALE Fan Switch Kit (model 16730) is a temperature-activated electric fan control module designed for automotive enthusiasts and mechanics who demand precise engine cooling management. This compact switching solution addresses a common challenge in modified and street-driven vehicles: maintaining optimal coolant temperatures without relying on mechanical fan clutches that waste horsepower. Whether you're running a custom radiator setup, fuel-injected engine conversion, or a rebuilt classic with modern cooling demands, this fan switch delivers the reliability and control needed to protect your investment while maximizing performance.

DERALE engineered this switch kit with adjustable temperature setpoints, allowing you to dial in engagement and disengagement thresholds that match your specific cooling system requirements. The solid-state construction eliminates mechanical wear and chattering associated with older thermal switches, ensuring consistent on-demand fan activation. Measuring just 2.75 x 1.4 x 4.25 inches and weighing only 0.17 lbs, the compact module integrates seamlessly into engine bays where space is at a premium—critical for turbocharged builds, supercharged applications, or vehicles with aftermarket radiators and tight shroud geometry.

The kit includes all necessary wiring harness connectors and mounting hardware for straightforward installation. Mechanics and hot rodders benefit most from this switch kit when upgrading cooling systems on carbureted conversions or modern engines. With its reliable performance and easy integration, the DERALE Fan Switch Kit is an essential component for anyone looking to enhance their vehicle's cooling efficiency.
