Adjustable Elec. Fan Wiring Kit Probe

The Adjustable Electronic Fan Wiring Kit Probe by PERMA-COOL is a complete fan control solution designed for engine builders, hot rod enthusiasts, and performance vehicle owners who demand precision temperature management. This kit addresses a critical cooling challenge: maintaining optimal engine temperature without relying on mechanical fans that drain horsepower or waste fuel. By automating electric fan engagement based on actual coolant temperature, this wiring kit lets your engine breathe easier while improving efficiency across highway and street driving conditions.

The Adjustable Electronic Fan Wiring Kit Probe features a push-in temperature probe that activates within a 170–210 degree Fahrenheit range, giving you full control over when your electric fan engages. A dedicated 21-amp relay handles the electrical load reliably, protecting your vehicle's charging system while delivering clean, consistent power to high-draw cooling fans. The complete harness eliminates guesswork during installation—all connectors, wiring, and relay terminals are pre-assembled and color-coded, reducing installation time and minimizing the risk of miswiring that could damage sensitive engine electronics.

This kit works best for owners upgrading to aftermarket electric cooling fans, whether in custom hot rods, classic car restorations, or modified street vehicles where stock cooling systems fall short. The adjustable activation range is particularly valuable in high-ambient conditions or during sustained low-speed driving where engine heat builds gradually. Installation requires basic automotive electrical knowledge and fits most vehicles with standard 12-volt electrical systems; compatibility should be verified with your specific fan's amperage rating to ensure the 21-amp relay capacity matches your cooling fan's draw specifications.
