Fan Controller With Pipe Thread Probe

The DERALE Fan Controller with Pipe Thread Probe (Model 16739) is designed for engine builders, performance enthusiasts, and mechanics who require precise management of cooling systems. This controller is ideal for modified street engines, restomod builds, and high-output swaps, allowing for independent control of fan engagement to optimize cooling efficiency and underhood temperatures.

Featuring a pipe thread probe design, this controller integrates seamlessly into existing coolant passages or custom cooling systems without the need for block modifications. The probe directly senses coolant temperature and activates the fan at your set threshold, reducing unnecessary fan run-time that can impact horsepower and fuel economy. DERALE's engineering ensures smooth, adjustable control with reliable switching logic, making it suitable for high-amp electric fans or multi-fan setups.

This controller is perfect for street rods, engine swaps, turbo conversions, and late-model restorations, and it is compatible with aftermarket electric fans from DERALE and most major manufacturers. Installation requires basic wiring skills and access to a coolant passage for the probe integration, making it accessible for DIY enthusiasts and professionals alike.
