Speedmaster PCE184.1001 185/175 Degrees 3/8" NPT Thermostatic Fan Control Sending Unit

The Speedmaster PCE184.1001 is a thermostatic fan control sending unit designed to automatically manage electric cooling fan operation based on coolant temperature. This unit features a 185/175-degree setpoint, meaning the fan engages when coolant reaches 185°F and disengages at 175°F, providing precise temperature regulation for engine cooling systems. The 3/8" NPT thread connection allows direct installation into engine blocks or radiator tanks.

This thermostatic sending unit is essential for performance and street rod applications where proper engine cooling is critical. By automatically cycling the fan on and off at specified temperatures, it prevents overheating while reducing unnecessary fan runtime and parasitic drag on the engine. The unit's reliable two-stage operation ensures consistent coolant temperature management, making it an ideal upgrade for custom cooling systems, hot rods, and performance vehicles. Installation into standard 3/8" NPT ports makes retrofit and replacement straightforward for most engine configurations.
