Speedmaster PCE184.1002 185/170 Degrees 3/8" NPT Thermostatic Fan Control Sending Unit Switch

The Speedmaster PCE184.1002 is a thermostatic fan control sending unit switch designed to automatically engage cooling fans based on engine or coolant temperature. This 3/8" NPT threaded unit operates at 185 and 170 degree settings, allowing the fan to activate when coolant reaches the upper threshold and deactivate at the lower threshold, providing efficient thermal management without manual intervention.

This sending unit is ideal for street rods, classic cars, custom hot rods, and other vehicles requiring aftermarket cooling system upgrades. The thermostatic design ensures your engine stays within optimal operating temperature by cycling the cooling fan on and off as needed. The 3/8" NPT connection fits standard cooling system ports, making it a direct replacement or upgrade option for many applications. Speedmaster's PCE184.1002 is engineered for reliable performance in high-heat environments where precise temperature control is critical.
