Water Temperture Kit

The AEM Electronics Water Temperature Kit (SKU AEM30-2012) is a precision electric temperature sending unit designed for engine monitoring systems and custom instrumentation applications. This kit serves mechanics, enthusiasts, and engine builders who require reliable coolant temperature data for tuning, diagnostics, and real-time engine management. The water temperature sending unit integrates seamlessly into existing cooling systems, providing accurate readings essential for preventing overheating and optimizing engine performance across a range of operating conditions.

This electric temperature sending unit features a 1/8 inch NPT male thread connection, making it compatible with standard cooling system ports found on most domestic and import engines. The kit includes both plug and pins, eliminating the need for separate electrical connectors and ensuring proper installation out of the box. AEM Electronics engineered this unit to deliver consistent, repeatable temperature signals to aftermarket gauges, engine control units, and data logging systems, with the compact dimensions (3.35 x 2.35 x 4.8 inches) and lightweight design (0.13 lbs) allowing flexible mounting in tight engine bay spaces without adding unnecessary weight or bulk.

Engine builders, tuners, and performance shops benefit most from this water temperature kit when upgrading cooling systems or installing custom gauges and ECU systems. The electric sending unit operates independently of mechanical gauges, offering superior accuracy and the ability to trigger warning lights or fan controls at precise temperature thresholds. Installation requires only basic mechanical skill—thread the unit into any 1/8 NPT port on the water jacket, thermostat housing, or coolant manifold, connect the included pins to your gauge or ECU input, and calibrate according to your instrument specifications. This kit is ideal for street cars, track vehicles, and engine test stands where data integrity and real-time temperature monitoring are critical to performance and engine longevity.
