Keep an eye on your engine's cooling system with this 52mm auto water temperature meter. It gives you a clear digital readout so you can spot overheating before it becomes a problem. The kit includes the gauge, a water temperature sensor, and a 1/8NPT adapter for a straightforward installation.

This universal LCD thermometer works on both 12V and 24V electrical systems, making it a practical choice for cars, trucks, and motorcycles. The digital display is easy to read at a glance, and the compact 52mm size fits into standard gauge pods or dash openings without taking up too much space.
