An accurate water temperature gauge is crucial for high-performance vehicles and daily drivers alike. Whether you prefer the reliability of mechanical gauges or the advanced features of electric gauges, Summit Racing has the right gauge for your vehicle—even your boat!

Mechanical water temperature gauges typically feature an easy-to-read analog display with a dial and pointer. They use a permanently attached sensing tube that threads into the engine’s cooling system. The tube is filled with gas or liquid, which expands or contracts as the coolant temperature changes, causing the gauge pointer to move. These gauges require no electricity to operate (unless they’re equipped with a backlight), and they can provide accurate readings even when the vehicle is turned off. Electric water temperature gauges use an electronic sending unit to measure coolant temperature and transmit the data electronically to the gauge. Available in both analog and digital configurations, electric gauges give you flexible display options. Analog versions maintain the traditional look, while digital gauges provide precise numerical readings. Plus, select electric water temperature gauges feature additional options like overheating warning lights.

Summit Racing has the best selection of mechanical and electric water temperature gauges, plus accessories like gauge mounting panels and pods, sending units, and wiring. Shop today and get everything you need shipped to your door.
