2-1/16in U/L Water Temp Gauge w/Peak & Warning

The 2-1/16in U/L Water Temp Gauge with Peak & Warning is an essential monitoring instrument for serious engine builders and performance enthusiasts who demand real-time thermal data. Whether you're running a naturally aspirated street engine, a turbocharged build, or a competition platform, precise water temperature monitoring prevents catastrophic overheating and allows you to optimize cooling system efficiency. This compact gauge fits seamlessly into custom dash installations and aftermarket gauge clusters, giving you the visibility needed to catch thermal issues before they damage your engine.

Built with Ultra-Lite construction, this 2-1/16-inch gauge delivers accurate temperature readings while minimizing weight—critical for track cars and weight-sensitive builds. The integrated peak memory function captures the highest temperature reached during operation, allowing you to review thermal behavior after driving sessions or dyno runs. The warning feature alerts you audibly or visually when coolant temperature exceeds your set threshold, providing an active safety net that responds faster than driver observation alone. The compact 4.9 x 4.5 x 5-inch profile and 0.73 lbs weight make installation straightforward in factory or custom mounting locations without requiring extensive modification.

This gauge benefits mechanics upgrading cooling systems on high-output engines, restoration specialists restoring classic vehicles with modern powerplants, and DIY builders who want professional-grade instrumentation without the premium price. The peak and warning functions are invaluable during engine tuning, suspension work, or extended highway driving where thermal stress testing is necessary. Installation requires a sender unit in the engine block or coolant passage; compatibility varies by engine platform, so verify sender location and thread size before purchase. For street cars, race builds, RVs, and marine applications, this gauge provides the thermal intelligence needed to keep your investment running strong.
