2-1/16 A/M Water Temp Gauge 100-260

The 2-1/16 A/M Water Temp Gauge 100-260 from AutoMeter is an electrical analog temperature instrument designed for serious engine builders and performance enthusiasts who demand accurate coolant monitoring. This full-sweep gauge provides real-time feedback on engine operating temperature, a critical parameter for tuning, diagnostics, and protecting your investment during high-performance driving or track sessions. Whether you're running a modified street engine, a turbocharged build, or a naturally aspirated classic, knowing your actual water temperature separates guesswork from data-driven maintenance.

This gauge measures coolant temperature across a 100–260 degree Fahrenheit range with electrical input from a compatible sender unit, delivering smooth full-sweep needle response for instant visibility into thermal conditions. The 2-1/16-inch diameter face fits standard gauge clusters and dash pods, while the brushed finish with black dial provides excellent readability in direct sunlight and at night. AutoMeter's American Muscle line combines precision analog movement with robust construction, ensuring reliability through heat cycles and vibration that would compromise lesser instruments—essential when monitoring turbo cooldown cycles or sustained high-load engine operation.

Mechanics and tuners favor this gauge for engine diagnostics, fuel-injection tuning validation, and early detection of cooling system faults before catastrophic failure occurs. Installation requires a matching water temperature sender unit and basic 12V electrical integration into your vehicle's harness or aftermarket ECU. This analog display is unaffected by electronic noise or sensor signal drift, making it ideal for older restoration projects, street rods, and modern performance builds where clear temperature trending matters more than digital noise.
