2-1/16 GS Water Temp Gauge - 100-260

The 2-1/16 GS Water Temp Gauge by AutoMeter is an electric analog temperature monitoring instrument designed for serious engine builders, performance mechanics, and enthusiasts who demand real-time coolant temperature data. This full-sweep gauge replaces guesswork with precision, enabling you to monitor your engine's thermal operating window—critical for tuning, diagnostics, and preventing heat-related damage during high-load driving, track days, or forced-induction applications. Whether you're building a street engine, turbo platform, or daily driver, accurate water temperature feedback is non-negotiable for engine longevity and performance optimization.

The gauge features a black face with a 2-1/16 inch diameter housing, making it compact enough for tight engine bays while remaining legible at a glance. Its electric analog design uses a stepper motor mechanism that delivers smooth, full-sweep needle response across a 100–260 degree Fahrenheit range, covering everything from cold starts to peak operating temperatures and thermal stress conditions. The analog movement is more responsive and reliable than digital displays for at-a-glance trending, and the black bezel and face provide excellent contrast for rapid visual confirmation during driving. This construction also eliminates the lag associated with mechanical gauges, delivering immediate signal translation from the coolant temperature sensor.

Mechanics and tuners install this gauge in custom dash clusters, pillar pods, or mounting brackets to replace OEM instruments or add redundant cooling system monitoring. It pairs with a standard automotive coolant temperature sensor (sold separately) and integrates into any 12-volt electrical system. The 4.75 x 4.5 x 5.15 inch footprint and 0.72 lb weight make installation straightforward in most vehicles, from classic restorations to modern performance builds. Ideal for users who want AfterMarket gauge accuracy without proprietary electronics, this AutoMeter instrument is trusted by fabricators and engine shops for its durability, repeatability, and straightforward wiring.
