2-1/16in P/S II Water Temp. Gauge 100-260

The 2-1/16in P/S II Water Temp. Gauge 100-260 from Autometer is an essential instrument for serious automotive enthusiasts and mechanics who demand precise coolant temperature monitoring during performance driving, engine tuning, or daily operation. Water temperature management is critical to engine longevity and performance—too cold and your engine runs inefficiently; too hot and you risk catastrophic failure. This mechanical gauge delivers real-time feedback directly from your cooling system, eliminating guesswork and allowing you to make immediate adjustments to driving habits or engine parameters.

The P/S II series features Autometer's proven mechanical gauge design with a 100–260°F temperature range, covering everything from cold starts to high-heat racing conditions. The 2-1/16-inch diameter face mounts easily in standard gauge pods or dash openings, and the mechanical transducer eliminates electrical complications while delivering instant, reliable readings without lag or electronic failure points. Autometer's craftsmanship ensures smooth needle sweep, accurate calibration, and legible dial markings even under intense vibration or temperature fluctuation—critical attributes for modified vehicles, towing applications, or track use where engine stress is elevated.

This gauge benefits engine builders, turbo enthusiasts, and daily-driver modifiers who want non-negotiable visibility into cooling system health. Whether you've upgraded to a higher-flowing radiator, installed a performance thermostat, or are monitoring a freshly rebuilt engine, the 2-1/16in P/S II Water Temp. Gauge provides the feedback needed to optimize cooling strategy and prevent heat-related damage. Installation is straightforward for mechanically inclined owners—simply route the capillary tube from the gauge to the engine block water passage and secure the gauge in your chosen mounting location. Compatible with all fuel types and engine configurations that use traditional coolant systems.
