2-1/16 Water Temp.Gauge

The AutoMeter 2-1/16 Water Temperature Gauge is a mechanical analog instrument designed for real-time engine coolant monitoring in vehicles where precise thermal management is critical. This full-sweep gauge reads from 120 to 240 degrees Fahrenheit, providing the wide range necessary to track coolant temperature across normal operating conditions and identify overheating before engine damage occurs. The 2-1/16-inch diameter fits standard gauge clusters and aftermarket dash installations where space is limited.

Mechanical operation means this gauge requires no electrical power supply—only a capillary tube connection to the engine block or coolant passage. The full-sweep movement delivers smooth, responsive needle action that reflects actual coolant temperature without digital lag. A black face with clear numerical markings ensures visibility in various lighting conditions, and the analog display is instantly readable at a glance. The Z-Series construction emphasizes durability and compatibility with standard automotive mounting solutions found in hot rod, classic car, and off-road restoration projects where vintage or minimalist gauge clusters are preferred.

This water temperature gauge suits builders and enthusiasts who value simplicity, reliability, and straightforward diagnostics. Mechanical gauges eliminate the complexity of electronic sensors and wiring harnesses, making them ideal for vehicles with custom engine swaps, modified cooling systems, or installations where electrical integration is minimal. The 120–240°F range captures the critical operating window: normal cruise at 180–210°F and warning conditions as coolant approaches thermal limits. AutoMeter's Z-Series has a reputation for accuracy and longevity in both street and competition applications.
