2-5/8in S/C Water Temp. Gauge - Metric

The AutoMeter 2-5/8in Sport-Comp Water Temperature Gauge in metric (model 3431-M) is a mechanical analog instrument designed to provide accurate real-time engine coolant temperature monitoring across the 60–140 degree Celsius range. This full-sweep gauge delivers precise readings through a proven mechanical design, making it an essential addition to any engine bay where detailed temperature management is critical.

The 2-5/8 inch diameter housing with black face provides excellent visibility from the driver's position while maintaining a compact footprint suitable for custom instrument panels and aftermarket dashboard installations. The full-sweep needle movement offers intuitive, at-a-glance temperature status without requiring the driver to interpret a narrow gauge band. Mechanical operation eliminates dependency on electrical sensors and their associated wiring complexity, while the gauge's proven AutoMeter construction ensures reliable long-term performance in demanding automotive and marine environments where coolant temperature stability directly impacts engine longevity and performance.

This metric-calibrated gauge is ideal for engine builders, restoration specialists, marine operators, and performance enthusiasts who require precise Celsius temperature data. Sport-Comp series gauges are commonly integrated into custom street rods, classic restorations, offshore vessels, and track-focused vehicles where OEM dashboard space is limited or metric readouts are preferred. The mechanical design makes it particularly valuable in high-vibration or extreme-temperature environments where electronic sensors may falter.

AutoMeter's Sport-Comp line represents a balance between affordability and functional accuracy, positioning this gauge as a practical solution for builders and operators who need dependable temperature monitoring without premium instrument cluster pricing.
