Pro Comp 2-5/8in Silver Liq-Fill Water 140-280

The AutoMeter Pro Comp 2-5/8 inch Silver Liquid-Filled Water Temperature Gauge (model 4631) is a precision instrument designed for serious enthusiasts who demand accurate real-time engine coolant monitoring. Whether you're running a modified street engine, competition vehicle, or daily driver that generates higher thermal loads, this gauge delivers the reliability and clarity needed to protect your investment.

Liquid-filled gauges eliminate needle flutter and vibration that plague air-filled alternatives, ensuring you catch temperature anomalies before they become catastrophic failures. This 140–280°F range gauge features AutoMeter's proven mechanical design with a dampening fluid that stabilizes the needle response across varying engine vibration levels. The silver bezel and bright face provide excellent visibility in any lighting condition, while the 2-5/8 inch diameter allows integration into most dash pods, pillar mounts, or custom gauge clusters without sacrificing gauge function or cockpit aesthetics.

Mechanics and tuners routinely spec this gauge for engine builds, turbocharged conversions, and vintage restorations where OEM instrumentation falls short or is simply unavailable. Its compact footprint and universal 1/2-inch NPT sender thread accommodate virtually any engine platform, making it a versatile choice for automotive enthusiasts.
