120-240 Water Temp Gauge

The AutoMeter 120-240 Water Temperature Gauge (Sport-Comp model 3433) is a mechanical analog water temperature instrument designed for vehicles requiring precise engine coolant monitoring. This 2-5/8-inch diameter gauge delivers full-sweep needle response across a 120 to 240 degree Fahrenheit range, making it essential for tracking engine thermal conditions during high-performance driving, towing, or extended use where coolant temperature stability is critical to engine longevity.

This water temp gauge features a black face with clear dial markings and analog needle indication, providing immediate visual feedback without electronic dependency. The mechanical design eliminates electronic lag, delivering real-time temperature data as coolant conditions change. The full-sweep mechanism ensures the needle travels the complete gauge arc, maximizing readability across the entire 120–240°F operating window. This direct-reading format allows drivers to spot thermal anomalies—rising temps, sudden drops, or temperature spikes—at a glance without relying on dashboard warning lights or digital readouts.

The Sport-Comp water temperature gauge is commonly installed in performance vehicles, custom hot rods, marine applications, and heavy-duty trucks where OEM instrumentation may be insufficient or unavailable. Users value the AutoMeter water temp gauge for its straightforward installation, reliable mechanical response, and compatibility with custom dashboard setups. The 2-5/8-inch size allows flexible mounting in dash pods, custom panel clusters, or windshield suction-cup holders, making it equally at home in a restored classic or modern performance build.

AutoMeter gauges are engineered for accuracy and durability in demanding environments where temperature monitoring prevents engine damage from thermal stress. The mechanical needle response is faster than electronic sensors, critical during sudden load changes or towing scenarios where coolant temperature can shift rapidly.
