Description
Keep coolant temperatures in check with the AutoMeter Cobalt Water Temperature Gauge, designed to help you monitor engine heat and identify potential cooling system issues before they affect performance or reliability. Whether you're driving daily, towing heavy loads, or building a performance vehicle, keeping an eye on coolant temperature helps you understand how your engine is operating under different conditions. Available in 2-1/16-inch and 2-5/8-inch sizes, these gauges offer multiple temperature ranges and mechanical or electric operation to match your setup and dashboard preferences.
The mechanical versions use a precision Bourdon tube movement and are available in 120–240°F and 140–280°F ranges. They include a 6-foot capillary tube, a 1/2-inch NPT adapter, and mounting hardware, operating without an electrical connection to measure temperature. The electric versions feature an air-core movement, an included temperature sender, and a 100–250°F range, allowing coolant temperature to be monitored without routing a capillary tube into the cab. All options feature Cobalt's distinctive black dial, bright bezel, and blue LED through-the-dial lighting for clear readings and a coordinated performance-inspired look. Choose the gauge size, temperature range, and operating style that best suit your engine and installation.
