2-5/8 Ultra-Lite Water Temp 120-240 F.Mech 12FT

The 2-5/8 Ultra-Lite Water Temp 120-240 F.Mech 12FT by AutoMeter is the go-to mechanical water temperature gauge for serious engine builders and performance enthusiasts who demand accurate, real-time coolant monitoring without the complexity of electronic systems. Whether you're tuning a street rod, monitoring a boosted engine, or simply upgrading from an OEM cluster, this gauge delivers reliable temperature feedback in a compact, lightweight package that integrates seamlessly into custom dashboard builds or aftermarket gauge pods.

Built with AutoMeter's proven mechanical movement, the 2-5/8 Ultra-Lite gauge uses a sealed capillary tube system that responds directly to engine coolant temperature without lag or electronic interference—a critical advantage during dyno pulls or high-heat engine work. The 120–240°F range covers everything from cold-start diagnostics to sustained boost scenarios, while the ultra-lite construction minimizes unsprung weight in the cabin. The 12-foot capillary tube provides installation flexibility, allowing the sensor to mount deep in the engine bay or radiator hose while the gauge itself sits in your cockpit or pillar pod, all without voltage drop or signal loss.

Mechanics and tuners favor this gauge for engines running aggressive timing, nitrous, or turbocharged setups where water jacket temperature control is non-negotiable. The 2-5/8 inch face fits most universal gauge holders, 3-inch pod mounts, and custom fabricated panels, making it ideal for restomod projects, track cars, and race-prepped vehicles. Installation requires only coolant line access and a secure mounting surface—no wiring harnesses, no calibration, no potential electrical gremlins. AutoMeter's mechanical reliability ensures you'll get consistent, accurate readings for years of hard driving.
