Digital Gauge Thermatic Fan & EWP Switch Kit

The Digital Gauge Thermatic Fan & EWP Switch Kit by DAVIES, CRAIG is engineered for engine builders and performance enthusiasts who demand precise thermal management on high-output or modified vehicles. This intelligent control module bridges the gap between traditional mechanical fan clutches and modern electric water pump (EWP) systems, allowing you to monitor and regulate coolant temperature with digital accuracy. Whether you're tuning a street car, prepping for track duty, or maximizing cooling efficiency in a custom engine bay, this kit eliminates guesswork and delivers repeatable thermal consistency that mechanical systems simply cannot match.

The Digital Gauge Thermatic Fan & EWP Switch Kit operates via programmable temperature thresholds, cutting on and off your fan or EWP at user-defined setpoints rather than relying on wax-stat or belt-driven engagement. The digital gauge provides real-time coolant temperature readout—critical feedback that lets you dial in your tune, validate radiator capacity, and catch thermal issues before they cause damage. The compact switching module measures 5.2 x 3.3 x 7.8 inches and weighs just 1.4 lbs, making it easy to integrate into tight engine compartments or custom ducting setups. Solid-state relay technology ensures clean electrical switching with minimal parasitic load, maximizing alternator efficiency and reducing drain during startup or idle conditions.

Drag racers, road racers, and street performance builders benefit most from this kit, particularly those running LS conversions, big-displacement naturally aspirated engines, or turbo applications where cooling consistency directly impacts horsepower and reliability. Retrofit installations work cleanly on vehicles already equipped with electric fans or EWP setups; the gauge mounts easily on the dash or A-pillar for constant visibility. Compatibility extends across most 12-volt automotive systems, and the thermostat-independent operation makes it ideal for custom builds where factory cooling control is unavailable or inadequate. Pair this with a quality radiator upgrade or electric fan shroud for maximum cooling margin on your next project.
