Digital Gauge Thermatic Fan & EWP Switch Kit

The Digital Gauge Thermatic Fan & EWP Switch Kit by DAVIES, CRAIG represents a precision engine cooling solution designed for serious automotive builders and mechanics running high-performance applications. This controller manages both electric water pump (EWP) operation and thermatic fan engagement with independent digital logic, eliminating the need for multiple aftermarket modules. If you're upgrading to a modern cooling setup on a classic car, race vehicle, or custom build, this kit delivers the intelligent thermal management required to keep engine temperatures stable across varying load conditions while reducing parasitic drag on your crankshaft.

Built with DAVIES, CRAIG's reputation for reliability, this switch kit features independent sensor inputs and relay outputs capable of managing both 12V cooling circuits simultaneously. The digital interface allows separate temperature thresholds for EWP activation and fan engagement, giving you granular control over cooling strategy—critical when tuning flow rates and minimizing unnecessary cooling load during lower-speed cruising. Compact dimensions (5.2 x 3.3 x 7.8 inches) and lightweight construction (1.4 lbs) make installation straightforward in engine bays with space constraints, while the modular design integrates cleanly with OEM or custom wiring harnesses.

This kit is ideal for engine swap projects, LS conversions, vintage restorations with modern cooling systems, and track-focused builds where precise thermal control directly impacts performance and reliability. Installation pairs easily with aftermarket radiators, aluminum water blocks, and high-flow EWP units common in contemporary hot rods and competition vehicles. Whether you're a professional engine builder, weekend fabricator, or mechanic managing multiple cooling circuits on a complex drivetrain, the Digital Gauge Thermatic Fan & EWP Switch Kit eliminates guesswork and delivers repeatable, dependable results.
