2-1/16" CAN-Bus Water Temperature Gauge | 120-260F with Warning | Holley EFI

Holley EFI Water Temp Gauge reads coolant temperature directly from the Holley EFI ECU through the CAN network for a cleaner install with no external sender required when supported. Built for seamless integration with supported Holley EFI systems, it delivers real-time water temperature data while keeping wiring simple and the setup clean. A precision stepper motor keeps the pointer smooth, stable, and easy to read at a glance, while programmable high and low temperature warnings and a settable warning light provide a clear visual alert when coolant temp moves out of range. Daisy-chain capability makes it easy to add multiple gauges on the same CAN network. Built for long-term reliability, it’s made in the USA and backed for life.
