WATERWICH Water Temperature Gauge 2" Digital Coolant Meter 104–302°F with Blue Backlight & Overheat Warning

The WATERWICH digital water temperature gauge kit is a 2" (52mm) automotive meter that shows coolant temperature from 104°F to 302°F with a blue backlight and an overheat warning lamp.

This compact, easy-to-install gauge package includes the electric gauge, temperature sensor with NPT 1/8" thread, and wiring harness for DC 10–15V systems (nominal 12V). Designed for cars, trucks, SUVs and many aftermarket dashboards, the meter gives a clear Fahrenheit readout and a visual alert if coolant climbs above 212°F, helping drivers monitor operating temperature at a glance both day and night.

How does the WATERWICH gauge display temperature at night?

The gauge uses a bright blue backlight so numbers and scale stay readable in low light and during nighttime driving. The color and layout reduce glare while keeping the readout visible from typical instrument cluster angles.

• Blue LED illumination for consistent visibility
• High-contrast digits and scale for quick readings
• Visible from multiple viewing angles without distracting glare

What temperature range and warning settings does it support?

This WATERWICH meter measures coolant temperature between 104°F and 302°F, offering a wide operating span for most gasoline and diesel engines. A built-in warning lamp activates above 212°F to alert you to potential overheating before you notice symptoms.

• Measurement range: 104°F–302°F (readout in Fahrenheit)
• Overheat warning lamp triggers above 212°F
• Digital electric sensing for fast, accurate updates

How easy is installation and what hardware is included?

The kit arrives ready to fit with the gauge, an electric temperature sensor with NPT 1/8" mounting thread, and the required wiring. It is a plug-and-wire style install for 12V systems, suited to direct replacement into a 2" dash hole or mounting pod.

• Complete kit: gauge, sensor, and wiring harness included
• Sensor thread: NPT 1/8" — common for coolant ports and adapters
• Designed for 2" (52mm) dashboard cutouts and universal mounts

Will this fit my vehicle and can it use Celsius?

The gauge is made for universal automotive use on DC 10–15V electrical systems (nominal 12V) and is intended specifically for engine coolant or water circuits. This model displays Fahrenheit; WATERWICH offers a Celsius version separately if you prefer metric units.

• Compatible with cars, trucks, SUVs and many aftermarket setups
• Power supply: DC 10–15V (designed for 12V systems)
• Only for liquid temperature measurement — not for humans or animals

Who this product is for: drivers, mechanics and vehicle modifiers who want a compact, visible, and accurate coolant temperature meter for routine monitoring or performance builds. It suits everyday car owners who want better temperature awareness, DIY installers fitting aftermarket dashboards, and shop technicians who need a reliable, straightforward gauge with quick visual overheat notification.
