WATERWICH Oil Temperature Gauge Kit 2" (52mm) DC12V — 104–302°F Range, NPT 1/8" Sensor, Blue LED

WATERWICH Oil Temp Gauge Kit is a 2" (52mm) DC12V instrument with a NPT 1/8" probe that displays engine oil temperature from 104°F to 302°F with a blue LED readout and over-temperature warning.

This compact gauge kit includes the digital dial, wiring, and a threaded temperature sensor designed for straightforward installation into most oil galleries or adapter fittings. The bright blue LED face improves nighttime visibility while the internal alarm illuminates if oil temperature climbs above 248°F. It operates on standard 12V automotive systems and is intended specifically for measuring oil temperature (Fahrenheit model shown).

How easy is the WATERWICH oil temperature gauge to install?

Installation is designed to be user-friendly: the package supplies the temperature probe, wiring harness, and clear mounting instructions for a 2" dashboard hole. The sensor thread is NPT 1/8", a common size that fits many oil ports or adapter fittings, so most DIYers or professional installers can fit it without custom machining.

• Includes sensor with NPT 1/8" thread for direct mounting or adapter use
• 2" (52mm) gauge size fits standard dashboard cutouts
• Prewired harness simplifies connection to a DC12V system and warning lamp

What temperature range and accuracy does the meter provide?

The gauge reads between 104°F and 302°F, covering typical operating and high-heat conditions encountered in automotive and light-truck oil systems. The LED numeric display gives fast, easy-to-read values so you can monitor changes in operating temperature quickly; a warning lamp activates above 248°F to alert you of potentially damaging heat.

• Measurement span: 104°F to 302°F (Fahrenheit model)
• Visual numeric readout for instant temperature checks
• Warning lamp illuminates at temperatures over 248°F

Will this gauge work with my vehicle and electrical system?

The gauge is a universal DC12V device intended for use in cars, SUVs, trucks, and many light-duty vehicles. It measures oil temperature only and requires a 12V power supply; if your vehicle uses 24V or another system, a voltage converter or a different gauge model is needed. If you prefer Celsius, WATERWICH offers a separate Celsius version.

• Designed for 12V automotive electrical systems
• Compatible with cars, SUVs, vans, and light trucks when fitted correctly
• Fahrenheit display; Celsius models available separately

Who is this for?

This kit is intended for automotive owners, tuners, and mechanics who want a compact, clear oil-temperature readout and an early visual warning of excessive oil heat. It suits people who perform routine maintenance, upgrade instrument clusters, or monitor temperatures during towing, track days, or heavy-load driving. Because it uses a standard NPT 1/8" sensor and a 2" dashboard footprint, it’s well suited for both do-it-yourself installers and professional shops wanting a reliable, easily readable oil temperature gauge.
