WATERWICH Oil Temperature Gauge Kit 2" (52mm) 104–302°F DC12V with Blue LED & Warning Light

The WATERWICH 2-inch oil temperature gauge kit displays oil temps from 104°F to 302°F with a blue LED readout, a warning lamp above 248°F, and a plug-and-play 12V sensor for automotive use.

This compact gauge kit gives drivers a clear, dedicated readout of oil temperature so you can monitor operating conditions more closely than with engine coolant readings alone. Built for dashboard mounting, the kit includes the 52mm (2") instrument, a temperature sender with NPT 1/8" thread, wiring and a high-contrast blue backlight that stays visible at night. The unit runs on DC 12V and is designed as a universal fit for cars, trucks, SUVs and other vehicles that use a dedicated oil temperature sender.

How easy is it to install the WATERWICH oil temperature gauge?

Installation is straightforward for anyone comfortable with basic auto electrical work. The kit ships with the temperature sensor, wiring harness and instructions so you can replace or add a gauge without custom fabrication.

• Includes NPT 1/8" threaded sensor for direct mounting into oil galleries or adapter ports.
• Pre-wired connections for power, ground and sender signal reduce splicing.
• 52mm housing fits standard 2-inch dash openings; bezel and mounting hardware included.
• Blue LED ensures legible display in low light without additional illumination work.

What temperature range and alerts does this meter provide?

The gauge measures oil temperature between 104°F and 302°F, making it suitable for street, towing and performance use. A dedicated warning lamp illuminates above 248°F so you get a clear visual alert before temperatures reach risky levels.

• Range: 104°F to 302°F for broad operating conditions.
• Warning lamp activates above 248°F for quick attention on overheating.
• LED numeric display offers precise, repeatable readings for trend monitoring.
• Designed for oil only — not calibrated for coolant or other fluids.

Will this gauge work with my vehicle and electrical system?

The WATERWICH gauge is built around a universal 12V electrical standard, so it’s compatible with most passenger vehicles and light trucks. The included sender uses an NPT 1/8" thread, a common size for oil temp senders, but check your engine ports for fit or use an adapter where necessary.

• Power: DC 12V — standard car electrical systems supported.
• Sender thread: NPT 1/8" for common oil port compatibility.
• Fits dashboards with 52mm (2") cutouts; bezel for clean installation.
• Intended measurement unit: Fahrenheit (Celsius model available separately).

How does the illuminated display help during night driving?

The bright blue LED backlight makes the numeric display clear from many viewing angles without distracting glare. It’s designed to be visible in complete darkness and under changing light, helping you keep eyes on the road while checking oil temperature quickly.

• High-contrast blue LED improves readability at night.
• Low power draw compatible with vehicle electrical systems.
• Non-intrusive illumination keeps instrument cluster balance.
• Digital readout gives exact temperature values instead of a needle approximation.

Who is this for: This WATERWICH oil temperature gauge kit is for drivers who want dedicated oil temperature monitoring—enthusiasts tracking engine performance, technicians adding a diagnostic instrument, and owners who tow or use their vehicle under heavy load. If you need a compact, visible, accurate oil-only temperature display that installs with a standard 1/8" sender fitting and runs on 12V, this kit is designed for that purpose.
