12V 24V 52mm Car Voltmeter Gauge Set | Water Temp Oil Temp Oil Pressure

Key Features

• Four-in-One Monitoring — It combines a voltmeter, water temperature gauge, oil temperature gauge and oil pressure gauge in one unit, so the engine status can be read at a glance.
• Yellow Backlight — The yellow backlight makes the readings easier to see during night driving or in dimly lit engine bays.
• Lightweight Plastic Build — The plastic housing keeps each gauge lightweight and resists corrosion.
• DC24V Diesel Design — It is designed for diesel engines running on a DC24V electrical system.

What It Is / How It Works

This 52mm gauge set is an engine monitor that combines a voltmeter, water temperature gauge, oil temperature gauge and oil pressure gauge in one unit. It is built for keeping an eye on the main readings of a diesel engine from the dash.

Who It's For / Use Cases

Gauge sets like this suit diesel truck owners who want to watch engine temperature and oil pressure on long hauls. They also fit boat operators running marine diesel engines and off-road enthusiasts upgrading a dash with engine monitoring. Mechanics and DIYers building or restoring a vehicle can use it to add a complete gauge set in one step.

How to Use / Care

1. Mechanics and DIYers fit the complete gauge set into a custom build or restoration project.
2. Confirm the system is DC24V before connecting, since the set is designed for DC24V diesel engines.
3. Check your electrical system before installation, because gasoline vehicles typically use a 12V system and compatibility may be limited.
4. Once installed, read water temperature, oil temperature, oil pressure and voltage from the single gauge set.

How to Choose

Start with the electrical system. The set is designed for DC24V diesel engines, and its voltmeter covers 8-16V and 18-32V. Confirm your vehicle's voltage before buying. Next, check the mounting space: each gauge is 52mm, a standard size for most dash panels and universal gauge pods.

Frequently Asked Questions

Does this gauge set work with a 12V system?
The voltmeter covers 8-16V, so it can read a 12V system. The gauge set is designed for DC24V diesel engines, so confirm your vehicle's voltage before purchase.

Can I install this gauge in a gasoline car?
This set is optimized for DC24V diesel engines. Gasoline vehicles typically use a 12V system, so compatibility may be limited.

Are the sensors included?
The package includes one 52mm gauge unit. Sensors for water temperature, oil temperature and oil pressure are sold separately.

Is the backlight always on or switchable?
The yellow backlight turns on when the gauge is powered and stays on while the engine is running.

How do I wire this gauge to my dashboard?
Wiring connects the power, ground and sensor wires according to your vehicle's wiring diagram. Basic electrical knowledge is recommended for proper installation.
