52mm Car Gauge Set | Water Temperature Oil Level Voltmeter Fuel Pressure Meter

Keep your vehicle's vital systems in check with this 52mm car gauge set. It monitors water temperature, oil pressure, fuel level, and voltage in one compact package. Each gauge provides real-time data so you can spot problems before they turn into costly repairs.

This multi-gauge system is built for drivers who want full control over their engine's health. The water temperature gauge covers 0-120℃ with a flash alarm at 96℃ or higher. The oil pressure gauge measures 0-1.00 Mpa and alerts you when pressure drops to 0.08 Mpa or below. The fuel level gauge reads 0-100% and flashes a warning at 10% or lower. The voltmeter monitors your electrical system from 9-35V and triggers alarms for low voltage, mid-range fluctuations, or over-voltage conditions.

Installation is straightforward with color-coded wiring. Each gauge uses a red wire for power positive, a black wire for power negative, and specific sensor wires where needed. The package includes the necessary sensors for water temperature and oil pressure, both with 1/8NPT threads. All gauges operate on a wide 9-35V working voltage range, making them suitable for most 12V and 24V vehicles.

Whether you drive a daily commuter, a weekend project car, or a heavy-duty truck, this gauge set gives you the information you need to drive with confidence. The 52mm size fits standard gauge pods and dash openings.

Key Features and Benefits

- Four-in-one monitoring system that tracks water temperature, oil pressure, fuel level, and voltage in a single setup

• Built-in flash alarms for critical thresholds that alert you to potential engine or electrical issues

• Wide 9-35V working voltage range that works with both 12V and 24V vehicle electrical systems

• 1/8NPT sensor threads for water temperature and oil pressure that fit common engine ports

• Color-coded wiring harness that simplifies installation and reduces connection errors

Who Is This For

- DIY car enthusiasts who install and monitor their own vehicle gauges

• Owners of older vehicles without factory gauge packages who want full engine data

• Truck and van drivers who need reliable monitoring for long hauls or heavy loads

• Mechanics and technicians looking for a complete gauge solution for customer vehicles

Usage Scenario

Mark drives a 1998 pickup truck he uses for weekend camping trips. The factory dashboard only had a speedometer and fuel gauge. After installing this 52mm gauge set, he noticed the water temperature creeping up during a steep mountain climb. The flash alarm at 96℃ warned him early. He pulled over, let the engine cool, and found a loose radiator hose clamp. Without the gauge, he would have kept driving and risked overheating the engine miles from the nearest town.

Micro Comparison

Many single-function gauges require separate purchases for each system you want to monitor. This set bundles four essential gauges together with the necessary sensors, saving you time and money. The flash alarm feature gives you an extra layer of safety that basic analog gauges do not offer. If you want complete engine and electrical monitoring in one installation, this kit delivers everything you need.

Questions and Answers

Question: Will this gauge set work in a 12V car?

Answer: Yes, all four gauges operate on 9-35V, so they work in both 12V and 24V vehicles.

Question: Does the fuel level gauge work with any fuel tank sender?

Answer: It works with sensors that have a resistance range of 0-190 ohms. Check your vehicle's sender resistance before installing.

Question: What size hole do I need to mount these gauges?

Answer: Each gauge has a 52mm diameter, so you need a 52mm mounting hole or a standard 52mm gauge pod.

Question: How do I wire the water temperature gauge?

Answer: Connect the red wire to a 12V or 24V power positive, black wire to power negative, and attach the sensor wire to the included 1/8NPT water temperature sensor.

Question: Does the oil pressure gauge come with a sensor?

Answer: Yes, the package includes a 1/8NPT oil pressure sensor for the oil pressure gauge.
