2" 52mm Water Temp Gauge 40-120 Celsius | 12V Car Temperature Meter with Sensor

Keep your gasoline engine running at the right temperature with this 52mm water temperature gauge. It measures coolant heat from 40 to 120 degrees Celsius, giving you a clear readout on a black dial with white LED lighting. The kit includes a 1/8 NPT thread sensor for easy installation in most 12V vehicles.

This gauge is built for drivers who want a simple, reliable way to monitor engine temperature. The 52mm round housing fits standard dash pods or mounting panels. White LED backlighting makes the needle and numbers easy to see at night, so you can spot temperature changes quickly while driving.

The included sensor uses a standard 1/8 NPT thread, which fits many common engine ports. Just connect the wiring to your 12V power source, install the sensor in the cooling system, and you are ready to go. The gauge runs on 12V DC power, typical for most gasoline cars.

Whether you are upgrading an older dashboard or adding a temperature monitor to a project car, this gauge gives you the data you need. The plastic housing keeps it lightweight, and the simple black design blends with most interior styles.

Key Features and Benefits

- 52mm round dial that fits standard 2-inch gauge pods for a clean dashboard installation

• 40-120 degree Celsius range that covers normal operating temperatures for most gasoline engines

• White LED backlight that makes the gauge readable in low-light or nighttime driving conditions

• 1/8 NPT sensor thread that matches common engine port sizes for straightforward mounting

• Plastic housing and lightweight design at 130g that reduces strain on mounting brackets

• 12V DC power compatibility that works with standard gasoline car electrical systems

Who Is This For

- Car enthusiasts who are replacing a broken or inaccurate factory temperature gauge

• DIY mechanics building a custom dashboard or upgrading an older vehicle

• Project car owners who need a simple temperature readout for engine tuning or monitoring

• Drivers who want a backup gauge to cross-check readings from their main instrument cluster

Usage Scenario

Mark drives a 1990s pickup that he is restoring in his garage. The original temperature gauge stopped working years ago, so he had no way to know if the engine was overheating. He installed this 52mm gauge in an empty dash slot, connected the sensor to the thermostat housing, and wired it to a 12V source. Now he sees the coolant temperature climb steadily after a cold start and settle in the normal range during highway driving. When the needle moves above 100 degrees in stop-and-go traffic, he knows to pull over and check the cooling system before any damage happens.

Micro Comparison

Unlike digital gauges that require extra wiring or adapter kits, this analog gauge uses a straightforward 1/8 NPT sensor and simple two-wire power connection. The white LED backlight provides clear visibility without the glare or complexity of multi-color displays. If you prefer a no-fuss mechanical-style readout that works with standard 12V systems, this gauge is a practical choice.
