ESUPPORT 2" (52mm) Digital Water Temp Gauge – Fahrenheit Readout with Overheat Warning Light

ESUPPORT's 2" (52mm) digital water temperature gauge displays engine coolant temperature in Fahrenheit with a built-in warning light for high-temperature alerts. This compact 52mm gauge provides a clear digital readout and a visible overheat indicator designed for cars and light vehicles. It runs on standard 12V vehicle power, accepts an NPT 1/8" sensor thread, and measures coolant temperatures from 104°F up to 300°F—suitable for monitoring normal operating range and spotting overheating before it causes damage.

How will this gauge fit into my vehicle's dashboard?

The 2-inch diameter matches common aftermarket pod openings, making it straightforward to mount in most dashboard or pillar pods. Its electrical connections are compatible with 10–15V DC systems, so it installs cleanly in typical 12V cars and trucks.

• Face diameter: 2" (52mm) standard sizing for pods and mounts
• Power: DC 10–15V, optimized for 12V systems
• Sensor mounting: NPT 1/8" thread for common temperature senders
• Compact depth for easier dash clearance and wiring

What temperatures does the gauge display and how is overheating indicated?

The gauge reports water/coolant temperature in Fahrenheit across a broad operating band from 104°F to 300°F. If coolant temperature exceeds 212°F, the integrated warning light activates to alert you visually so you can take prompt action.

• Readout range: 104–300 °F for everyday and extreme conditions
• Warning light triggers at temperatures above 212 °F
• Immediate visual alert reduces risk of unnoticed overheating
• Ideal for both daily drivers and performance vehicles monitoring cooling systems

What are the installation and sensor connection details?

Installation requires a sender with an NPT 1/8" thread and simple 12V wiring to power the display and warning circuit. The unit is built for professional-style installations but can be fitted by a competent DIYer following wiring diagrams and using proper sealing at the sender port.

• Sensor thread: NPT 1/8"—compatible with standard temperature senders
• Electrical: DC 10–15V supply, ground, and optional illumination circuit
• Mounting: 52mm panel cutout; clamp or pod installation methods common
• Sealing: use proper thread sealant or Teflon tape at sender connections

How will this gauge help me while driving or racing?

Keeping a continuous, accurate coolant temperature readout helps you detect trends that precede failure, such as slow overheating or sudden spikes under load. The prominent warning light gives an immediate visual cue, so you can safely pull over or reduce load before severe engine damage occurs.

• Digital clarity lets you read temperature at a glance during driving
• Warning light provides rapid notification of dangerous temperatures
• Wide range accommodates street and high-performance conditions
• Useful for tuning, towing, and track-day monitoring

Who is this for? This ESUPPORT 2" digital water temperature gauge suits car owners, mechanics, and motorsport enthusiasts who want reliable coolant monitoring in a compact package. It's particularly useful for drivers who tow, race, or simply want earlier warning of cooling system issues; installers and DIYers will appreciate the standard 52mm size and NPT 1/8" sensor compatibility for straightforward integration into most vehicles.
