Gauge and adapter for 12 V cooling systems
The Dyno Racing 2" 52 mm water-temperature gauge measures coolant from 40 to 120 °C and is designed for 12 V DC electrical systems drawing up to 0.3 A. A white LED backlight illuminates the black face so the pointer and numbers remain readable in darkness. The package includes a 1/8 NPT sensor, a 30 mm joint pipe, two stainless-steel clamps and English instructions.
Passive analog operation with LED backlight
The gauge uses a mechanical pointer driven by the supplied sensor, so it adds no active cooling load and generates no fan noise. Power consumption is limited to 0.3 A at 12 V, placing minimal demand on the vehicle charging system. The white LED dial light operates only when the ignition is on, providing visibility without contributing to parasitic draw.
Direct-fit sensor and hose adapter for simple
A 1/8 NPT threaded sensor screws into an available port on the engine or radiator, while the 30 mm joint pipe clamps onto the existing coolant hose using the two supplied stainless-steel clamps. The adapter’s internal diameter suits hoses near 27 mm, and the supplier notes that 28, 32, 34, 36, 38, 40 and 42 mm sizes are also available if a different fit is required.

Questions about this item
How do I install the 30mm joint pipe and 1/8 NPT sensor, and what step do people often get wrong?
Fit the 30mm joint pipe into the radiator hose using the two supplied clamps, then thread the 1/8 NPT sensor into the adapter; the step often missed is choosing a joint pipe slightly larger than the hose internal diameter — for example a 28mm pipe for a 27mm hose — to allow for hose elasticity.
What maintenance or replacement will this gauge need later?
The white LED backlight runs on 12 V DC at up to .3 A and will dim over time; the 1/8 NPT sensor can corrode or drift, so plan to replace the sensor or the whole gauge if readings become unreliable.
What limit appears first during sustained high-temperature running?
The gauge reads up to 120 °C; once coolant temperature reaches that point the pointer hits the end of its scale and can no longer show further rises.
