Coolant Temperature gauge specifications

Customize your display and expand your setup

Choose a digital readout or analog-style face. Upload a 240 × 240 JPG background, or customize the analog background and needle. Set warning thresholds with visual and audible alerts.

Start with the included temperature sensor, then add compatible sensors as your setup grows. One 52mm display can show up to four readings without adding another gauge. Additional Flock sensors and adapters are sold separately.

Plan your coolant temperature gauge installation

Check the coolant sensor location, thread requirements and available clearance for your vehicle before ordering. A coolant hose adapter or other vehicle-specific fitting may be required and is sold separately. Confirm the hose size and adapter requirements for your installation.

Review the Flock Gauge user manual and car setup guides before ordering. For setup help, email hello@flock-mfg.com with your year, make, model, engine and planned sensor location.

Coolant Temperature gauge questions

Does this water temperature gauge need OBD-II?

No. This bundle uses the included dedicated temperature sensor wired directly to the gauge; it does not rely on coolant data from the ECU.

Which coolant hose adapter do I need?

That depends on your vehicle, coolant hose size and chosen sensor location. The sensor uses a 1/8 NPT thread. A suitable hose adapter or other fitting may be required and is sold separately.

Can I display coolant temperature in Fahrenheit or Celsius?

Yes. The gauge supports both °F and °C.

Can I set my own coolant temperature warning?

Yes. Set your own warning threshold with visual and audible alerts. Choose the threshold using your engine’s specifications and normal operating temperatures.

Can I add other sensor readings later?

Yes. Connect up to four compatible independent sensors and display up to four readings at once. This bundle includes one sensor. Additional sensors and installation adapters are sold separately.

What can I customize?

Choose a digital readout or analog-style face, upload a 240 × 240 JPG background, customize the analog background and needle, and set your own warning thresholds.
