🔌 Function

The gauge converts resistance from the diesel-engine temperature sender into a visible cooling-system temperature reading. It helps identify normal warm-up, thermostat behaviour and overheating.

⚠️ Common Signs of Failure

• Gauge remains cold with the engine at operating temperature
• Needle immediately moves to the hot end of the scale
• Reading fluctuates because of sender, ground or wiring faults
• Incorrect sender calibration causes an inaccurate reading
• Lens, backlighting or internal needle movement fails
