⚠️ Common Signs of Failure

• Alarm sounding with no real over-temperature behind it
• No alarm when the engine is genuinely running hot
• Alarm that comes and goes with vibration
• Terminals corroded or the seal at the unit perished
• Warning lamp or reading behaving erratically

🛠️ Service Notes

• Check the actual coolant temperature by another means before condemning the monitor - a false alarm and a real overheat look the same from the helm
• Renew the sealing washer at the sensing point and check the earth and the connector wiring
