⚙️ Key Features

• 80 degrees C switching temperature
• 0.025 kg
• 129 applications across MD, TMD, TAMD, AD, D and AQ series

🔌 Function

Closes the alarm circuit when the monitored temperature reaches 80 degrees C, so overheating is signalled before damage is done.

⚠️ Common Signs of Failure

• Overheat alarm never sounding, even on a hot engine
• Alarm sounding when the engine is plainly cool
• Intermittent alarm as the boat moves, from a poor connection
• Body or thread corroded, weeping coolant
• Terminal broken away or badly corroded

🛠️ Service Notes

• Life-safety monitoring: an overheat alarm that has not been proved cannot be trusted, so test it with the alarm test circuit
• Confirm the 80 degrees C rating against the fitted unit before ordering
• Check the wiring and earth first, and fit into a clean, sealed port so the sensing tip sees coolant

📦 Condition

• Genuine Volvo Penta part
