⚙️ Key Features

• 0.041 kg
• 43 applications
• Supersedes 841890, formerly catalogued as a switch
• Instruments group

🔌 Function

Watches temperature and changes state at its set point, driving the warning circuit so an overheat is signalled before damage is done.

⚠️ Common Signs of Failure

• Overheat alarm sounding with no rise in the gauge reading
• Alarm that never sounds even when the engine runs hot
• Warning lamp flickering with vibration
• Corrosion or weeping at the sensing thread
• Connector terminals green, loose or arced

🛠️ Service Notes

• Because the number it replaces was listed as a switch, check the thread and terminal arrangement against what is on the engine before ordering
• Verify the actual temperature with a separate gauge before condemning the monitor, and never disable an overheat alarm to silence it
