This 3-pin coolant level sensor emulator is designed for Kenworth, Peterbilt, and Volvo VN/VNL trucks. It is not a coolant level sensor but a bypass device that enables continued operation when the truck's coolant level monitoring system is faulty. The emulator prevents engine shutdowns or power reduction due to a malfunctioning coolant sensor.
Benefits
Eliminates annoying beeping, "stop engine" warnings, and low coolant level alerts on the dashboard.
Simple installation: just connect the emulator to the existing sensor plug.
Ensures uninterrupted driving by bypassing the coolant level monitoring system.
Important Notes
Always check the coolant level during your daily pre-trip inspection to avoid engine overheating, as this emulator disables coolant level monitoring.
If the emulator does not work, it may indicate a damaged wiring harness between the coolant level sensor and the engine ECU.
Temporary Workaround Only This emulator is not a permanent repair. It is designed to get you out of a pinch and allow you to reach a mechanic without shutdown or derate. We strongly recommend replacing the faulty coolant level sensor at your earliest opportunity to restore full monitoring and protect your engine.
