22716771 Sensor Kit | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta coolant-level sensor package installed in the expansion tank of selected TWD16 generating-set engines. The sensor monitors coolant level and supplies the engine-management system with the signal used for low-coolant warning and protective action.

🔌 Function

The sensor detects whether coolant is present at the calibrated level in the expansion tank and sends the corresponding signal to the engine control and alarm system.

⚠️ Common Signs of Failure

• False low-coolant warning with the tank correctly filled
• No warning when the coolant level is below specification
• Intermittent alarm caused by damaged wiring or poor terminal contact
• Open-circuit or short-circuit coolant-level fault
• Coolant leakage around the sensor seal or expansion-tank mounting point

🛠️ Service Notes

• This is a coolant-level sensor for the expansion tank, not a temperature sensor — confirm which function the warning is reporting before ordering
• Fitment is limited to TWD16/TWD17/TWG generating-set engines, and only in one- or two-circuit cooling arrangements — check which circuit layout the set uses before assuming this part applies
• The part has already been through two supersessions (22347431 → 22664489 → 22716771) — on an older set, check the alarm panel wiring matches the current sensor before fitting
