Mercedes Sprinter Coolant Level Sensor – Hudson | NCV3 & VS30 | #2205450024 (2007–2024)

A failed coolant level sensor on a Mercedes Sprinter prevents the low coolant warning from activating when the coolant level drops — removing the early warning that gives the driver time to add coolant before an overheating event damages the engine. This is the Hudson coolant level sensor for NCV3 and VS30 Sprinters, a direct replacement that restores accurate coolant reservoir level monitoring and proper dashboard warning function.

What This Part Does

The coolant level sensor is a float-type or conductivity-based sensor mounted in the coolant reservoir. It monitors the coolant level and signals the instrument cluster warning system when the level drops below the minimum threshold. On the Sprinter, the warning activates as a dashboard light that alerts the driver before the cooling system loses enough fluid to compromise temperature regulation. When the sensor's float mechanism fails, its contacts corrode, or its wiring develops a fault, the warning either stays on regardless of coolant level or fails to activate when the level genuinely drops — both situations compromising the driver's ability to respond appropriately to coolant loss.

Common Symptoms of a Failing Coolant Level Sensor

• Low coolant warning light that stays on despite the reservoir being full — sensor fault, not low coolant
• No warning light when coolant is genuinely low — sensor has failed to open circuit
• Intermittent warning light that activates and clears unpredictably
• Sensor body found corroded, cracked, or physically damaged during reservoir inspection

When to Replace

Replace when the warning light behavior doesn't match actual coolant level and the sensor is confirmed faulty. Always verify actual coolant level before diagnosing the sensor as the fault source.

VIN Verification Required

Coolant level sensor configurations vary by reservoir design and model year. Always verify by VIN before ordering. Contact us and we'll confirm fitment before you buy.
