Mercedes Sprinter Coolant Regulation Valve – Genuine OEM | VS30 2.0L Diesel | #0005061500 (2019+)

A failed coolant regulation valve on a VS30 Sprinter disrupts the low-temperature cooling circuit — causing unpredictable engine temperatures, poor heater performance, and fault codes that won't clear until the valve is replaced. This is the Genuine Mercedes-Benz OEM coolant regulation valve for VS30 Sprinters equipped with the 2.0L diesel engine, a direct plug-and-play replacement that restores precise coolant flow control across the full cooling circuit.

What This Part Does

The coolant regulation valve — also called a low-temperature circuit switchover valve — controls coolant routing between the engine, heater core, and low-temperature cooler based on demand signals from the powertrain control unit. It directs coolant flow to bring the engine up to operating temperature quickly, maintain a stable thermal range under load, and deliver consistent heat to the cabin. When the valve sticks open, closed, or fails electrically, the cooling system loses the ability to regulate flow correctly — resulting in temperature swings, heater output loss, and active fault codes logged against the coolant directional control valve circuit.

Common Symptoms of a Failing Coolant Regulation Valve

• Fault message or warning light related to the coolant directional control valve (Y73/1)
• Engine slow to reach operating temperature or running cooler than normal
• Heater output that is weak, delayed, or inconsistent
• Engine temperature fluctuating during highway or load operation
• Cooling system fault codes that return after clearing

When to Replace

Replace when the valve is confirmed stuck, inoperative, or logging active faults through XENTRY or a compatible scan tool. Also replace when symptoms of improper coolant routing persist after ruling out other cooling system components.

VS30 2.0L Specific — VIN Verification Required

This valve is for VS30 Sprinters equipped with the 2.0L diesel engine. It is not confirmed compatible with VS30 models equipped with the 3.0L OM642 or NCV3 (2007–2018) Sprinters. Always verify your engine code and VIN before ordering. Contact us and we'll confirm fitment before you buy.
