Mercedes Sprinter Water Pump Assembly – GPM | VS30 2.0L OM654 Diesel | #6542000501 (2023+)

A failing water pump on a VS30 Sprinter will quietly drain your cooling system's ability to manage heat — starting with weeping coolant from the shaft seal and ending with an overheating engine that can cause head gasket failure or worse before you see it coming. This is the Genuine Mercedes-Benz OEM water pump assembly for VS30 Sprinters equipped with the 2.0L OM654 diesel engine, a direct replacement that restores factory coolant flow, sealing, and long-term cooling system reliability.

What This Part Does

The water pump is the mechanical heart of the cooling system. Driven by the serpentine belt, it continuously circulates coolant from the radiator through the engine block, cylinder head, heater core, turbocharger, and back — maintaining the thermal balance the OM654 depends on for efficient combustion, emissions compliance, and component longevity. The assembly includes the pump housing, impeller, bearing, and shaft seal as a complete unit. When the shaft seal fails, coolant weeps from the pump body; when the bearing wears, it produces a grinding or rumbling noise; when the impeller erodes or cracks, coolant flow drops below what the engine needs under load. Any of these failure modes leads to overheating if left unaddressed.

Common Symptoms of a Failing Water Pump

• Coolant leak or dried residue at the front of the engine near the pump housing
• Grinding, rumbling, or whining from the accessory drive area that changes with engine RPM
• Engine temperature rising above normal, especially under load or in slow traffic
• Heater output reduced or inconsistent — a sign of low coolant flow through the heater core
• Low coolant warning with no visible external hose or radiator leak

When to Replace

Replace when the shaft seal is confirmed weeping, when the bearing produces noise, or when coolant flow is suspected to be reduced and other causes have been ruled out. Also replace as part of a major cooling system service — the pump is a belt-driven wear item and should be replaced together with the serpentine belt, tensioner, and idler pulley to avoid a repeat labor job.
