OVERVIEW
Restore coolant circulation with the correct pump section
Genuine VW/Audi 06K-121-011-C is the mechanical water pump section for the matching engine cooling assembly. Its impeller circulates coolant through the engine and cooling circuit when driven by the original mechanism.
The pictured pump has a metal housing, an impeller and a shaped sealing interface. Identify the pump section separately from the thermostat and coolant control housing when planning the repair.
Technical details
- Complete factory number: 06K-121-011-C.
- Factory specification: factory engine water pump section, number 06K-121-011-C.
- Design: metal pump housing with impeller and matching perimeter seal profile.
- Quantity supplied: one individual water pump section; thermostat housing, drive belt, coolant and other service hardware are separate unless specified in the supplied package.
EA888 engines use several pump and thermostat revisions. A later complete housing assembly may contain additional components, so compare the original pump, housing interface and complete factory number before selecting the repair parts.
Common reasons to replace
- Testing identifies coolant leakage at the pump or its sealing interface.
- The pump bearing or drive mechanism shows wear or damage.
- Inspection confirms an impeller or pump fault that reduces coolant circulation.
Overheating and coolant loss can also result from a thermostat fault, damaged housing, hose leak or another cooling-system problem. Diagnose the source and inspect the adjoining housing and drive components before replacing the pump.

Installation guidance
Allow the engine to cool completely and follow the factory cooling-system service procedure. Prepare the sealing faces without damaging them, fit the correct seal and hardware, and use the prescribed tightening sequence and specifications.
Refill with the correct approved coolant mixture and complete the specified filling and air removal procedure. Check for leaks and verify operating temperature and coolant circulation after service.
