The 2118350364 auxiliary coolant / water pump is a used OEM Mercedes part, removed from a 4.0L twin-turbo V8 C63 AMG. This electric pump keeps coolant flowing through the turbocharger system after shutdown to prevent heat soak, and it supports cabin heat when the engine is off. A failing unit may cause intermittent low coolant warning lights, reduced heater output, or turbo overheating after a hot restart. Also known as an auxiliary water pump, it’s a common wear item on high-performance turbocharged engines.
