Show original supplier description

This OEM-quality part ensures proper functionality and integration with your vehicle's existing cooling and climate control setup. The pump is backed by a 2-year warranty, providing peace of mind for its durability and performance. This auxiliary water pump is compatible with a wide range of Mercedes-Benz models, including various CLS-Class, E-Class, G-Class, GL-Class, ML-Class, and R-Class vehicles, as well as Sprinter vans. It is essential to verify fitment for your specific year, model, and engine configuration. Important fitment notes apply: The pump is not compatible with cars that have the Auxiliary Heater (Code 228) on certain CLS and E-Class AMG models. Additionally, some R-Class models require Rear Air Conditioning (Code 582) for proper fitment. The brand does not include the mounting bushing with this part.
