• Noise from worn pump bearings
• Coolant flow issues related to impeller wear or damage
• Service replacement for a pump with the wrong hose-connection configuration

Installation Notes

Confirm engine code, VIN break, and hose-connection layout before installation. Clean the mounting surface thoroughly, inspect adjacent cooling-system components, and replace the gasket supplied with the pump during assembly. After installation, refill and bleed the cooling system according to Mercedes-Benz service procedures to remove trapped air and verify stable operating temperature.
