Product Details

VAICO line components are built for direct replacement use in European vehicle cooling systems, and this water pump follows that approach with an OE-style mechanical design.

Part number V30-50039 is listed for multiple Mercedes-Benz platforms, including 1998-2005 Mercedes-Benz E320, 2002-2008 Mercedes-Benz G500, and 2002-2007 Mercedes-Benz ML500.

Common Cooling System Issues It May Address

• Coolant leakage from the water pump housing or seal area
• Overheating caused by reduced coolant circulation

Installation Notes and Tips

Verify engine code, chassis break points, and oil cooler fitting requirements before ordering, especially on Mercedes-Benz E320, CLK320, and SLK320 applications. Replace the pump only after confirming the correct fitment by year, model, and engine configuration. Clean the mounting surface thoroughly and inspect the cooling system, belts, hoses, and thermostat during service to help prevent repeat repairs.
