Detailed Fitment and Function

This engine oil pump is used in Mercedes-Benz diesel engine lubrication systems to circulate oil through the engine and maintain oil pressure. Correct oil pump selection is critical when replacing a worn or failed unit, especially on high-mileage Mercedes-Benz Sprinter 2500 and Sprinter 3500 vans or GL, ML, and R-Class vehicles that match OE No. 6421802101. Use V30-3467 when the vehicle application and OE reference align.

Common Problems This Part Can Address

• Low oil pressure warning conditions tied to pump wear
• Reduced oil circulation from a failing internal pump assembly
• Engine lubrication issues after oil pump damage or contamination
• Noisy operation associated with a worn oil pump
• Replacement during engine service when OE No. 6421802101 is specified

Installation Notes and Tips

Verify the OE number, engine code, and vehicle application before ordering. Clean the oil passages and inspect related lubrication components during installation to help prevent repeat failure. Because this is an internal engine component, installation should be performed by a qualified technician following Mercedes-Benz service procedures.
