Key Features

• Direct fit replacement: Built as a direct match for the original reservoir to avoid modifications during installation and save time.
• Broad compatibility: Fits a range of Mercedes Benz models including S430, S500, CL500, G500 and AMG variants from the early 2000s, reducing the risk of misfit when the vehicle is listed in the chart.

• Reference numbers provided: Includes part references 2205000049, 603-633, and 671-50454 to help confirm compatibility with parts diagrams and repair guides.

Who It's For

This reservoir is aimed at Mercedes Benz owners and independent mechanics working on 2000 to 2006 S-class and CL models, 2001 to 2008 G-class models, and several AMG variants listed in the fitment. It is especially useful for DIYers who prefer a pre-assembled, direct-fit replacement and who consult online fitment charts before ordering.

It is not intended for vehicles outside the listed fitment or for users who need OEM branding or original equipment certification; confirm fitment carefully with the vehicle compatibility chart before purchase.
