Mercedes 300SD Replacement Expansion Tank Information


While the expansion tank on your Mercedes 300SD is not a critical part that contributes to your vehicle's performance, it's an important part of the engine cooling setup that provides a termination point for a close-looped system. The expansion tank collects the overflow radiator fluid/coolant when it has reached boiling temperature and must escape the confines of engine/radiator system. Without an expansion tank, this pressurized, boiling liquid would simply have no place to go, short of blowing out a hose or the radiator cap. A cracked or broken expansion tank isn't quite as bad as no tank at all, but a leaky tank will allow coolant to flow to the ground, requiring vigilance in continually keeping the system topped up. A replacement operation is neither expensive nor difficult. Parts Geek has the part, designed to fit 1978-1993 Mercedes 300SD sedans, from manufacturers including Genuine, the original part maker.
