Coolant Expansion Tank for Mercedes-Benz W204 C-Class & W212 E-Class (A2045000749)

If your Mercedes keeps losing coolant, has a sweet smell after a drive, or shows white crust around the coolant bottle, the expansion tank is often the problem. On the W204 and W212, the plastic tank gets brittle from years of heat, and fine cracks start to leak under pressure. This replacement tank, part number A2045000749, fits the C-Class W204 and E-Class W212 with no drilling or modifications. The tank holds the extra coolant that expands as the engine heats up, then lets it flow back as the engine cools. A leaking tank lets the system lose pressure and coolant level. Leave it too long and you risk overheating, which costs far more to fix than the tank. Fitting it is a straightforward job for most mechanics. Let the engine cool completely before opening the cooling system. Once the new tank is in, refill with the correct Mercedes-approved coolant and bleed out any air. Not sure it fits your car?
