Product Description

This Moca Expansion Tank with Cap is designed as a direct replacement cooling water bottle for select Mercedes-Benz models. The expansion tank plays a crucial role in your vehicle's cooling system by storing excess coolant and maintaining correct pressure, helping to prevent overheating and coolant loss. The included cap ensures a secure seal, maintaining the integrity of your cooling system.

Compatibility is specific to certain Mercedes-Benz vehicles, particularly models equipped with engines such as the M112, M272, and M113 found in the W203 and CLK C209 series. It is essential to confirm your vehicle’s model, year, engine size, and engine code before ordering to guarantee correct fitment.

Typical symptoms of a failing expansion tank include coolant leaks, visible cracks or swelling in the tank, low coolant warnings, engine overheating, or the presence of coolant odours near the engine bay. If you notice any of these signs, it could indicate that your expansion tank needs replacement.

Replace the expansion tank if you detect leaks, cracks, or if the tank is discoloured and brittle. Timely replacement helps avoid engine overheating and costly repairs caused by coolant loss or pressure issues.

Trust MiMi Auto Parts for reliable cooling system components, with nationwide delivery available throughout South Africa. Always check your vehicle details before purchasing to ensure the correct part for your Mercedes-Benz.

Typical replacement guidance
