Product Description

This Cooltec radiator hose to expansion tank is designed for the cooling system of select Mercedes-Benz models. It serves as a crucial link, allowing coolant to flow between the radiator and the expansion tank, helping to regulate engine temperature and prevent overheating. The hose features robust end fittings, including a quick-connect plastic fitting and a secure metal collar, along with a protective mesh sleeve for added durability in the engine bay environment.

This part is compatible with Mercedes-Benz vehicles, specifically models in the W204 series with M271 and M272 engines. To ensure a proper fit, always confirm your vehicle's model, year, engine size, and engine code before placing an order.

Symptoms of a failing radiator to expansion tank hose may include visible coolant leaks, low coolant levels, overheating, swelling or softening of the hose, engine temperature warning lights, and the presence of cracks or splits along the hose. You might also notice a sweet smell from leaking coolant or steam coming from the engine bay.

If you notice any of these symptoms, it is important to inspect and replace the hose promptly to avoid further damage to your engine. Always ensure the engine is cool before attempting any work on the cooling system, and consider replacing associated clamps or connectors during installation for a secure seal.

MiMi Auto Parts is committed to supplying reliable parts for your Mercedes-Benz, with nationwide delivery available across South Africa. For peace of mind and the correct fit, consult our team if you have any questions before ordering.
