Mercedes-Benz CL550 radiator fluid leaking with engine shutdown issue on Mercedes-Benz CL550

Some Mercedes-Benz CL550 owners report experiencing coolant leaks, which can originate from various sources such as the radiator, hoses, water pump, or coolant reservoir. These leaks may manifest as green or orange fluid under the vehicle, indicating a potential radiator issue. In some instances, the leak may not be immediately visible, necessitating a thorough inspection of the cooling system components. Additionally, some owners have noted that engine shutdown problems could be linked to overheating caused by these coolant leaks, highlighting the urgency of addressing the issue promptly. Specific models, like those with the OM651 CDI engine, may also face known issues with the filter housing that can lead to leaks, which can be remedied by replacing the housing with a three-bolt version. It is recommended for owners to consult a qualified mechanic or Mercedes-Benz service center to effectively diagnose and repair these coolant leaks and engine shutdown concerns to ensure the vehicle's performance and longevity.
