Problem overview

Some Mercury Sable owners report experiencing coolant leakage between the engine block and front cover near the water pump, which can be attributed to several common issues. These include faulty water pumps that lead to leaks, damage to the radiator causing coolant to escape, and worn or frayed hoses contributing to the problem. Additionally, some owners face head gasket leaks and intake manifold leaks that also result in coolant leakage. It is crucial for owners to address these potential causes promptly to prevent significant coolant loss and avoid further damage to the vehicle. If steam is observed due to the leakage, it is recommended to have the issue diagnosed and repaired by a qualified mechanic to ensure the vehicle's proper functioning.
