Some INFINITI M35 owners report experiencing overheating issues accompanied by reddish oil leaks and stalling. Common factors contributing to these problems include coolant leaks, which may arise from a faulty water pump, radiator, or hoses, leading to significant overheating. Additionally, engine oil leaks are particularly noted in the 2008 model, with oil seeping from various components that, if left unchecked, can cause serious engine damage. Faulty thermostats can also contribute to overheating, making it important to check and potentially replace this component. Overheating while idling or at low speeds may indicate clogged radiator issues or inadequate water pump flow. Furthermore, low coolant levels can quickly lead to engine overheating, underscoring the necessity of regularly checking coolant levels. To resolve these issues, owners are advised to inspect for coolant and oil leaks, assess the condition of the water pump, radiator, and hoses, and ensure proper coolant levels, potentially seeking professional diagnosis and repair for underlying problems.
