Volkswagen Passat overheating issue causing shutdown and air conditioner failure on Volkswagen Passat

Some Volkswagen Passat owners report experiencing overheating issues that can lead to engine shutdown and air conditioner failure. These problems may arise from factors such as coolant leaks, radiator fan malfunctions, or a faulty water pump. When the warning light activates or steam is seen from the hood, it is crucial to take immediate safety precautions, including stopping the vehicle in a safe location without turning it off right away. Additionally, some owners notice cold air blowing from specific vents, like the passenger side, alongside rising engine oil temperatures, which could signal a cooling system issue. Leaks caused by damaged hoses or a worn-out water pump can result in a gradual loss of coolant, ultimately leading to overheating. Furthermore, a faulty thermostat, which is often replaced with the water pump and timing belt, may exacerbate excessive coolant temperatures. It is vital for owners to address these issues promptly to prevent significant damage and ensure the vehicle operates correctly.
