Volvo S80 anti-freeze disappearing with engine overheating and check engine light issue on Volvo S80

Some Volvo S80 owners report experiencing issues such as disappearing anti-freeze, engine overheating, and a check engine light activation. These problems may indicate potential coolant leaks, which can lead to overheating and severe engine damage if not addressed promptly. Additionally, a malfunctioning thermostat can prevent coolant from reaching the radiator, exacerbating overheating issues. Owners also note that the check engine light should be addressed immediately to avoid further vehicle damage. Regular visual inspections and pressure testing of the cooling system are recommended to identify leaks and other issues early, helping to prevent engine overheating and coolant loss.
