Coolant loss from the reservoir can be caused by several issues. Check for leaks in the hoses, radiator, or water pump, as they are common culprits. A faulty radiator cap can also lead to coolant escaping. Over time, the cap may lose its ability to maintain the right pressure. Additionally, inspect for signs of a blown head gasket, which can cause coolant to mix with engine oil or escape through the exhaust. To prevent engine damage, address these issues promptly with a mechanic's help.
