Coolant disappearance could indicate a leak in the radiator, hoses, or water pump. Check for puddles under your vehicle or a sweet smell, suggesting coolant leakage. It may also be due to a head gasket failure, causing coolant to mix with engine oil. Look for white smoke from the exhaust or milky oil. Regularly inspect and maintain your cooling system to prevent serious engine damage (a professional mechanic should check for leaks if unsure). Prompt action ensures your vehicle runs smoothly and safely.
