Moisture in the system. it may just be condensation or it may be more serious, as in a blown head gasket. If you are not loosing coolant, then you may not have a serious problem. If, however you are loosing coolant, you may have a blown head gasket. Either way, have it looked at by a professional. Serious engine damage can occur if it is coolant in the combustion chamber.

The chain under the oil cap is typically referred to as the "oil cap chain" or "oil fill cap chain." This chain connects the oil cap to the engine or valve cover, preventing the cap from being lost or dropped during maintenance. It's a small but important feature that helps maintain engine cleanliness and safety.
