Крышка горловины заливки охлаждающей жидкости расширительного бака Caterpillar 2682889

An Expansion Tank Coolant Filler Cap closes the opening of the expansion tank while regulating the pressure within the cooling system. Maintaining correct pressure helps raise the boiling point of coolant, allowing the engine to operate efficiently without overheating. The cap prevents coolant loss by forming a tight seal, while also ensuring excess pressure is safely released to avoid damage to hoses. Keep coolant circulating properly, ensuring consistent engine temperature and improved performance.Attributes:• Retains coolant volume for effective thermal regulation.• Withstands frequent heating and cooling cycles without seal failure.• Minimizes strain on connected coolant hoses and fittings.Applications: An Expansion Tank Coolant Filler Cap is fitted onto the expansion tank of the engine cooling system, sealing the coolant reservoir and regulating system pressure during operation.
