Крышка бака охлаждающей жидкости двигателя Caterpillar 3937218

An Engine Coolant Tank Cap seals the coolant reservoir, ensuring that the coolant remains within the system and is not lost through evaporation or leakage. By maintaining the necessary pressure within the cooling system, the cap helps prevent overheating and ensures that the engine operates at optimal temperatures. The unvented design of this cap is required to prevent external contaminants from entering the coolant system, thereby maintaining the purity and efficiency of the coolant.Attributes:• Ensures a secure seal on the coolant reservoir.• Withstands high temperatures and pressures.• Unvented design prevents external contaminants from entering.Applications: An Engine Coolant Tank Cap is positioned on top of the coolant reservoir within the equipment's engine compartment to seal the coolant tank, preventing the coolant from evaporating or becoming contaminated.
