Radiator and Oil and Fuel Caps

The radiator cap is a pressure-sealing cap on the radiator of an engine cooling system and the oil cap seals the opening where engine oil is added, while the fuel cap seals the fuel tank opening. Radiator, oil, and fuel caps are critical for maintaining the engine's operational integrity. The radiator cap ensures the engine stays cool, the oil cap keeps the lubrication system clean and efficient, and the fuel cap maintains fuel quality and pressure. Without these caps, the engine is at risk of overheating, contamination, and fuel loss, leading to reduced performance and potential engine failure.
