发动机冷却系统的材料一般来说:缸体、缸盖、进气歧管、水泵和出水管选用铸铁或铸铝合金制造,而散热器和加热器芯子多以铜或铝制做。当用铜芯子时,常采用高铅焊接。芯孔塞、水泵壳闷头等小件则常用冲压钢材。连接发动机与散热器及加热器芯子的连接软管,一般用乙丙烯二烃单体(EPMD)之类的合成材料制造。硬塑料,如高密度聚乙烯及增强尼龙则越来越多地用 Engine cooling system materials generally speaking: cylinder block, cylinder head, intake manifold, pump and outlet pipe made of cast iron or cast aluminum alloy, and radiator and heater core mostly made of copper or aluminum. When using copper core, often using high-lead welding. Core plug, pump casing bulkheads are commonly used stamping steel. Connecting hoses connecting the engine to the radiator and the heater core are typically made of synthetic materials such as ethylene propylene diene monomer (EPMD). Hard plastics, such as high-density polyethylene and reinforced nylon are increasingly used
