求翻译：发动机冷却液的主要作用就是冷却发动机部件、防止冷却液凝固、防止冷却系统部件生锈、防止过热。随着随着汽车发动机技术的飞速发展，对发动机冷却液的要求日益苛刻，因而发动机冷却液的改型换代也正在加速进行。汽车工业近年来的发展趋势是发动机功率越来越大，而为减小风阻系数，普遍采用流线外型，是什么意思？

The main role of the engine coolant is cooled engine parts, to prevent the coolant freezing, cooling system parts to prevent rust and prevent overheating. As with the rapid development of automobile engine technology, the engine coolant becomes more demanding, which modified the engine cooling fluid

engine cooling liquid cooling engine components is the main role, prevent cooling liquid cooling systems components concretion, prevent rust and prevent it from overheating. With the rapid development of technology as the automobile engine, the engine coolant of increasingly stringent requirements,

The engine refrigerant main function is cools the engine part, prevented the refrigerant coagulates, prevented the cooling system part rusts, prevents superheat.Along with along with the motor car engine technology rapid development, is day by day harsh to the engine refrigerant request, thus the en

Main effect of the engine coolant is cooled engine parts, preventing cooling solidification, cooling system parts Rust prevention, prevent it from overheating. As with the rapid development of automobile engine technology, increasingly demanding requirements of the engine coolant, and modification o
