软管在您的发动机中起着至关重要的作用，可以使冷却液，动力转向液和制动液等液体在需要的地方流动，然后再返回。大多数发动机软管都是由特殊配制的橡胶制成的，该橡胶设计为耐热。

Manufacturers use a wide range of chemicals to make the rubber used in engine hoses more heat-resistant.

软管如何抗热

In addition to the rubber’s chemical makeup, the thickness of the rubber found in engine hoses also plays an important role in resisting heat. Certain hoses, particularly those that deal with pressurized fluids are designed to be thicker as a means to combat the high pressure. These hoses can be reinforced in order to resist heat and sustain high pressure. Heat softens rubber, so reinforcement may be needed to ensure that all hoses maintain their structural integrity.

确保正确安装和路由所有软管也将有助于防止软管融化。与发动机热点接触的错误路由冷却液软管将开始融化，尽管这需要一些时间。发动机中某个点使用的错误软管也将融化，因为它的设计不是为了处理该位置的热量。

这就是为什么您必须仅在每个区域使用OEM特异性软管，从上下散热器软管到动力转向系统以及两者之间的所有内容。
