Visual Inspection
冷却系统如果不进行定期检查就会引起发动机温度升高。 在用测试设备进行测试之前，先对冷却系统进行目视检查。
- 检查冷却系统中的冷却液液位。 读取位于散热器上端的两个冷却液液位指示仪指示的液位位置。
- 查看冷却系统有无渗漏。
- 查看散热器芯上有无弯折的散热片或波折的散热器芯之间有无碎屑。 确保通过散热器的气流畅通。
- 检查风扇叶片是否损坏。
- 发动机冷却后，缓慢取下加注口盖。 这会使冷却系统内的所有压力释放出来。 检查加注口盖和气密封表面。 该表面必须清洁，密封必须无损。

逸出的带压液体可能导致人身伤害。 如果压力表上显示有压力值，从散热器上拆卸任何软管之前，应先按压放气阀油泵是否压力。 |
- 检查压力安全阀。 此阀的安全压力为105 to 125 kPa (15 to 18 psi)。
- 查看冷却系统是否有空气或燃烧气体。
