Water Pump - Inspect
失效的水泵可能引起严重的发动机过热问题，进而导致以下情况：
- 缸盖裂纹
- 活塞咬缸
- 其它对发动机的潜在损害
注: 水泵密封由冷却系统的冷却液进行润滑。 水泵可能会出现少量冷却液泄漏，此为正常现象，这是因为发动机冷却和零件收缩的原因。
目视检查水泵是否泄漏。
注: 如果冷却液进入发动机润滑系统，必须更换机油和发动机机油滤清器。 更换机油和发动机机油滤清器可清除因冷却液导致的所有污染。 更换机油和发动机机油滤清器可防止所有不规则的油样。
水泵属于不可维修项目。 要安装新的水泵，请参阅拆解和装配手册, "水泵 - 拆卸和安装"或联系您的 Cat 代理商。
