Cooling System Water Temperature Regulator - Replace
在水温调节器失效之前便将其更换掉。 这是推荐的预防性保养的做法。 更换节温器可减少可能发生的计划外停工。
节温器在部分开启位置失效时，会引起发动机过热或过冷。
水温调节器在完全关闭位置失效时，会引起发动机严重过热。 发动机严重过热会引起气缸盖开裂或活塞卡缸故障。
节温器在开启位置失效时，会引起发动机在部分负荷运行时工作温度过低。 发动机部分负载时工作温度过低会导致气缸内积碳过多。 过多的积碳可能会导致活塞环磨损加剧和缸套的磨损。

不定期更换水温调节器会引起发动机严重损坏。 卡特彼勒发动机的冷却系统包括有分流设计，此种设计要求在安装了水温调节器的情况下运行发动机。 如果水温调节器安装不正确，发动机可能过热，造成气缸盖损坏。 确保新的水温调节器安装在原来的位置。 确保水温调节器的放气孔畅通。 不要在密封垫或缸盖表面上使用液体垫片材料。 |
请参阅拆卸和组装, "水温调节器 - 拆卸和安装"。 欲知更多资料，请咨询您的卡特彼勒代理商。
注: 如果只更换水温调节器，则排放冷却系统中的冷却液并使液位低于水温调节器壳体。
