G3500 Engines Caterpillar

Engine Coolant Temperature (Low)

Usage:

G3508 2TJ

可能的起因

水套水加热器有故障
水温调节器有故障

推荐的修理

检查水套水加热器

确定有故障的水套水加热器工作是否正常。

如果水套水加热器工作不正常，确定加热器故障的原因。进行必要的修理。

检查水温调节器

直到水套水达到调节器打开温度时，水温调节器才应开始打开。待发动机冷却之后再起动发动机。检查水套水出口的软管。如果软管是热的，而正常工作温度还没达到，调节器可能卡在打开位置。

如果水温调节器有故障，按照系统操作/测试和调整, "测试冷却系统"来检查水温调节器。必要时，更换水温调节器。
