PM825 3C6

------ 警告! ------

在引擎工作溫度下,引擎冷卻液是熱的且具有壓力。

蒸氣會造成人員受傷。

只在引擎停機後,且加注口蓋已降溫到可徒手拆下後,才能檢查冷卻液液面。

慢慢地拆下加注蓋以釋放壓力。

冷卻系統內的防鏽劑中含有鹼性物質。 避免與皮膚及眼睛接觸,以免受傷。


定期更換水溫調節器以減少意外停機時間和冷卻系統故障。

更換水溫調節器前,應該先清潔冷卻系統。 請在冷卻系統完全排清的同時,更換水溫調節器。 冷卻系統的冷卻液排放至低於水溫調節器外殼時,請更換水溫調節器。

附註 如果您只要更換水溫調節器,冷卻系統冷卻液應排放至低於水溫調節器外殼的位置。


注意事項

若未定期更換引擎節溫器,可能會造成引擎嚴重損壞。


  1. 打開右側引擎檢修門。


    插圖 1g03432448

  2. 卸下固定調節器外殼的螺栓 (1)。 鬆開軟管夾 (2)。

  3. 取下調節器外殼 (3)。 從外殼 (3) 取下所有用過的墊圈。


    注意事項

    Caterpillar 引擎中包括有分流設計冷卻系統,必須安裝恆溫器才能操作引擎。

    如果恆溫器的安裝不正確,將會造成引擎過熱。 組裝前請檢查墊圈,如果有磨損或損壞請加以更換。


  4. 將新墊圈安裝到調節器外殼上。 安裝新的水溫調節器。

  5. 裝上螺栓和蓋子。

  6. 鎖緊軟管固定夾。

  7. 向冷卻系統加注冷卻液。

  8. 關閉右側引擎檢修門。
