配備有目測錶的引擎

(1) 加注口蓋
(2) 目測錶

如果引擎裝有目測錶,應觀察冷卻液在目測錶的位置。 在正常工作溫度下,正確的冷卻液液位在目測錶的上半部分。 如果冷卻液液位過低,應加入正確的冷卻混合液。

沒配備目測錶的引擎

------ 警告! ------

加壓系統: 高溫冷卻液會導致人員嚴重燙傷。 欲打開冷卻系統的加注口蓋,請停止引擎並等候冷卻系統的組件變冷。 緩慢鬆開冷卻系統壓蓋以釋放壓力。


在引擎關機並冷卻後檢查冷卻液液位。 只能在引擎已經關機而且冷卻系統加注口蓋冷卻到足以用手觸摸時,才能檢查冷卻液液位。

緩慢拆卸冷卻系統加注口蓋,以釋放其中壓力。 若未裝目測錶,則將冷卻液保持在注水管底部以下 13 mm (0.5 inch) 內。

添加冷卻液

附註如需正確冷卻液混合方法的資訊,請參閱此操作與保養手冊, "再注滿容量和建議"
(保養篇)。

  1. 將引擎熄火。 讓引擎冷卻。

  2. 緩慢拆卸冷卻系統加注口蓋,以釋放其中壓力。 加注適當的冷卻液混合物至水箱中。

  3. 清潔冷卻系統加注口蓋。 檢查冷卻系統加注口蓋的墊圈。 如果墊圈已損壞,應以新口蓋更換冷卻系統的舊加注口蓋。 安裝冷卻系統加油口蓋。

  4. 起動引擎。 檢查冷卻系統是否洩漏。
