1. After the hot car, check the return water condition of the return pipe at the upper end of the antifreeze water storage tank. If the return water is not smooth or blocked, the water temperature will be too high.

溫馨提醒：在維修中不要盲目拆件和換件。

Warm reminder: don't dismantle and replace parts blindly in maintenance.

2、檢查冷凝器與水箱之間的灰塵是否過多，用高壓氣徹底清洗，保證水箱和冷凝器有良好的散熱性能。

2. Check whether there is too much dust between the condenser and the water tank, and thoroughly clean it with high-pressure air to ensure that the water tank and the condenser have good heat dissipation performance.

溫馨提醒：平時注意擦拭冷凝器與水箱之間的灰塵。

Warm reminder: usually pay attention to wipe the dust between the condenser and the water tank.

3、在熱車時，檢查水箱上下水管的溫差，如果溫差太大，需要檢查節(jié)溫器的開度和水泵是否有轉(zhuǎn)速丟轉(zhuǎn)的故障。

3. When the car is hot, check the temperature difference between the upper and lower water pipes of the water tank. If the temperature difference is too large, it is necessary to check the opening of the thermostat and whether the water pump has speed loss.

溫馨提醒：水箱上下水管的溫差不能太大。

Warm reminder: the temperature difference between the upper and lower water pipes of the water tank should not be too large.

4、由于防凍液的添加和更換不規(guī)范，會造成發(fā)動機(jī)水道和水箱提前堵塞，出現(xiàn)水溫高的現(xiàn)象。防凍液兩年更換一次，在更換和添加時必須使用原廠配件。

4. Due to the non-standard addition and replacement of antifreeze, the engine water channel and water tank will be blocked in advance, resulting in high water temperature. Antifreeze should be replaced every two years. Original accessories must be used when replacing and adding antifreeze.

溫馨提醒：發(fā)動機(jī)冷卻系統(tǒng)內(nèi)加入水后，或者加入的防凍液的濃度超過了60%以上，都會造成水溫過高。

Warm reminder: when water is added into the engine cooling system, or the concentration of antifreeze is more than 60%, the water temperature will be too high.

5、空調(diào)系統(tǒng)中高壓端高壓力過高;空調(diào)制冷劑或空調(diào)制冷潤滑油加注過多;內(nèi)部自調(diào)試空調(diào)壓縮機(jī)的自調(diào)功能失靈，造成高壓過高;還有空調(diào)冷凝器的堵塞，以上故障都會加大發(fā)動機(jī)的負(fù)荷，消耗冷卻系統(tǒng)的散熱性能，導(dǎo)制水溫過高的故障發(fā)生。

5. In the air-conditioning system, the high pressure at the high-pressure end is too high; the air-conditioning refrigerant or the air-conditioning refrigeration lubricating oil is filled too much; the self-adjusting function of the internal self-adjusting air-conditioning compressor fails, resulting in the high pressure; and the air-conditioning condenser is blocked, which will increase the load of the engine, consume the cooling performance of the cooling system, and cause the high water temperature fault.
