放熱不良の故障（修理？）
First, engine and air-conditioning system radiation bad 1.
when traffics jams or the long time idling regime revolution,
the engine noise increases,
turns on time the air conditioning is most obvious;
2. the idling regime is not steady,
the anxious acceleration is incapable,
the engine has the different sound. 3. hot vehicle flameout several minutes later,
the vehicles are not easy to start. The hot vehicle goes when can sometimes the automatic flameout;
4. the refrigerated car space and time adjusts the refrigeration temperature to be very low, the hot vehicle hour air conditioning refrigeration effect is not good.
Moreover in the air-conditioning system has the big resonating buzz whining noise; 5. when hot vehicle idling regime,
the air conditioning compressor coupling attracts breaks frequently,
even separates, causes the hot vehicle air conditioning not to refrigerate. Second,
breakdown solution 1. uses between the compressed gas clean condenser and water tank's dust;
2. the hot vehicle hour,
in the water tank down-flow pipe's temperature difference cannot be too big,
otherwise must inspect the thermostat the opening and the water pump whether to have loses the extension the breakdown; 3. after hot vehicle,
inspection anti-icing fluid Chu watering can upper extreme return pipe backwater situation,
if the backwater impeded or the jamming can cause the water temperature to be excessively high,
Jieda vehicle this breakdown are excessively many;
4. because the anti-icing fluid increase and the replacement are not standard,
will create the engine canal and the water tank stops up ahead of time,
presents the water temperature high phenomenon.
The anti-icing fluid two years replace one time, when replace and the increase must use the original factory fitting.
Please note:
After the engine cooling system joins the water,
or joins the anti-icing fluid density has surpassed above 60%,
can create the water temperature excessively high phenomenon.
一、发动机和空调系统散热不良
1.堵车或长时间怠速?畚转时，发动机噪音增大，开空调时最为明显；
2.怠速不稳，急加速无力，发动机有?尺?技。
3.热车熄火十几分钟后，车辆不易?企动。热车行驶时有时会自动熄火；
4.冷车时空调制冷温度很低，热车时空调制冷效果不好。而且空调系统内有较大的共振嗡鸣声；
5.热车怠速时，空调压缩机?偕合器吸断频繁，甚至断开，造成热车空调不制冷。
二、故障的解决方法
1.用高压气体清洁冷凝器与水箱之间的灰尘；
2.热车时，水箱上下水管的温差不能太大，否则需检查节温器的开度和水泵是否有丢转的故障；
3.热车后，检查防冻液储水罐上端的回水管回水情况，若回水不畅或堵塞会造成水温过高，捷?甼车此故障过多；
4.由于防冻液的添加和更换不规范，会造成发动机水道和水箱提前堵塞，出现水温高的现象。防冻液?姶年更换一次，在更换和添加时必须使用原厂配件。请注意：发动机冷却系统内加入水后，或者加入的防冻液的浓度超过了60%以上，都会造成水温过高的现象。
