使用方法：

1、施工对象：

新车、磨合期后的车

2、施工操作流程：

（1）、车辆进入工位后打开暖风，对发动机进行常规检查：发动机水温、故障灯、暖风情况、冷却系统检漏。（如有渗漏维修后再操作）

（2）、拧开放水开关或拆开下水管，把原车冷却水放掉，拧紧放水开关或装好下水管。

（3）、等发动机降温后往水箱里加进清水，起动发动机让冷却系统进行清洗，清洗过程加油门让节温器打开（不开空调时风扇转动）

（4）、清洗完成后拧开放水开关把水放掉，拆开上、下水管，暖风管、中缸放水螺丝、副水箱（若螺丝太紧建议不拆），有双空调的车型，还需拆除后排暖风管。

（5）、等发动机降温后用清水清洗整个冷却系统一遍，如水箱、缸休、暖风箱、副水箱等。

（6）、用UD专业风枪把冷却系统的水吹干净。吹水流程：（1）吹干净水箱内的冷却水。（2）吹干净缸体内的的冷却水。（3）吹干净暖水箱内的冷却水（保证出水管无水珠则可）。

（7）往中缸加注500毫升优道除水剂，用风吹出来（用杯接住），用测水仪测含水量（须测3次以上）仪器刻度达53以上，再把缸休中的除水剂吹干净。

（8）、拧紧放水开关，装上上、下水管、暖风管、中缸放水螺丝（注：留一条位置高的管不装，加注无水冷却油时让它排空气），清洗吹干后装上副水箱。

（9）、往水箱里添加无水冷却油，添加过程用手指捏上下水管进行排空（如该车型有放空螺丝则拧开螺丝进行排空），当水箱里的冷却油加满时，起动发动机踩油门让节温器打开（加速到2500转/分，密切留意水温变化及管道状况）。

（10）、再往水箱及副水箱添加无水冷却油直到标准液面，拧上水箱盖道路试车，路试后打开水箱盖测无水冷却油中的水含量，仪器刻度达53以上，并检查无水冷却液的液面高度（不够时添加到标准液面）。

（11）、检查各水管有没漏水，冷却系统是否正常，在水箱盖和车尾贴上UD发动机环保冷却油警告标志，以免再次加入传统冷却液和水。

误区and注意事项！！！！

误区和注意事项一：用自来水或者不合标准的冷却液来替代无水冷却油，或是在有优道无水冷却油上混合自来水或者不合标准或是含水的冷却液来使用？ 一会影响本品的性能 ，二是会出现以下几种情况。

误区和注意事项二：行车时发现冷却液不够发动机温度偏高，这时车上没有UD冷却油，则可以添加一些纯净水先解燃眉之急，然后有条件时再把冷却液彻底更换成UD冷却油，恢复原车性能。

Product features:

1. Youdao water-free and environment-friendly cooling oil (coolant) adopts high-boiling point combined with high-efficient anti-foaming formula, and refers to the anti-corrosion technology of Germany national laboratory coolant, which is refined from advanced polyol, anti-oxygen agent, anti-cavitation agent and other additives.

2. High boiling point and low freezing point. (boiling point: 190 ℃ solidifying point: 60 ℃), not ice cold resistant, eliminate "boiled" worry, hot car can open the tank cover at any time.

3. No rust, no scale, no corrosion, no cavitation, no evaporation, no pressure. Extended the service life of engine parts, reduce maintenance and replacement.

4. Effectively improve and balance engine temperature, reduce engine wear and improve engine performance.

5. Shorten the time to reach the normal temperature when the engine starts up, reduce the noise of the engine and reduce the exhaust emissions.

6. Eliminate the phenomenon of "superheated vertex" on the top of cylinder, and prevent spontaneous combustion and explosion - proof shock. Increase torque, increase power and reduce fuel consumption.

7. High quality products, one time injection, durable, really no need to replace the cooling oil.

Usage:

1. Construction objects:

A new car, a car after a period of wear and tear

2. Construction operation process:

(1) after entering the station, the vehicle will turn on the warm air and carry out routine inspection of the engine: the temperature of the engine, the fault lights, the warm air and the leakage detection of the cooling system. (if there is leakage, it can be operated after maintenance)

(2) turn on the water switch or open the downpipe, release the cooling water from the original car, tighten the water discharge switch or install the downpipe.

(3) after the engine cools down, add water into the water tank, start the engine and allow the cooling system to be cleaned, and open the fuel valve during cleaning (the fan turns when the air conditioner is not switched on).

(4) after the cleaning, turn the open water switch to release the water, and open the upper and lower water pipes, the warm air pipes, the central cylinder drain screws, the auxiliary water tanks (if the screws are too tight, it is recommended not to remove).

(5) after the engine cools down, clean the entire cooling system with clean water, such as water tank, tank rest, warm air box and auxiliary water tank.

(6) blow the water out of the cooling system with the UD professional air gun. Blow water flow :(1) blow the cooling water in the clean water tank. (2) blow the cooling water inside the cylinder. (3) clean and warm the cooling water in the water tank (make sure there are no water drops in the outlet pipe).

(7) add 500ml of water remover to the middle cylinder, blow it out with the wind (catch it with the cup), measure the water content with the water meter (more than 3 times must be measured), and then blow the water remover out of the tank rest.

(8) tighten the water discharge switch, install the up and down pipes, warm air pipes, and water discharge screws in the middle cylinder (note: leave a high position pipe uninstalled, and let it drain air when adding water cooling oil), clean and dry it and install the auxiliary water tank.

(9), to add without water cooling oil in the tank, adding process with fingers up and down the pipe emptying (such as the model has a vent screw is unscrewed the screw for emptying), when the cooling oil in the tank filled with starting the engine thermostat open on the accelerator (up to 2500 RPM, closely monitor water temperature change and the status of the pipe).

(10) add water-free but oil-free oil to the water tank and the auxiliary water tank to the standard liquid level, screw on the road test of the water tank cover, open the water tank cover after the road test to measure the water content in the water-free but oil-free water cooling oil.

(11) check whether the water pipes are leaking and whether the cooling system is normal. Affix the warning mark of UD engine environmental cooling oil on the cover of the water tank and the rear of the car, so as not to add the traditional cooling fluid and water again.

Error and attention!!!

Myth and cautions 1: use tap water or substandard coolant instead of water-free oil, or mix tap water with water-free oil or non-standard or water-containing coolant in a preferred channel? It will affect the performance of this product for a while.

Mistake area and notice item 2: when driving, discover coolant is insufficient engine temperature is on the high side, do not have UD coolant oil on the car at this time, can add a few pure water to solve urgent need first, when have the condition, change coolant thoroughly into UD coolant oil, restore original car performance.
