產品特點：

1、優道無水環保冷卻油（冷卻液）采用高沸點結合高效的抗泡配方，并參考德國國家實驗室冷卻劑抗腐技術，由高級多元醇，抗氧劑，防氣蝕劑等多種添加劑精制而成，

2、沸點高、冰點低。(沸點：190℃  凝點：-60℃)，不結冰耐嚴寒，徹底消除“開鍋”煩惱，熱車可隨時打開水箱蓋。

3、無鐵銹、無水垢、無腐蝕、無氣蝕、無蒸發、無壓力。延長了發動機部件的使用壽命，減少維修和更換。

4、有效改善和平衡發動機的溫度，減少發動機的磨損，提升發動機性能。

5、縮短發動機啟動時升至正常溫度的時間，降低發動機噪音，減少廢氣排放。

6、消除汽缸頂部“過熱頂點”現象，防自燃、防爆震。增加扭矩，增強動力、降低油耗。

7、高品質產品，一次加注，經久耐用，真正無需更換的冷卻油。

使用方法：

1、施工對象：

新車、磨合期后的車

2、施工操作流程：

（1）、車輛進入工位后打開暖風，對發動機進行常規檢查：發動機水溫、故障燈、暖風情況、冷卻系統檢漏。（如有滲漏維修后再操作）

（2）、擰開放水開關或拆開下水管，把原車冷卻水放掉，擰緊放水開關或裝好下水管。

（3）、等發動機降溫后往水箱里加進清水，起動發動機讓冷卻系統進行清洗，清洗過程加油門讓節溫器打開（不開空調時風扇轉動）

（4）、清洗完成后擰開放水開關把水放掉，拆開上、下水管，暖風管、中缸放水螺絲、副水箱（若螺絲太緊建議不拆），有雙空調的車型，還需拆除后排暖風管。

（5）、等發動機降溫后用清水清洗整個冷卻系統一遍，如水箱、缸休、暖風箱、副水箱等。

（6）、用UD專業風槍把冷卻系統的水吹干凈。吹水流程：（1）吹干凈水箱內的冷卻水。（2）吹干凈缸體內的的冷卻水。（3）吹干凈暖水箱內的冷卻水（保證出水管無水珠則可）。

（7）往中缸加注500毫升優道除水劑，用風吹出來（用杯接住），用測水儀測含水量（須測3次以上）儀器刻度達53以上，再把缸休中的除水劑吹干凈。

（8）、擰緊放水開關，裝上上、下水管、暖風管、中缸放水螺絲（注：留一條位置高的管不裝，加注無水冷卻油時讓它排空氣），清洗吹干后裝上副水箱。

（9）、往水箱里添加無水冷卻油，添加過程用手指捏上下水管進行排空（如該車型有放空螺絲則擰開螺絲進行排空），當水箱里的冷卻油加滿時，起動發動機踩油門讓節溫器打開（加速到2500轉/分，密切留意水溫變化及管道狀況）。

（10）、再往水箱及副水箱添加無水冷卻油直到標準液面，擰上水箱蓋道路試車，路試后打開水箱蓋測無水冷卻油中的水含量，儀器刻度達53以上，并檢查無水冷卻液的液面高度（不夠時添加到標準液面）。

（11）、檢查各水管有沒漏水，冷卻系統是否正常，在水箱蓋和車尾貼上UD發動機環保冷卻油警告標志，以免再次加入傳統冷卻液和水。

誤區and注意事項！！！！

誤區和注意事項一：用自來水或者不合標準的冷卻液來替代無水冷卻油，或是在有優道無水冷卻油上混合自來水或者不合標準或是含水的冷卻液來使用？ 一會影響本品的性能 ，二是會出現以下幾種情況。

誤區和注意事項二：行車時發現冷卻液不夠發動機溫度偏高，這時車上沒有UD冷卻油，則可以添加一些純凈水先解燃眉之急，然后有條件時再把冷卻液徹底更換成UD冷卻油，恢復原車性能。

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.
