اخي العزيز انا افهم الانجليزي ولكن اردت ان اقول لك
ان منتج ابرو الاحمر هو رادييتر كولانت وليس به انتي فريز
مكتوب علىيه ["not anti freeze " اي ليس انتي فرييز
ورقم المنتج ec-502 اذا حبيت تتاكد ....
وبا اتوكل على الله واخذ حق تويوتا ......
ولكن هل ينفع لسيارات هويونداي-النترا؟؟
لاني اعتقد انه مخصص لتويوتا وصناعتها وحديدها وكل مواصفاتها من حيث الحراره وغيرها تختلف عن هيونداي

Ethylene glycol base for aluminum radiator
أخي :
كلامك صحيح .
وأغلب المُبردآت الحديثة
بها { أثلين جلكول ethylene glycol } .
الأثلين مآدة كحولية من المنتجآت النفطية .
.
واللي أقدم منها بها مآدة { سلكيت Silicates }
بس السلكيت Silicate مآدة أكآلة
اللي هي خليط الأكسجين والسلكون .
Silicates are deemed to be abrasive in a cooling system, and are blamed for premature water pump seal failure.
With the average miles per year per car on the rise, it does seem to be a valid concern. But is it worth the price of a dex-cool clean up? If your water pump is timing belt driven, the water pump may be replaced at 60,000 or 90,000 miles anyway.

واللي تكون أورقآنك .
مثل حقت جي أم Dex-cool :
Organic Acid Technology or OAT's are coolants that are formulated without the use of silicates. Since silicates have a short life, removing them allows a longer service life. Typically, coolants advertised as 5 year, long life , extended life or Dex-cool are examples of OAT's. Common components to OAT coolants are Carboxylate, sebacate, and 2-ethylhexanoic acid (2-EHA), which are corrosion inhibitors, used instead of silicates. Depending on which manufacturer is filling the jug, the inhibitors may change. Dex-cool uses 2-EHA which among other things is a plasticizer which has the effect of softening plastic. GM intake manifolds are made of plastic........... If it is found that Dex-cool is dissolving the gasket material, it will validate what some folks have been saying for a long time: Dex-cool eats gaskets. We'll see. Prestone doesn't use 2-EHA in it's long life coolant, instead uses carboxylate.

Isn't all antifreeze compatible? Sorry, but it isn't. There are a few cases where you can get a fast case of corrosion, some where the water pump can be both eroded and corroded to an early death, and a lot of cases where you can shorten the effective life of the antifreeze. Antifreeze itself (most commonly a chemical called ethylene glycol) doesn't wear out–ever–but the key ingredients are the rust and corrosion inhibitors, and they get used up. The most common inhibitors, silicates for aluminum protection, are used up faster than others. That's why some new cars (all General Motors, Mercury Cougar, VW/Audi models) have red or orange antifreeze with a new class of inhibitors, called organic acids. Examples of U.S. brands with these organic acids: Havoline Dex-Cool and Prestone Extended Life, both recommended for five years or 150,000 miles. That's the good news.
