Ce tip de antigel ?

[trutzydany]

@bau : merci frumos pentru raspunsul tau !!!

Se spune ca nu este bine sa se amestece cu un antigel ce are o compozitie mai mare de silicati .(dar nu e o crima )
Daca se schimba antigelul cu Aral antifreeze Silicatfrei trebuie sa se schimbe tot ,nu ar fi indicata completarea...

De ce nu e indicata completarea cu un antigel o idee mai pur?
Ce componente va afecta in instalatia de racire dpdv mecanic?

Din brosuri ambele sunt etilen glicol, doar Silicatfrei e mai pur cu 3-5% decat Extra.

@SeKAh
Am spus ca nu este chiar o nenorocire amestecul .
Nu are chiar aceeasi compozitie .
Cel Silikatfrei mai are niste inhibitori de coroziune in plus si niste acizi organici (ce nu prea se pupa cu silicatii )
La amestec se creaza precipitati de silice (impropriu spus nisip ) ce se depun prin canalizatiile fine blocind uneori circulatia lichidului sau pompei de apa .(SE PARE ca poate distruge garniturile siliconice si presetupa pompei de apa,SE PARE ca nu este indicat la motoare Diesel )
Mi-a placut chimia ,am un fel de specializare in chimie dar nu in chimia silicatilor ,de aceea nu ma consider un specialist in acest domeniu .(Poate avem un coleg sa ne lamureasca mai bine )

O sa incerc sa copiez un mic articolas pe aceeasi tema ,din pacate nu este tradus dar este inteligibil.

Most antifreeze products sold for the past several years have been the traditional "green" coolant. This type is good for two to three years and up to 30,000 miles. The green antifreeze contains silicates, phosphates and/or borates as corrosion inhibitors to keep the solution alkaline. Green
antifreeze should be changed every two years or so.

"Orange" antifreeze is a long life or extended life type of antifreeze. The difference between the two colors is that orange antifreeze contains a different type of corrosion inhibitor. Orange antifreeze contains organic acids that protect engine parts from corrosion. Silicate (green) type antifreeze does not mix with orange type antifreeze. Never mix the two colors in a cooling system. Orange type antifreezes are good for five years or 100,000/150,000 miles in newer vehicles (1996 and later.Toyota uses a red antifreeze in many of its products and should not be confused with the orange type long life antifreezes. It is essentially the green type of antifreeze that contains red dye to give it the red color.

There are many types of engine coolant, colors range from the old standard green to the new blue coolant. Some of the main differences between the green coolant and the newer mixes is the chemicals made to create the coolant. The new Red, Blue and Yellow coolants are more environmentally friendly and designed to last longer between services. You should not mix the different coolant types, if your engine came with red coolant then you should add red coolant only.

Today, antifreeze/coolants come in many colors and each signifies a purpose. It can be confusing to have special-needs coolants that can be identified by their color when the color is not an industry standard.

For the past several years, vehicle manufacturers have introduced a variety of new extended-life coolants. Each seems to have its own colors. Each formula considers corrosion protection, service life and chemical compatibility. We have green coolants, red coolants, blue coolants, yellow coolants, even pink coolants. The closer we look at this diversity, the more confusing it becomes.

Anti freeze liquid RED or BLUE ??
Think you could find the red will be 5 year and the blue 2-3 year life.
It shouldn't matter too much which you uses as long as you flush out the system. As stated above the Red stuff lasts for 5 years the blue/Green lasts for 2-3 years. Both are a type of Glycol base but the red uses organic acid technology to last longer. Obviously the red stuff is more expensive to buy though. Its up to you which you choose, and might depend on how long you are going to keep the car.

In fisele celor doua produse (data sheet) de pe website Aral scrie altceva.

PS: Am citit si textul in engleza care spune ca nu se amesteca cele doua componente doar pentru ca cel portocaliu dureaza mai mult. Asta e singurul argument.

Imi recomanda cineva un antigel bun in afara de ARAL Antigel Antifreeze Extra, care se pare ca se gaseste mai greu?

Eu în Sportage am de culoarea verde. Până acum, 3000 km, nu a trebuit să completez. Acest antigel după părerea voastră este compatibil cu cel existent? Am mers pe culoare și recomandarile din specificații :

Am tot cautat si eu antigel acum ceva timp si am ajuns la acelasi produs ca @ciklon insa nu l-am schimbat deocamdata. L-a schimbat cineva? Pare ok ca specificatii.

[Caralumba]

<<ciklon>> si <<ionutp>>, fara suparare dar, daca vorbiti de Sportage pe arie de Ceed I, n-o sa mai gaseasca nimeni in veci informatia corecta.
