dex-cool/g05/green?

[Johnny248]

Looking at the back of this Zerex bottle, and it says:

Toyota,Nissan,Honda,Mazda, and other Asian makes 1996 and Prior G-05, Newer than 1996 Dex-cool

Is this correct? The Nissan Green, and Blue and Honda Blue are all Dex-Cool??

 

[bullwinkle]

No-Valvoline/Zerex REALLY need to change that bottle-the newer Japanese makes are using proprietary antifreeze which CAN be replaced w/Zerex Asian Formula-the phosphate based Asian antifreezes are NOT compatible w/Dex or G-05.

 

[Johnny248]

I didn't think that was right. I know that the Nissan anti-freeze is phosphate/silicate free. And I *think* the Honda anti-freeze is the same way. I know they are both Blue for whatever that matters. I'd like to think they are similar, but who knows.

Long story short, according to this bottle, regular "Green Low-silicate" can only be used in:

GM -96
Chrysler -01
Ford Trucks -02
Ford Cars -03

and thats it. No older European or Asian cars. This charT sucks lol

Green or, to a maybe slightly lesser extent, G-05 could be used in most anything, older European or Japanese. The issue with using green in an older Euro is phosphates but just don't add realy hard water and it'd be fine. With older Asians the issue is silicates might shorten waterpump life, emphasis on the word might.

That coolant reference chart is old and before Zerex released AVF and maybe before Green were all low silicate. Around '88 Jpanese came out with their own formula with no silicates or borates. Then around '04 they came out with their own longlife HOAT formula. Zerex AVF can cover these 2 formulas.

So between Green, G-05, Dexcool (Peak Global) and AVF, you can basically cover most coolant applications close enough without having to get the proprietsry coolant from the dealers.

Peak Global is not a dexcool clone (because it doesn't have 2-EHA) and is actually a good coolant replacement for Asian vehicles. Zerex Asian vehicle formula is even closer to an OEM coolant replacement, but it's also much harder to find.

 

[ponderosaTX]

The Japanese P-OAT coolants feature phosphates (P stands for phosphates); the phosphates provide corrosion protection before the organic acids deposit a protective film. Nissan coolants have historically been P-OAT coolants manufactured by CCI, the dominant coolant technology company in Japan and the dominant coolant manufacturer in the US. As far as I can tell, CCI manufacturers nearly all of the Japanese OEM coolants distributed in the US, Peak branded coolants, Zerex branded coolants, Motorcraft branded coolants, and most private label coolants (including Walmart SuperTech); they all come in the same bottles. CCI bought the Dow Chemicals coolant business over a decade ago. (CCI US manufactures essentially all coolant formulas including some DexClone coolants; they are not discriminating in this regard.)

According to the MSDSs for Nissan coolants that I have inspected, Nissan coolants use CCI P-OAT technology. Zerex Asian Formula and Motorcraft Specialty Green (Mazda FL22 coolant developed by CCI) are the best aftermarket products for Japanese vehicles originally equipped with CCI P-OAT coolants.

+1 Not only are the bottles similar , as well as code #'s on the front label.

 

[mechanicx]

I'm not sure CCI is manufacturing Ashland's Zerex or Old World Industries' product line or Prestone's. Maybe but it doesn't really matter. G-05 and Zerex AVF are BASF patents and Zerex has the license to produce them. Prestone and Zerex have their own Dexcool and Dexclone patents. I'm not sure about Peak Global. Bottom line is they are their own formulas and their own patents and not CCI's. CCI probably does have all the patents and licenses for Japanese OE coolant, but that makes sense since none of them are supplied by the other companies.

 

[PeteTheFarmer]

If CCI is Ford OEM, it would be interesting to know if they have their own formula or are simply producing under license the BASF formula Zerex has rights to.

At one time, I think someone here linked that Honeywell was producing coolant for Toyota. The details of that would also be good to know.

 

[Dan55]

Peak Global Lifetime and Honda Type II have similar numbers on the front and back of the jug (MC06 and the zero has a slash). I also have a jug of Mazda long life green, code F04 again with a slash. and similar to Peak long life (Dexclone)with the same code.Supertech (Walmart)same code. Jugs are similar, my jug of Motorcraft G-05 is totally different

 

[PeteTheFarmer]

I think though that the SuperTech components label on the back is similar to Prestone Extended life, mentioning Ethylene Glycol, Diethylene Glycol, 2EHA and sodium neodecanoate. It's been a while since I saw it, however.

MC could it mean Manufacturers Code ?
