On an older thread I asked about a recommended coolant. A few people chimed in and recommended G-05 for both my Dodge and Nissan. However, I found a chart that says G-05 is not for asian cars. About half way down the page are two charts you can click on to view different coolants. Just wondering if this data is outdated or something? Here is the link....

They're being overly conservative and lumping a lot of different makes and model years under one category - "Asian". There are a lot of model years of Asian cars that will run fine on pretty much anything.

My wife's Altima had green coolant when we bought it used from the local Toyota/Nissan dealer.

It's not "misinfo", the Zerex chart is the same in not recommending G-05 for newer Asian's. G-05 is not the OE factory fill on Asian vehicles. Nor is G-05 recommended by the manufacturers for them. G-05 has silicates which the Asians manufacturers don't recommend, nor do the OE proprietaries contain.

That said, if you feel confident using it, with a complete flush and reasonable interval, then that's your choice. It is relatively easy to find in full strength at a reasonable price. If you choose not to use one of the silicate free universals or pricey OEM's, G-05 is something you could consider.

FYI, Nissan proprietary coolant (recent price quoted here $31) is 'green' in color, but not the same as traditional green. Like the other OE Asian coolants it is silicate free. Traditional green has some silicates. They are the same color though, which is why color is not a great indicator of coolant type.

That chart is not correct. Napa is really just recommending what they carry and want to sell. Zerex does recommend G-05 for '95 and earlier Japanese cars. And Zerex does recommend Dexcool for 96 and newer Asian cars. Dexcool along with 2EHA and silicates are not recommended by the Asian manufactures. Neither Dexcool or G-05 is OE recommended so it makes no sense to say G-05 can't be used but Dexcool can. But either could be used in an Asian vehicle. Dexcool probably has more potential for gasket incompability and to sludge, so I considered the silicates in G-05 that may theoretically shorten water pump life a lesser of two evils.

I'm not sure why Zerex recommends G-05 only through '95 since as far as I know the newer extended life coolant didn't start showing up in asians till about'03 or so. Probably Peak Global would be better than Dexcool for '96 up or '03 up asian vehicles.
 
Just a point of clarification about the NAPA chart not being "misinfo". From the stand point that G-05 it not recommended for any modern/recent Asian vehicles, that is accurate and also holds true for the Zerex chart also.

As for Napa's recommendation, it's Napa's recommendation based on the coolants they carry. Just as Zerex's recommendation of true GM based Dexcool, not the unversals like Napa, was based on what Zerex carried at the time. Now however, Zerex supposedly markets a premixed Asian formula which is supposed take the place of their original recommendation, (based on what they sold) that being GM based Dex-cool. So when looked at from that standpoint both Napa's and Zerex's charts could be considered "misinfo", when applied to modern/recent Asian vehicles.

Bottom line, no modern Asian, recommends G-05 or uses it as factory fill. The same holds true for true GM specd Dex-cool, the one that says Dex-cool on the jug.
 
Asian mfg's don't like silicates. Especially Honda, because they claim reduced water pump seal life.

Interestingly, on Zerex's data sheets, the silicate levels of the "Original Green" is 250ppm max, while the GO-5 runs 252-308, 290ppm typical.

Since I run the excellent POAT Honda Type 2 coolant in all my motorcycles, I think next time the Mazda/Ford Tribute is due, I might convert that to the Type 2 as well.
 
True, all the Asians recommend a silicate free formula. All of the universals are silicate free, some have 2eha, and some like the Napa chart recommendation of Peak Global Life do not. Hard to find though, in full strength.

Honda Type 2 is good, but it generally sold as a premix. Bernardi auto parts sells a very pricey full strength that comes in qts. only and is ~$26 a gal., before shipping charges.
 
When pricing information and it becomes available, that will tell more. Thus far all of the proprietary Asian's have been and continue to be expensive.

Inexpensive Asian proprietary has been an oxymoron. Maybe Ford will break the trend when it becomes available.
 
G-05 is not officially a recommended coolant for most Asian vehicles because it does contain a (very low) percentage of silicates. That said, the terror over silicates is pure idiocy. The whole planet used silicated coolants for decades, and at much higher concentrations than current silicated coolants, let alone a very low silicate mix like G-05. Waterpumps didn't spontaneously shred their seals. Would I run an old high-silicate coolant for 5 years? NO, that's when silicate precipitation happens and can damage waterpumps. But G-05 is a factory-fill coolant that is used in 5 year/50k mile applications all the time by Ford, Chrysler, Mercedes, and many others. Its perfectly safe for asian cars, and IMO the small percentage of silicates greatly increases aluminum protection. I would CERTAINLY prefer it to a dexclone like Prestone all-makes all-models.
 
+1. Also G-05's OAT is benzoate which seems to be a less aggressive inhibitor, and was used in the older Asian formula and original Green and no one found it to be a gasket eater. G-05 also has equal or greater service life as the Asian extended life. G-05 is also probably more compatible with hard water than Asian formula and about equal to Dexclone.
 
The terror over silicates may be pure idiocy just as the scare over any coolant with 2eha may be overly alarmist.

It now seems quite possible that Ford is moving away from silicated G-05 to a non silicated formula, similar to the Asian coolants. I'm sure they have their reasons, but it must center around silicates. It will be worth watching. And the engine composition of today is not the same as decades ago.

I'm just not sure that G-05 is any better than the universals in general, and Peak Global Life (which was the Napa chart rec) in particular, in Asian vehicles with regular 2-3 year maintenance.
 
I don't want to sound like a broken record, and I do think Dexcool (with the exception of PGL all "universals" are Dexcool no question about it) seems to work OK in late model Asian vehicles.

But silicated Green has been used in everything successfully. The dexclone problem with gasket incompatibility and sludging is by far more documented than silicates harming water pumps or anything else.

Ford has never ever stated anything negative about silicates that I have ever seen. Just the opposite they seem to like silicates just fine. If Ford is in fact going away from silicates it's probably for various other reasons besides having reservations, one of which might be a longer life on the FF.

The Europeans seem to still like the silicates. Bottom line is even if Ford is moving toward Asian formula they aren't backspecing it so far. That's the important thing here because I think Dexcool, Asian formula or whatever is fine in a FF late model.
 
G-05 should be totally fine for a 22RE and is probablythe best choice besides the OE coolant. Lots of them were serviced with silicated Green and it didn't seem to shorten water pump life or cause any problems. Also G-05 has about the same OAT inhibitor, benzoate, as the OE fill.

It's best to flush all the old coolant out before switching so you'll have a full charge of one inhibitor pack. You could always get the Toyota red long-life if you want the exact same formula.
 
Cool, thanks for the help Mechanicx. Would the Zerex Asian formula be a waste of money since you can only get it premixed?
