  • N-News article
  • In the Jan Feb Mar issue of N News, there is an article titled Keeping it Cool. It states that Prestone Antifreeze should not be use as it is an Organic Acid Technology (OAT) product and only Inorganic Additive Technology (IAT) should be used in my NAA. I have had the tractor for 2 years and have used Prestone twice. So Far, I haven't noticed any leaks, but would like to know what others use in their tractors and if I should flush and fill with another brand ASAP. Thanks.

  • FWIW
  • FWIW & FYI: Here's some info from the OEM NAA Owner's Manual:


    I'll add too that if you don't keep the fan belt tension tight, it may also cause overheating as the air flow to the radiator will be diminished. A loose fan belt will also cause loss of charging as well.

  • Read this article. I'm unfamiliar with what it meant but this should explain it I think. It is the orange and green. I've always used the green Prestone in my tractor and vehicles. Never a problem. Interesting article though. Green is IAT and Orange is OAT.

  • "Tabitha Njogu
    Tabitha graduated from Jomo Kenyatta University of Agriculture and Technology with a Bachelor’s Degree in Commerce, whereby she specialized in Finance"

    I note the lack of science or engineering degrees. Basically a "fluff" article with the only value being the warning against mixing the two types of antifreeze.

    I remember that there was a push to replace traditional antifreeze with a non-toxic version so pets and wildlife would not be poisoned by drinking it. Perhaps that is the real difference between the two types?

    What I do know is that orange antifreeze is Dexcool, developed by GM about 25 years ago. No product developed in the 1990's would be the "only" type that should be used in a 1939 to 1954 tractor!

  • Re: N-News article
  • I read several articles that basically said the same thing. Hers was the easiest to understand. The others had more ENGINEERING AND SCIENCE but were more complicated to understand. Yes the original was DExcool by GM. Lots of problems with it. I know several people who experienced problems with it. Green should be used in old tractors.

  • I always thought that Dexcool was pushed by GM so they could charge more for antifreeze.

    About that time there was a push to make antifreeze non-toxic, but that seems to have died out. Probably because non-toxic options are impractical in the real world.

  • ....then there is the 3rd or 4th type that is supposed to be compatible & can be mixed with any of the others.

  • Re: N-News article
  • For MANY years, Prestone antifreeze is all that we used. ...Never experienced any problems in cars, trucks, or tractors.

    Prestone has changed their formulations over the years.

    I can't comment on the article because I have not seen it. ...I do not have the knowledge to confirm or dispute the info in the article.
