I worked with International during their cavitation crisis of the 6.9L and 7.3L IDI, helping to write bulletins, provide technical field data, and testing several different types of coolants, SCA's and mixtures thereof. To give you a little background, first let me say that I've had extensive training and education in the field of coolants, some by the coolant manufacturers themselves. I think Bob realizes that much of his information is out-dated, pertains to certain engines other than our Powerstrokes, and is just plain wrong. I've been getting lots of PM's about Bob's coolant/SCA article (the sticky that was closed), and I would like to address a few things to help folks better understand.

It Was mainly directed at a Post about the Evans Waterless Coolant.Īlso Some new members and powerstroke owners have no idea what antifreeze to pour into their cooling system, needless to say how to maintain it. Some might not find it interesting, but Oh Well. Summer is here and we all should have our Trucks Prepared. I just wanted to post this info on Coolant from my bud Gooch, on another Powerstroke Board. I went to test mine and it read fine.(strips not old) Regardless of make of coolant or elc or not, Shouldnt it have a proper amount of sca's and be able to be detected on the strips? It confuses me that international told him he needed no additive! There was no nitrate reading at all on the strips when i tested it. Now that I think of it just cause its not old school green its the newer stuff, we dont know if it even was the good international or the ford coolant thats in it. PS: also, he bought this truck with 65k on it. The 03 motor still has wet lined cylinders etc. He went to international to get the additive(he lives close to a place) They asked him what color antifreeze and then said theres no need for any additive.Īm I nuts? NO need for nitrates? I am sure he did not mention, we tested it and its out all depleted.Ĭant you test the elc coolant just like it was the green stuff? Just to make sure? AT least get the nitrate levels to where they are supposed to be and then change the coolant in a couple months or so. I told him its a good idea to flush it and replace, but if he cant, lets at least add 2 bottles of the dca-4 additive and retest it. Hes a bit short on cash flow or money to spend on the truck, since we just did some other work. The coolant is original and has 150k on it. However, i think its a good idea to still check.
I know with this coolant there is supposed to be no reason to check nitrate levels. Sorry that this displays with so much waste space - couldn't be compacted more, apparently du to forum formatting requirements.My co worker has an 03 7.3 truck. Perhaps a RAV4 owner who is a chemist could determine whether this is a correct or incorrect assumption. This technology provides superior protection to all components of the cooling system including those exotic materials like aluminum and magnesium found in the modern day engine."Īccording to the article Toyota coolant and Chevron Dex-Cool would appear to be based upon the same technology. OATs are Long Life Coolants (LLC), based on minimally depleting Carboxylate Technology. "OAT is an acronym for Organic Acid (Additive) Technology which describes the type of materials responsible for the corrosion protection offered by a coolant of this type. From an article by Reochem, Inc., Coolant Experts:

The Toyota RAV4 Owner's Manual says that coolant used should be either Toyota Super Long Life Coolant, or "Similar high quality ethylene glycol-based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology." Chevron Dex-Cool coolant employs the same labeling and uses the word "carboxylate" in its technical data description, rather than "organic acid," which Toyota uses.
