![]() So, the new Ford orange is being phased-in after each engine family has been revisited and updated to accommodate the fluid. Anyway, that’s not a good idea where gaskets and seals are concerned most techs would agree that a gasket shouldn’t become softer than intended. That 2-EHA additive is also a “plasticizer” – it’s capable of making things soft or pliable, which is what the word plastic means in science. Meets the requirements of WSS-M97B44-D, GM 6277M and ASTM D 3306Ĭompatible with DEX-COOL® engine coolantsīut also, as you see, Ford is concerned that this specialty orange coolant not be used elsewhere. Do not use this product in systems originally equipped with any green-colored, conventional engine coolant such as Motorcraft® Premium Engine Coolant, meeting Ford Specification ESE-M97B44-A, or with the yellow-colored, longer-life Motorcraft® Premium Gold Engine Coolant, meeting Ford Specification WSS-M97B51-A1, or with the dark green-colored Motorcraft® Specialty Green Engine Coolant, meeting Ford Specification WSS-M97B55-A Provides year-round antifreeze, anti-boil and corrosion protectionĪ 50/50 mixture of coolant and distilled water provides freeze protection down to -34☏ (-37☌) and boiling protection up to 265☏ (129☌) Orange-colored, longer-life, ethylene glycol-based, engine coolant for use in gasoline and diesel engines. Specialty Orange Engine Coolant with Bittering Agent Moreover, Ford acknowledges this right in their Motorcraft parts catalog. Any product produced for GM and meeting the performance spec can be called by that name, and many chemical companies produce qualifying product. So has Ford gone all GM-ish on us? Mostly not, because most people forget that “Dex-Cool” is actually a specification, not a distinct product. The extra chemical is a salt form of the organic compound 2 –e thylhexanoic acid and you’ll find almost the exact mixture in a Dex-Cool product give or take a few minor variations. The MSDS for Ford’s Motorcraft coolant reveals that it is mostly ethylene glycol, with 2-5% 2-EHA (you may see that on the jug’s label) added. That’s why mixing coolants types (colors) isn’t recommended on most cars you may introduce a problem into a system that can’t handle it. ![]() They can provide longer service life, but, containing acid, they can also attack seals and gaskets not made to withstand them. OAT coolants pose a good news – bad news situation for a manufacturer. The industry in general, and GM in particular began to move to a new chemistry several years ago. The OAT designates the familiar term “organic acid technology” and refers to a product generally free of silicates, nitrates and borates in the chemistry. Here’s a look at the what and the why.įord refers to their recommended product as E-OAT, with the E representing the fact that the product is already in use in Europe. Some owners are concerned that their favorite car company has crossed over to “the dark side” and adopted General Motors Dex-Cool, a sure sign of an automotive apocalypse. The Ford owners’ and enthusiasts forums on the Internet are awash in questions and discussions of Ford Motor Company’s recently-announced gradual changeover to a standard coolant for all their engines.
