![]() The normal OAT antifreeze service life is 5 years or ![]() It is recommended that OAT not be mixed with any Green, pink and blue have been added to the list Its first dye colors were orange and red. OAT can be either EG or PG but is mostly EGīased. ![]() OAT antifreeze had been widely used in Europe before its Organic Acid Technology (OAT) was the first LLC / ELC introduced in NorthĪmerica in 1994. The normal IAT service life is two years or 30,000 An IAT can be used with either ethylene glycol Inorganic Acid Technology (IAT) is the chemical composition for the traditionalĪntifreezes that are green in color. System's ability to perform its designed function of removing heat from criticalĮngine parts and to enhance the service life of the various cooling system Although straight antifreeze actually freezes andīoils quicker than tap water, when mixed with water in the proper proportions (aĥ0% / 50% mix is ideal) in a cooling system, it greatly increases the cooling Such as sodium silicate to protect aluminum from corrosion, anti-foaming agentsĪnd other corrosion inhibitors. It is also used as a carrier for different types of additives This issue is not static and new technologies and dye colors will continue to beĪntifreeze is used in cooling systems to both lower the freeze point of water and The member companies of the FMC are confident Which technology based on the information that is readily available at the time The purpose of this bulletin is to describe the dye colors currently available, theĬhemical technologies being used and which vehicle manufacturers are using Virtually no limit to the different dye colors that may be used. Orange and red dyes were used first now it appears there may be To accomplish this, they introduced different colored dyes for their LLC / ELC Manufacturers wanted to differentiate this new product from existing antifreezes. With the introduction of this totally new concept, antifreeze ![]() Then, long life (LLC) / extended life (ELC) coolant / antifreeze was introduced inĪn effort to reduce maintenance costs, downtime and environmental disposalĬosts and issues. Interval is normally about every two years or 30,000 miles (50,000 km) of use. Until recently, the color of the most commonly used antifreezes for both light dutyĪnd heavy-duty engine cooling systems was predominately green. I cant remember the name brand of the antifreeze but once I get up and about today ill check it out and let you guys know. On the back of the bottle it states that its for 2002 and up Chrysler/Jeep's. Out of the 4 auto part stores in my area, only one actually carries HOAT type antifreeze. The guy at the dealer pointed me in the right direction to where I could get this antifreeze and not have to pay out the butt at the dealer. Even if the bottle says compatible with all other antifreezes. So I talked to the Jeep dealer to find out more info about this antifreeze and they said the owners manual is correct and that you cant mix this HOAT type antifreeze with other types. I knew the fluid wasnt the original green fluid used in other vehicles I previously owned so I check out the owners manual and it states that you can only use HOAT type antifreeze which you buy directly from the dealer. Well enough to need to add more I guess you can say. Well in order for me to get the fan shroud/electric fan out I had to disconnect the upper radiator hose and lost quite a bit of fluid. My engine had been running a little hotter then normal due to all the dirt being clogged in the radiator from the huge water holes we decided to drive through. A few months after our first trip to Rausch Creek I decided to take out the fan shroud/electric fan so that I could clean the radiator really well.
