The thing had about 4 years of wear and tear and 110K miles. I changed my 2011 antifreeze when I did the timing belt. So you guys just be very careful what you put into these beautiful vehicles. Here's an example GM has for years used the orange coolant which is totally incompatible with the 'Prestone-type' green coolant. The different colors are not for fun - they are to help make coolant selection fool-proof. Plus, there is no financial benefit to not use the correct coolant - the stuff pretty much all costs about the same. Different coolants can be completely different types which are not compatible. ![]() You can exercise your intelligence and search aptitude and think you have outsmarted the engineers who spec'd the coolant but you haven't. This is the only way to maintain and extend the long-term coolant protection found in today's cars. When adding coolant or doing a change, it is best to use the exact same type that came in the vehicle and to use distilled water to make the correct mix or use the pre-mixed containers. You can get away with using non-distilled water if you're willing to change coolant annually. The 'slugging', or precipitation of silicates in coolant, usually derives from mixing different types of coolant and/or using non-distilled water for diluting. Beans, meat and tomato something and the rest of the chili is usually different depending on the Cook… The main result after an hour or two (with most home made chili’s), you will find yourself crapping your brains out later on the toilet… My concern would be the first three ingredients and that the antifreeze's meet both ASTM D-3306 and D-4340 testing.Īs for the other chemicals, it reminds me of those that make their own Chili… Yes, Chili… There are basic ingredients i.e. One more thing: I’ve noticed that there are three basic ingredients to most of these antifreeze's, Water, Ethylene Glycol and Diethylene… After that they tend to go in different directions. Plus as you should know, the older antifreeze DID HAVE ALCOHOL in it and I could see that having a problem in Aluminum engines… The newer engines (starting years ago) and parts are all most all aluminum and they had to change the chemical make up of the antifreeze's years ago to stop the deterioration of the metals in the coolant chain… ![]() I remember reading somewhere that a person had a Toyota and they put in a after market antifreeze and later they had slugging problems or something like that but never mentioned what antifreeze solution nor the ingredients in the antifreeze. I’ve since bought Peak that did have the requirements of both ASTM D-3306 and D-4340… I check my Prestone and it had ASTM D-3306 and ASTM D4985 but no ASTM D-4340 so I decided not to use Prestone. Going by the information on the pictures I’ve put up here…What I did was look for antifreeze having the testing requirements of ASTM D-3306 and ASTM D-4340 as well as having at least Ethylene-glycol in it too… ![]() Kind of like in the past when Sonoco would have Yellow gas, Esso (Exxon) has red gas and so on…ĪSTM D-4340: Standard Test Method for Corrosion of Cast Aluminum Alloys in Engine Coolants Under Heat-Rejecting Conditions.ĪSTM D-3306: Standard Specification for Glycol Base Engine Coolant for Automobile and Light-Duty ServiceĪSTM D-4985: Standard Specification for Low Silicate Ethylene Glycol Base Engine Coolant for Heavy Duty Engines Requiring a Pre-Charge of Supplemental Coolant Additive (SCA) It doesn’t seem that the color of one’s antifreeze means anything other than a useless additive for coloring. I’ve noticed that both Toyota and Honda antifreezes meet a certain ASTM (American Society of the International Association for Testing and Materials) ASTM code. I’m just guessing here but maybe most are looking at the wrong information when trying to find out if one can use a third party antifreeze. To start, I own the Odyssey 2012 and Lexus 1998.
