Coolant is getting to be confusing, best advice, as with all fluids, is check your owner’s manual. Except for dex-cool I would us ethylene glycol or the newer non toxic. GREEN Good old American ethylene glycol with silicates and phosphates, my choice.YELLOW GOLD Same as green in fact some say it has a green tint.ORANGE Dex-Cool, uses 2-EHA and sebacate as inhibitor, both are under question. Original equipment in some GM also made by Zerex, Prestone and Havoline. I would not use has had too many problems and GM is reimbursing for some repairs. GREEN Japanese a darker green and has no silicates. Has a short life span 2- 3 years. RED Toyota Same as the green be careful it looks a lot like Dex-cool. Again short life span.PINK Toyota Extended life Japanese coolants. Uses sebacate and phosphates but not 2-EHA. Seems to be trouble free.GREEN Honda same as the Toyota pink. PINK VW Organic acid type some do have 2-EHA and some don’t would not recommend using it there are several others that meet the VW specs. The American green is the preferred replacementYELLOW European Ford Mostly used in Europe but starting to see it in some Fords. Low silicates no phosphates. It is just starting to be seen in the US as G-05 in the aftermarkets.ORANGE Chrysler same as the yellow ford.BLUE Korean same as the yellow and orange. BROWN oopps you mixed 2 or more coolants or added to much sealer.Many techs are still recommending Dex-cool and as long as your cooling system stays completely full this is fine. With the low capacity of many of the newer systems this can be a problem. I recommend American green or the newer G-05. These 2 should cover all your needs. The most important items are to change it when necessary and if you switch types to remove all the old coolant. This is almost impossible. The exchange machines leave about 10% left so to do it yourself is difficult to say the least. The best method I have found is the air powered vacuum. I have tried to blow out the excess coolant but still feel there was some residue.
