Just never mix with another type that happens to be colored green. So, running Walmart green, if it is an HOAT, might be fine. Toyota says their pink and red can be mixed, but it would be smart not to. So, never just assume a coolant the same color will be "ok" to top up with. The #1 rule with coolants is you never mix them (extremely bad sludging can occur if they are incompatible). Silicate and Phosphate free, and it can go 10 years between changes.īecause there is no standard for color, it is entirely possible that a green one will actually be HOAT or OAT, but read the label carefully first. Toyota Pink Super Long Life = Organic (OAT) meant for all aluminum everything. I recently tore down a Gen3 V6 that had run old fashioned IAT green all its life, the water passages were partially filled with sand (silicate that had condensed out of solution). Silicate free, so it can go 5 years between changes. Toyota Red Long Life = Hybrid Organic (HOAT) meant for iron block, aluminum heads and radiator. Original phosphate + silicate green = Inorganic (IAT) meant for iron block, heads and copper/brass radiator. Unfortunately, coolant makers don't have any standard so the color could mean anything. " Prove to me how it's "better"." - the concern is what's in the green? If the coolant turns brown, I would do another flush with Toyota Red just in case, but I'd leave it alone for now otherwise. It could potentially cause sludging in the cooling system, but a lot of people incorrectly mix coolants and I rarely hear of clogged cooling systems. You are technically not supposed to mix coolants, but I think you're OK. It works, but if you're doing the flush anyway, get the right stuff that will protect the cooling system better. The chemical mixture of the green is slightly different than the Toyota Red formula, though, so it's "not as good" at protecting the cooling system. There are many types of green coolants, but the "all makes and models" Prestone green coolant (which is what I used) is generally compatible with our cars in terms of chemical mixture, so it's fine. I suppose this would apply for someone who had leftover Red sitting in their garage and bought a new car. It'd be silly to do that, though, since the Pink supposedly lasts longer. You CAN, however, use Toyota Red on a newer Toyota. I forget the name of the metal every time, but you're not supposed to use Toyota Pink in a car designed for Toyota Red, since older Toyotas have brass(?) heater cores and the pink coolant can cause corrosion with the brass, or whatever metal that heater core is made of. The newer Toyotas come with Toyota Pink ("super long life"). The factory fill on our cars was Toyota Red ("long life"). I would not do that again, knowing what I know today. ![]() I did the coolant flush about 3 years ago and didn't really understand coolants, so I used the green coolant. Is green coolant better or should i stick with the red? Should have just done a flush in the first place, bad apple on me. I will then use the RED Toyota long life coolant and mix with distilled water. So my idea now is to do a full flush of the system before I operate the engine. What I have realized though, is that you shouldn't mix any coolants and should only switch coolant types after doing a flush. I've read so much debate about red or green coolant and which one is better and what last the longest etc. ![]() I am worried though that maybe I still have some green coolant in my system. I was not able to start the car and finish the process of adding coolant. Originally my car had GREEN coolant, I drained out the radiator but didn't do a full flush and then added RED coolant (which I had to mix with distilled water, 50/50).When filing the car with red coolant I could only fill about 5qts before the radiator was full. Now the Camry owners manual specifies to use ethylene glycol coolant which is still the red coolant. I went to Toyota to buy some coolant and the guys there said I needed red coolant (Toyota long life) and that Toyota switched from red to green coolant. So I just replaced my water pump and timing belt.
