Green Coolant?? HELP

Do it NOW what Tom said. Toyota's can not use green ethylene glycol. Look on the bottle and make sure it says "Approved for use in Toyota Vehicles"

Toyota's coolant is pink/orange..not red, not green. The main ingredient in Toyota's coolant is actually ethylene glycol, but with additives and no silicates, best for an aluminum radiator and heads/block. It's OAT, Organic Acid technology. ctownjohn, you best bet is to flush you system right away and use coolant specifically labeled for use in Toyota's. There are differences in the corrosion inhibitors and such that adding one type to another will reduce the effectiveness of the inhibitors resulting in premature failure of components such as water pump and radiator. The pink Toyota ethylene glycol has added anti-corrosion chemicals. This coolant has organic anti-corrosion chemicals (OAT) and are better for aluminum radiators and have longer anti-corrosion life. Toyota's OAT chemicals react negatively with the silicates found in green ethylene glycol antifreeze and can deposit scale in the water passages, over-thicken to the point of almost Jell_O (Just like Tom said) resulting in poor heat transfer and boil point temperature.

Thanks for the info!! I have driven about 100 miles since I put it in there. I made an appointment to get it flushed for Wed. gonna try to drive as least as possible till then. I hope I haven't caused any damage!

Can you put peak coolant in toyota camry 2005

Im sure my 1992 Lexus es300 used green coolant

Makes absolutely no difference - you can mix green with orange/pink coolant and vice versa with no problem - the Toyota people want you of course to use orange/pink coolant because its their product - the biggest concern is to exchange your coolant regularly this is more important than people think - I am an engine mechanic for 45 years

Mine has a rebuilt engine and my car is making some weird noise and I'm so worried about it I'm only 25 DRTOYOTA can you help me if so my phone number is 269-377-1946
