I need to flush my engine coolant and saw someone on here last year who switched over to the green coolant. Is this something that I should do? I need people with knowledge, not someone posting saying that the green is prettier. Opinions please.

Yup.The orange is long life and is premixed most of the time (read label).Good for 100K miles or 5yrs I think.In trucking long life eliminates
the need for other additives (dca,sca).I would stay with long life,it's better and won't leave green goo deposits.They can't be mixed either.
I could go more into details but what i've learned on coolant till now applies mostly for trucks so don't wan't to write wrong info.

Just to expand on one thing said by Hab, they REALLY cant be mixed. If for some reason you would want to swap over you need to do a very good job of flushing your radiator / cooling system. When the red and the green are mixed they congeal, you got jello in your system which for some reason doesn't tend to work very well....

Yeah,there's alot of truck drivers from "far away" that don't understand the difference between the two and keep mixing them.Turns into
brownish sludge.Is there red long life?I think there all orange.The only red coolant i've ever seen is from detroit diesel and it's reg
coolant that's prechaged with all the additives (useless for sleeveless engines).

Ya, I didnt hear anything about not mixing them until last summer when a guy from my church did it. It cost him some $$ to get it fixed at the dealer.

Thanks guys. I'll stick with the orange colored coolant.

why would you ever buy premixed coolant? its like a dollar cheaper, but you get half as much.

You can buy pure long life. Just need to search for it a bit. Surprisingly, it wasn't at the normal autoparts stores when I looked for it last year.
