I had to dump it to change the intercooler pump. I put a 50/50 pre mix back in with water wetter. Is that ok. I know the old stuff was green. But didn't know if it came mixed from the factory. New stuff is Orange It should not make a difference right?.

 

it's all the same, I run less anti-freeze here in SoCal, water cools better than anti-freeze, I have maybe a 5 to 1 mix, just enough anti-freeze to prevent rust
