So i was talking on The phone, and i am working on a old bronco and my 08 jku i grabbed the bottle of green antifreeze and put a half cup of it in my radiator before i realized what i had done. I have not started the car since doing this. Do i need to flush the radiator? Was the amount i put in so little it will be fine ? Since i didn't start vehicle will a radiator only flush be fine to correct issue?
