Re: Sorry for repeated question but what to use when flushing cooling system out?
I used two cups of simple green.
First, drain out any antifreeze and relace with water.
1. Added cleaner
2. Ran it up to temp for 30 minutes.
3. Let it sit for couple of hours.
4. Drained it out.
5. Flushed couple of times.
Worked good.
