Flushing the radiator.

Noticed some rust in my radiator fluid turned water little brown. Is there any thing that is good to use to flush out the block and radiator? I have a electric water pump.

I don't see any benefit to bleach in the cooling system. I knew I seen this before,you can get this at Pep Boys.

Re: Flushing the radiator.

mantaguy is right there is no benefit flushing coolant system with bleach "Prestone" does make a flush for the coolant system one thing that I would add to make it easier is this kit........http://contentinfo.autozone.com/znet...KFOAA/image/3/
