flush cooling system?, how to do it properly? Options

[Hanyo]

how do you properly flush the cooling system of a car?

I know the basics like hook up a garden hose and run water through the system as the engine is runing and heater on to help remove all the rust and containaments in there.

But what do you do with all that radiator fluid? You can't just let that drain into the storm drains.


And your not suppose to get hard water into the cooling system, that is why distilled water is needed. And flushing the cooling with gallons and gallons of distilled water will be very costly....

What about those chemicals you can buy?

What is the best way to do it? To be honest i dont trust those jiffy lube shops to flush my car, they probably wont use distilled water...

you're all acting like the cooling system needs to be perfect and sterile and the tiniest bit of minerals or chlorine is going to to totally destroy the engine, no matter what theres ALWAYS a little of something in there. right from the factory theres a little oil in your cooling system, some dust, some dirt, etc.
