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...

i flushed my system using a garden hose through the heater lines, and radiator. then i used Gunk coolant flush for 20 mins and flushed it out again with the hose. then i used toyota prediluted pink coolant to fill the cooling system.
after all that, my heater works much much better than before, i'm actually looking forward to -40 degree weather to compare how it was like before.
