best way to flush coolant system?

[mmashburn]

when i got the front clip, i drained the coolant out of the stock sr radiator, it was really murkey and dirty... whats the best way to clean out the whole entire system?? can you do anything w/ a garden hose and just run constant water through it until everything is flushed through?

i usually just use the water hose.

when you're filling the system, unscrew that bolt and fill the radiator until you see fluid start to leak out of that hole. Then replace the bolt, fill the radiator up all the way, and turn the car on. once the car reaches operating temperature, the thermostat will open up, and you can finish filling in the radiator if the level drops any.
