Had a hose off the water pump go today. have cooling system/flushing questions

there should be a drain plug/fitting on the pass side of the radiator towards the car. Either pull the plug, or screw the fitting in and it drains Now, the consensus is that you will not get those friggin plugs out of the block...several have tried and had no luck - they're stuck after years of heating up, cooling down, etc. By the way, the hose goes in the radiator neck(where the cap goes).

What I was instructed to do was to fill it up w/ water, drive it so the t-stat opens, go home, let it cool off, drain all you can--drain the rad. via the plug and also pull the hose(you can drain it all from the hose, but that's sometimes messy). Fill it back up, drive, drain, and keep doing this until it starts draining clear.

You might consider running a distilled water/anti-freeze mix as tap water causes corrosion and junk in the rad; however, run what you want. You can get a 3 gallon case of distilled water at wal-mart for like $1.80 or something, so you might spend $10 on water for the whole process.
