Take off the lower hose from the drivers side of the radiator. After all that crap comes out, put the hose back on. Fill er up from the hose. Drain it again by taking off the hose. Fill her up with 50/50 antifreeze/water. Turn it on with the radiator cap removed, watch until the level lowers once the thermostat opens up and add until it's full.

hey if ur famaliar with Queens goto Yellnick Rads, for 50 bucks he cuts it open and cleans it all out, i did that to a stock rad like 3 yrs ago and it dropped my temp by 20 degrees. or do it urself just pull the rad out flush both ways until water is clear, also get some condenser cleaner from any ac supply, and clean the outside of rad and condenser

Go to WalMart or AutoZone and get a Prestone flush and fill kit, it has a Tee that splices into your heater hose so you can back flush the cooling system with a garden hose, and a diverter that snaps into radiator filler neck. Get a jug of radiator flush and follow the directions, then back flush. When your done you add antifreeze into the tee and it displaces excess water out of the radiator filler neck, insuring system is completely free of air pockets. I have these on all my vechicles and flush them every two years. I can flush the radiator in 20 minutes without any tools, and without even getting dirty.
