Flush with compressed air and water, very simple. Take and old rad cap and blow out the valve so it's always open. Rig up a connection on that small nipple for your air compressor and household water line. Remove the lower rad hose and replace with an old lower rad hose that has had a T-fiitting inserted in it somewhere between the ends, from that T-fitting run a length of hose long enough to go to a container that can hold all the fluid that's going to be coming out. Now open the rear bleeder and both heater valves, connect your air line and turn on the pressure slowly, the fluid will be pushed out, some in the engine may still reside so start the engine and run for a minute so the water pump can clear the engine of fluid, when no more fluid is coming out, stop, disconnect the air line and connect your water line, turn on the water at full pressure, let run for 15 minutes or so, starting the engine and running for a few minutes to warm up slightly, shut off engine, shut off water disconnect and repeat the air procedure. System is now as clean and empty as you will ever get it. If your system is unusually dirty then a bottle of rad flush should be added prior to this procedure following the directions on the bottle. Fill as in my previous message.
