Do all this after replacing the head gasket and thermostat. Flush it out with plain tap water. Step 1: Use a garden hose placed in the top of the radiator inlet. Let it run until the water comes out clean. Put on the radiator cap and turn heater control to hot. Start the engine and run for at least 10 minutes. Shut engine off, wait until the radiator cools and remove the cap. Drain the radiator and repeat step 1 again. After repeating step 1 proceed to step 2. Step 2: Leave heater control to hot, and add a 50/50 mix of the correct antifreeze and distilled water to the radiator until it is full with no more air bubbles escaping. Start the engine and keep it full until you see no more air bubbles escaping. Use bleeder screws to remove air if so equipped. Install cap and you are done. Check the coolant level each day for a few days to make sure it stays full.
