flush and replace radiator
The way I flush mine is open the drain on the RSF bottom of radiator allowing the fluid to start draining. Then I insert a water hose in to the expantion tank and turn it on slow so it will not flood out. Allow the car to idle for 10-15 minutes or until the water runs out of the plug clear. Turn off the hose and allow the radiator to drain, close the plug and fill with a 70/30 mix. 70% water, 30% antifreeze. Depending on your climiate you may need to add a little more antifreeze. Check with a gauge. DO NOT fill 50/50.
Brakes, have a professional do this for you!
