My radiator has gunk all in it and my truck is overheating and when it overheats brown stuff start a leaking out of the radiator cap. My truck has just started overheating n my heater started blowing cold air. I looked under the hood and noticed brown fluid coming out of the radiator cap and there s no leaking from anywhere else. When the truck cooled I opened the radiator cap and there is a lot of build up n the radiator. If I flush the radiator will this help with the overheating?
