The water outlet, also called a petcock is located near the lowest point in the cooling system and is used to drain coolant from the engine. The petcock typically has wings, which are designed for better grip when turning the valve. If coolant is leaking from this point, it may be the petcock is partially opened and might need only to be closed completely to stop the leaking. The petcock is press-fitted into the bottom of the radiator. A leak around the petcock can be caused by a crack around the collar or a solder joint that has broken. Have a radiator shop pressure test the radiator to make sure there are no other problems with the radiator, such as other cracks. During a pressure test air is pumped into the radiator and then it is dunked into a water tank. Air bubbles escaping from the radiator indicate leak sites and will need to be repaired. --mark
