Note If youre using a pump/reservoir combo with both inlet and outlet both at the bottom of the unit (like I am with the Heatkiller Tube 200 DDC), some of these tiny bubbles will be grabbed by the outlet flow of coolant and sucked back into the system before they can float to the air pocket. It is critical to take these steps in order for the system to function properly and for no air to escape. Once the air is pushed out, there will be a significant drop in the coolant level. The water is obviously heavier and denser than air, so gravity will help, but there are problems that gravity cant overcome by itself. Complete Explanation, How To Slope Pvc Drain Pipe? A bleeder valve is usually found somewhere inside the thermostat housing or in the coolant hose that connects to the heat exchanger or expansion tank. 9 Answers.
