I just purchased a camco do it yourself winterization kit to be used on my challenger 1800. Someone told me that all you have to do is connect it to the lower flush port, start the engine, and let the antifreeze flow in using gravity. My question is, if the hose is connected to that port will the engine draw the antifreeze in or does an addition hose need to be connected to give it pressure?
