The garage stays warm enough scares me! I have a heater in the garage, but it does not have a thermostat, and since it is esentially an open flame on the wall, it scares me to have it come on on it's own. It seems like such a waste to throw out a toxic substance like
antifreeze when I am just using it to store over the winter. Can you jsut drain the cooling system and then fill it in the summer? I would think that this would have potential corrosian issues being exposed to air, and my luck I would have a pocket of water that would freeze.
