i had thought of using the coolant but my idea wa smore complicated. i was going to tap a coolant hose and run that line through a hole i would make at the bottom of the res. tank. seal it all up and tap that line back in. the hot tapped line would give off heat and it would be in the res tank. but it would suck if there was a leak.
where would you buy a small heat exchanger though?
