If I were to do it again i wouldnt have put the holes for the tubing in the lid. It was a real ***** trying to get the tubing on the pump. I'd suggest have the tubing come out the side instead, but as close to the top of the cooler as possible.
@ Myles, that really sucks about your AC rad. Look on craigslist and kijiiji, I found mine there for 20 bucks.
