so mikey, are you useing the Flex-lite fan? their small one I put on my 83 covers about 60% of the rad. too. so I put on two! one on the inside and one on the front. had to cut the body cross saprot to make the one on the front fit, but I just welded in a pice of 1X1 tube to takes its place. and now it works fine! even when I was towing my 2.5K tent trailer up the siskues? on I5 out of Oregon. highest point on I5! and it was 94 in Ashland that day!
