Any of you guys have any tips on pulling out the radiator? 2014 GMC 3500 D/A was in a wreck and radiator has a small crack/slight leak. My main question is do I need to pull the fan and plastic shroud to be able to pull out the radiator or is there a way to do it with the fan on? Can I use an air chisel on the fan nut if I need to like I did on my 99' 7.3? Thanks All!! I used to have an 04.5 lly that I sold a few years ago and the only way I could really afford an lml was to buy one wrecked, so here goes nothing!
