[QUOTE="Jebadias, post: 16078625, member: 87819"] I don't remember everything. Off the top of my head... The instructions online are pretty good but there are a few issues. -[b]Upper radiator hose[/b] - Boss or GT, that thing is a hot mess. You must piece it together and it is easy to spring a leak. You will have to cut a hose off of a plastic "Y", you will know what I mean when you see it. DO NOT OVERTIGHTEN when putting the hose back on! It is easy to do and the thing is insanely expensive. -[b]Overflow tank[/b] - Everybody says the overflow tank is junk. I still tried the stock one. They were right, it leaked for me too. Try the one that comes with the kit if you want... If it turns out bad buy the one from JPC. - [b]Refilling coolant[/b] - be super extra careful that you get all the air bubbles out of the coolant system. I have no idea how long I screwed with it, just to get down the road a few miles and overheat. Better yet don't be cheap like me, take it to a shop and make them get the air out. It took a very long time to get right, a job made harder because the upper hose that I spliced together had leaks. - [b]Fan Shroud[/b] - The Boss radiator is larger than the GT. When you cut enough from the shroud to look like the picture in the directions just understand you still need to go two or three times that amount.
