hey guys im running a 02 lq4 and useing a 02 vette radiator it does not have a provision for the steam line half way down it only has a provision at the top that would go to your overflow tank. so where would be the best place to run it does it need to be down low in the coolant or can i get a radiator cap that goes in the top line that has an over flow and hook it there i just don't want overheating issues
