I really didn’t think the lower radiator hose was going to be difficult. It would help if GM didn’t do away with the radiator petcock. Great word btw. My original had it, but the new OEM one I installed did not. It also would help if I didn’t have the pump for my intercooler right there. I also must have had the transmission cooler lines disconnected when I last installed the clamp at the radiator side because I almost couldn’t get it off due to its orientation. And then the cold air intake for the blower was in the way. Not much room from above so I pulled the wheel and was barely able to get the spring clamp pliers on and wiggled and grunted until that thing came off. Now I’m taking a break because even a half hour later, there’s still coolant dripping out. And it’s starting to get hot outside. This might be a 2 day project.
