So the little plastic neck on my radiator is slowly leaking, and my car is running a little hot. I'm assuming the system isnt pressurizing and it's going to only get worse. Anyway, I got a radiator from my work (Napa Auto Parts) and I'm probably going to install it next week when I get back from vacation. Anything I need to know that's radically different or would make the job any easier on these cars?
