I'm working on my 440 today, and it took me 35 minutes to get the ring clamp off of the upper connection of the lower radiator hose. These things are so hard to work with if they're not in a perfect position to get the removal pliers onto them. They twist and move around and the pliers keep popping off. These are a good set of pliers too. Klein tools brand, purchased from McMaster-Carr. Maybe someone knows of a better tool, I'd really like to get my new hoses on with the original style ring clamps. The tool I have is pretty useless. If you use them in the normal position, the handles are too far apart and you can't squeeze them to get the ring opened up. If I use them in the slipped position, I get the leverage I need to open the rings but they don't open enough to go over the lip on the fitting. I posted a picture of them for reference.
