OK, I feel like a real idiot for having to ask.... but.... How do the connectors on an 07 automatic cooler lines (the ones going to the radiator) disconnect? I have the factory manual and it would seem line you squeeze in a tab and pull them loose? Then elsewhere it states you need a disconnect tool. Seems like the same kind of thing for the fuel filter, also. So... how exactly do you use this tool? I've seen them in the auto parts stores and they don't have any instructions [mad]. I'm stumped. Anybody got any photos of how these things work or instructions??? Any advice appreciated!
