On many vehicles,you cannot access the clamps with anything BUT those cable type pliers!...the car makers have sadistically located many upper and lower radiator and heater hoses connections in impossible to reach (or even SEE) places ,where you cant get a screwdriver or socket on a regular worm gear hose clamp on one to tighten or loosen one.......................................................................................................personally I hate the springy type clamps,they dont hold tight enough sometimes,and more than one I have seen rust and fly off,allowing the hose to pop right off....they can fly out of the pliers and stick in your eye too,if your not careful....but you have no choice but to use them on many vehicles.....its just another step backwards adopted by car makers IMO...to make servivcing them a real nutcracker for the average backyard shadtree mchanic...forcing you to buy another "special tool"...
