I'm trying to change my water pump, but I can't loosen the tension pulley to remove the serpentine belt. The tension pulley has a square hole that I can't fit any sockets into, what kind of tool do you need to loosen the tension pulley so that i can remove the serpentine belt?
What tool do I need to loosen the tension so i can remove drive belt? on 2003 Chevrolet Monte Carlo
Maybe if you used that ratchet you have WITHOUT a socket on it,, the squre part of the ratchet might fit into the "square hole" in the tensioner!
