What is neccessary to remove the serpentine belt? I see the long threaded bolt that goes through the steering pump bracket and threads through the idler/tensioner also. Do you need to loosen all the bolts on the power steering pump bracket in order to loosen up the belt? I'm thinking that that idler or tensioner could be going bad. Are they known to make noise under load? I've got 85K and this has never been changed. Please help.
