Q: Accessory belt on 1997 Chrysler Town & Country

Alternator pulley was squeaking, driped some water on pulley, noise stoped. Belt came off, not fraid or broken. With belt off, pulley turns very easily on alternator. I have a diagram for the belt but not sure what I have to loosen to get it back on. Also, why would pulley sqeak with belt on but not with belt off? Thanks!

The belt may squeak if the belt is cracked, contaminated, glazed or misaligned or if the belt is inadequately tensioned. The belt on your T+C has an automatic belt tension these tensioners usually have a square drive hole that you can put a 3/8 drive extension in or you put a socket on the tensioner pulley pulling against spring pressure to allow slack enough so to put the fan belt back on. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subrcription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try and get an online repair manual subscription.
The belt tensioners often fail and no longer adequately tension the fan belt.
