Bad belt or tensioner? Sign In

96 jeep cherokee 60k. Somethings squeaking. Belt doesn't look too bad could it be the tensioner? The noise is annoying. If its the tensioner, can I just spray some wd-40 on it(its one of the manually adjusted tensioners)?

WD-40 on belt may quiet a belt temporarily but now harder to check tension. Check longest stretch of belt between pulleys for how much it can move. Without the WD-40 now you can't just go by turning the alternator fins as they should be hard to turn if belt it tight enough. Too tight, you burn out pulley bearings.

Other: May not be belt tension at all. Take belt off and spin pulleys. Good ones have no lash, sounds or gritty feel when spun by hand,
