One alternator bolt loosened several inches. The shop

Customer Question

One alternator bolt loosened several inches. The shop replaced alternator because of base damage. Belt came off within 100 miles. Shop replaced tensioner pulley. I told them the alternator pulley was out of alignment. They couldn't find a bracket (don't know if they were talking upper or lower). Belt made much noise shop said from side of belt riding. Shop added washers on lower pivot bolt to shim alternator. Belt started shredding within 3 days of little driving. Tensioner pulley also looks slightly askew. Suspect twisted lower alternator bracket. I have repair manuals but don't know how to remove lower alternator bracket. Book also doesn't say how to remove the windshield wiper housing or belt tensioner pulley. With bolt removed from top of alternator mount bracket to the engine air intake plenum, may be possible to twist the alternator plate or lower bracket.

Hello and welcome to JustAnswer!

The bracket that the bottom of the alternator bolts to is thick aluminum so it's not likely to be bent. It may be broken or damaged from the alternator breaking or possibly from the repair. Replacing the bracket will require removing the alternator and power steering pump, about half a day's worth of work with the van on a hoist and all proper tools.

It looks like they may have just replaced the tensioner pulley which won't help an alignment issue. What happens is the stud on the tensioner itself will bend over time causing the whole tensioner to lean and then the belt will walk off.

Was the whole tensioner replaced or just the pulley?
