Bolt holding alternator to car sheared off not once but twice...this takes out powersteering but more importantly only have 20 minutes of drive time without any radio/lights,etc on because the battery can't charge...this problem has occurred twice driving on a straight road on my way to work stranding me twice. Why does it happen and how can it be fixed right so I can put this behind me? Just yesterday I had to borrow someone else's car because when I started mine up it made a new clicky whapping noise which went away after I drove it about 600 yards,but it didn't sound good and intermittently I smell burnt rubber.
broken alternator bolt on 2002 Subaru Impreza Outback
Asked by for the 2002 Subaru Impreza Outback
Really need to determine WHY the bolt is breaking. What is putting so much strain on the bolt that it snaps, this is unusual for a Subaru. I have worked on many. Is your A/C compressor turning freely, sometimes an A/C compressor or anything that is also driven by that belt, including the Alternator, can start to wear out and cause too much drag and that will shear off a bolt. Inspect carefully all the devices that are being driven by this belt and make sure that they all turn freely and are properly aligned. Also, turn on and turn off your A/C and see if that effects anything, and remember, your A/C is on when you use defrost!
Thanks dandd for the insight;the belt ended up shredding apart;the bolts didn't break and I've only driven it twice since my mechanic replaced the belt and checked the alignment of all the devices...not sure if the A/C compressor was investigated but now something to check...thanks. NURSEBEANS
