Is buying a used alternator a good idea?
Regarding this, is it OK to buy a remanufactured alternator?
Rebuilt alternators can be up to 25 percent cheaper than buying a new alternator. One problem is that good quality in a rebuilt alternator means more money---the cheaper the rebuild, the more likely that the alternator will break again. As a result, it might be more cost-effective to simply purchase a new alternator.
Likewise, is it better to rebuild or replace an alternator? New: A new starter or alternator provides you with a working system where all parts are at the same stage of wear and tear, but it's often the most expensive option. A rebuilt system won't have all its parts at the same state of wear and tear, but it's an affordable alternative to buying a new alternator or starter.
In this way, how long will a rebuilt alternator last?
When people have their car alternator replaced, the expectation is that the repair will last at least as long as the expected life of the new alternator, four to five years or anywhere from 50,000 to 100,000 miles. Plus, like many auto repairs, replacing an alternator is not cheap.
