Alternators – New, Used Or even Rebuilt?
There are several factors when having to replace your alternator. Brand new alternators are expensive and in some cases could cost more than your vehicle is worth. Used, rebuilt, and new alternators differ in price significantly. Making the decision can be difficult because there doesn’t seem to be an average life span for an alternator. Alternators can last for Two decades or they may only last for 2. Knowing everything about alternators will help make the right choice, however, the amount of money in your wallet is a very important factor as well. The best goal is to not get stranded on the side of the road since your alternator fails.
Rebuilt alternators are typically okay as long as there is a warranty. You might be surprised to find that the only thing you are buying with a rebuilt alternator is the warranty. The extent of some rebuilt alternators is only a very good cleaning of the part, perhaps some fresh paint, and this causes it to be “look” new. If it is found that some of the replaceable components should last the length of the warranty than they may not necessarily be replaced. Some auto parts suppliers have even taken to testing their “rebuilt” alternators prior to selling them because of the many failed units right off the shelf. Typically a reconstructed alternator should have a new bearing, current regulator, and brushes. These are the simplest and cheapest components to replace. The result is a much more affordable alternator.
A used alternator might be an option for you. They are typically the cheapest but also the most unreliable. This is due to the fact that it could have been sitting for an undisclosed time period. During this time of inactivity, the opportunity of corrosion is high. The contacts and bearings are first things to suffer because of a static alternator. A component like this may have a mystery amount of mileage. The general consensus is to stay away from an used alternator if it has not been thoroughly inspected and tested.
If you drive an old car that you are barely keeping alive, you will be blown away by the typical price of a new alternator from the dealership. Dealerships sell brand new alternators that can cost upwards of $600, so finding a new aftermarket alternator with all brand new components might be the best mixture of cost and quality. The beauty of a new aftermarket alternator is that you discover you are getting all the components new, they come with competitive warranties, as well as being direct replacement parts that have to produce the outputs that the vehicle requires. You may even find the option of getting a more powerful alternator which is always good to have especially if you are running high amperage accessories.
Following everything is considered, you might come to the conclusion that the dealer suggested alternator might get you the most reliable part. Is the extra cost worth it? That’s your decision- if you are looking for my estimation, the answer is probably not. I would select an aftermarket alternator as the finest combination of price and reliability.
