Repair an alternator if the damage is minor, it’s relatively new, and repair costs less than replacement.
ReplyDeleteReplace an alternator if it’s old, has multiple issues, or repair costs nearly as much as a new one.
Replacement usually offers more reliability and warranty.
Great question—and one that can save you a lot of money (or cost you even more if handled the wrong way 😅).
ReplyDeleteHere’s the deal on whether it’s better to repair or replace a broken alternator:
Repairing the alternator: When it makes sense
Cost-effective (usually cheaper than a full replacement)
Good if only one part is bad (e.g., the brushes, voltage regulator, or bearings)
Can work well if you trust the mechanic or are doing it yourself
⚠️ But: Not every alternator is worth repairing. If it’s old, worn-out, or has multiple failing components, repairs might just delay the inevitable.
Replacing the alternator: When it’s the smarter move
New or remanufactured alternators are more reliable and come with a warranty
Less downtime and guesswork—no hunting for which part is failing
If your alternator is more than 5–7 years old, replacement is usually the safer long-term option
Cost comparison (rough average):
Option Estimated Cost
Repair $70–$200 (if minor parts)
Remanufactured Replacement $150–$300
Brand New Replacement $300–$600+ (depending on car model)
My advice?
If the alternator is still relatively new and only one part is bad → repair can be worth it.
If it’s older, unreliable, or has multiple issues → go ahead and replace it, ideally with a remanufactured one to save cost but still get reliability.
