Signs of a failing alternator
- The battery light comes on while you drive.
- Headlights or dash lights dim, flicker, or brighten when you rev the engine.
- The battery keeps dying, even a new one.
- A whining or grinding noise from the front of the engine.
- A burning rubber or hot electrical smell.
Why the price starts from $140
On many cars the alternator sits at the top of the engine and comes out in under an hour. On others it's buried under brackets, the intake or other parts, which takes longer.
We give you the exact labor price for your vehicle before starting. Trucks, V6/V8 engines and European vehicles are quoted.
Test first, then replace
A weak battery, a corroded cable or a slipping belt can look exactly like a bad alternator. We check the battery, the cables and the charging output before recommending a new alternator.

Questions
How much does it cost to replace an alternator in Douglasville?
Labor starts from $140 depending on the vehicle. The alternator part is separate, and there is a $45 service call per visit.
Can an alternator be replaced in my driveway?
Yes, on most cars and small SUVs. We bring the tools and do it at your home or work.
How do I know if it's the alternator or the battery?
If the car dies while driving or the battery light is on while the engine runs, the alternator is likely. If the car won't start after sitting but runs fine once jumped, the battery is more likely. A charging test confirms it.
Should I replace the serpentine belt too?
If the belt is cracked, glazed or squealing, it makes sense to replace it while the alternator is out. The belt is $75 in labor.
