How Much Does an Alternator Replacement Cost?
Let’s review the costs of replacing a failing alternator:
A. Range
You can expect to spend between $200 and $1200 to replace a bad alternator.
This includes:
- New alternator: $100 to $1000
- Labor charge: $100 to $200 per hour
B. Factors Affecting Costs
The alternator repair cost varies based on your vehicle’s make and model, local labor rates, and whether you buy aftermarket, OEM parts, or a rebuilt alternator.
Other factors include:
- Alternator accessibility: Some cars have easily accessible alternators that can be replaced in about an hour, while others, like BMW, have alternators buried deep in the engine compartment. This requires removing several parts, which takes more time and increases costs.
- Amperage: The cost of a car alternator can differ depending on the amperage (electrical power) it generates and the materials used. Low amperage alternators usually use less expensive materials like copper in their windings.
- Types of electrical connections: Simple 1-wire alternators, typically found in older vehicles, are less expensive than 3-wire alternators used in newer cars.
- Additional repairs: During the alternator replacement, mechanics may discover that car parts, like the serpentine belt, a bad battery, or a battery cable, need attention. Replacing these components can increase the alternator repair cost.
Note: Alternators aren’t typically covered by car insurance, but you can purchase one with a warranty to save costs.
Is it Worth Replacing the Alternator?
Short answer: Yes.
The alternator is crucial for your car as it charges the battery and powers the ignition system.
Without a functioning alternator, the battery will eventually run out of power, causing the engine to shut down. Moreover, if the alternator’s voltage regulator fails, it can overcharge the battery, risking damage to the electrical system.
So, to prevent an alternator issue, have it replaced immediately.
Signs You Need an Alternator Replacement
Here are some symptoms of alternator failure you should look out for:
- A dead battery
- Vehicle stalling or difficulty starting the car
- Squealing or whirring noises from the engine
- A whistling or overheating drive belt
- An illuminated battery or check engine light
- Dim or flickering lights and malfunctioning electrical accessories (power windows, radio, etc.)
- Burning rubber smell from the drive belt slipping on the alternator pulley
How Long Do Alternators Last?
Alternators typically last for about 80,000 to 150,000 miles or around seven years. However, they may fail sooner due to factors like:
- Driving habits: Aggressive driving, frequent use of electrical accessories, and consistently running the engine at high RPMs can strain the car alternator.
- Environmental conditions: Prolonged exposure to heat can negatively impact the alternator, leading to internal electrical component damage and premature failure.
- Parts quality: An alternator’s lifespan depends on its quality. To prevent premature replacement, buy from a reputable brand and ensure proper installation.
5 Tips to Prolong the Life of Your Alternator
Here’s how you can make your alternator last longer:
- Follow your car’s recommended maintenance schedule to identify and resolve bad battery issues promptly.
- If your car battery is fully drained, use a battery charger to recharge it. The alternator can’t charge a battery if the vehicle doesn’t start and isn’t built to handle such heavy loads.
- Protect your alternator from fluid damage by fixing coolant, power steering fluid, or oil leaks immediately.
- Avoid idling for long periods as it strains the alternator and drains your car battery.
- When charging electronic devices like mobile phones or tablets in your car, ensure you charge them one at a time to avoid overloading the alternator.
