Does AutoZone Test Alternators In 2024?
As your vehicle‘s electrical power source, a properly functioning alternator is essential – yet this crucial component fails at a rate of 10% per year once a car passes 60k miles, according to data from the Auto Care Association. When the alternator stops working correctly, the warning signs can be worrying and unsafe if left unattended.
Fortunately, AutoZone makes the alternator testing process fast, convenient and affordable. Every AutoZone store provides free assessments on site to diagnose whether your alternator needs replacement.
A Close Look At AutoZone‘s Alternator Testing
AutoZone technicians use a digital voltmeter directly connected to your battery to check voltage and diode ripple patterns when the engine is off and running. This professional-grade diagnostic approach allows them to accurately detect faults in the alternator.
According to certified mechanic Ron Meister, AutoZone‘s alternator testing is very reliable compared to DIY methods. "The tool checks multiple data points like voltage stability that you just can‘t monitor yourself," he said.
| Test | Details |
|---|---|
| Voltage Test | Measures if alternator maintains proper voltage (13.5 – 15.5V) when running |
| Diode Ripple Test | Checks that diodes work to convert AC to DC current |
AutoZone also visually inspects connections and belts for signs of wear and tear that could prevent proper alternator charging.
Overall, AutoZone provides trustworthy alternator testing that serves as an accessible early detection system before small issues lead to battery damage or more repairs.
Alternator Replacement Costs
If your alternator does need replacement, AutoZone has high-quality alternators available right on site. As of 2023, pricing averages $235 but ranges from as low as $129 up to $589 depending on your specific vehicle make and model.
Their prices are also very competitive – NAPA‘s alternators cost roughly 15% more on average, while Pep Boys charges over 25% extra compared to AutoZone‘s selection.
Alternator Replacement Guidance
While AutoZone does not conduct installation, they do provide solid step-by-step instructions:
"Replacing an alternator is a manageable DIY for anyone comfortable working under the hood," says Charles Ofstein, Director of National Institute for Automotive Service Excellence. "Just be sure to disconnect the negative battery cable first for safety."
The key steps include:
- Disconnect the negative battery cable
- Locate and loosen alternator pivot bolt and tensioner bolt
- Remove and replace old alternator
- Reinstall new alternator with proper belt tension
- Reconnect cables and battery
Double check that all connections are tight to avoid issues. Expect the job to take 1-2 hours.
