It’s time to install the replacement alternator once you have all the necessary tools and the alternator. 30 minutes to 2 hours may be needed to complete this task. Your level of expertise and the type of Toyota you own are factors. Some alternators have low engine bay mountings. Others are considerably easier to reach.
This set of guidelines is based on the Toyota Camry. You might be able to use this guide if you have another Toyota model. But be prepared for some differences.
- Detach the hood.
- Negative battery cable should be disconnected from the battery and set aside.
- Loosen the belt tensioner by using the 19mm wrench with the long ratchet handle. To remove the belt from the alternator pulley, push it downward.
- From the alternator, unplug the electrical connector for the control harness. (Several wires from the control harness lead to a multi-wire connection.)
- The power wire that is linked to the alternator is covered by a small plastic cap that should be removed. (The thick red cable that connects the alternator to the battery is the power cable.)
- After removing the cable from the alternator, remove the 10 mm nut.
- The wire bracket is secured to the alternator by a second 10 mm nut. The wire bracket should be removed and then put away.
- The alternator is fastened with two bolts. Take those away.
- The alternator should be moved out.
- Reverse the removal and installation of the replacement alternator.

Between $68 and $86 is the expected range for labor costs, while $322 to $391 is the range for part costs. Taxes and other fees are not included in this range, nor are your particular model year or geographic area taken into account.
Can I swap an alternator out on my own?
You can replace an alternator on your own in around two hours on average, however this may vary a little depending on your level of auto technician expertise. Timing may vary slightly and you might have to leave the car for the day if you bring your car to a shop to have the alternator replaced.
Dim or Overly Bright Lights
Your electronic gadgets receive erratic voltage when an alternator starts to fail. This typically manifests as under- or over-performing equipment, such as headlights that are either too dim or excessively bright. Additionally, you can see lights that erratically switch from bright to low and vice versa.
Dead Battery
A dead battery may occasionally just be a dead battery. After a few years of use, it has either reached the end of its lifespan or you may have unintentionally kept the headlights on all night. A dead battery may occasionally indicate a problem with your alternator, though.
When the engine is operating, a defective alternator won’t adequately charge the battery, resulting in a quicker than usual discharge of the charge. Jumpstarting the vehicle is one approach to determine if the problem is with the battery or alternator. If your car runs after being jumpstarted, your battery may need to be replaced shortly. If the car dies again soon after being jumpstarted, it may indicate that your alternator isn’t providing enough power to the battery.
Slow or Malfunctioning Accessories
Accessories that operate slowly or not at all are frequently a sign that your alternator isn’t providing enough power to your car’s electronics. You might have an alternator issue if you notice that your windows roll up or down more slowly than usual, if your seat warmers seem “off,” or even if your speedometer and other instruments start acting strangely.
If the alternator isn’t producing enough electricity, many modern cars feature a priority list of equipment that informs the onboard computer where to cut power first. In this manner, if your alternator fails while you’re on the road, your radio or other unnecessary equipment will continue to function before your headlights.
Trouble Starting or Frequent Stalling
As was already noted, if your engine is difficult to start, your alternator may not be charging the battery. This means that when you turn the key in the ignition, all you’ll hear is a clicking sound instead of the purr of your engine.
On the other hand, if your car repeatedly stalls out while you’re driving, it can mean that the alternator isn’t supplying the spark plugs with enough power to keep the engine running.
Growling or Whining Noises
There are many strange noises that cars make; some are harmless, while others may be signs of major technical issues. You should have your alternator checked properly by a professional right away if you ever hear growling or whining sounds coming from underneath the hood.
When the belt that rotates the alternator pulley falls out of alignment or rubs against the pulley’s side, a growling or whining sound is produced. If the bearings that spin the rotor shaft are failing, you can also hear this noise.
Smell of Burning Rubber or Wires
A burning rubber or wire stench could be a sign that your alternator’s components are beginning to wear out. The drive belt for the alternator may eventually wear down and give off a terrible burning rubber odor due to the constant tension and friction it experiences as well as its proximity to the hot engine.
Similar to an electrical fire, your alternator may smell burning if it is overworked or if it has frayed or damaged wiring. Wires in an overworked alternator heat up dangerously as a result of trying to force too much energy through them. In addition to creating resistance to the passage of power, damaged wires often heat up and smell bad.
Battery Warning Light on Dash
When the battery warning light appears on the dashboard, it’s frequently believed to indicate a problem with the battery. The battery warning light, however, suggests that there might be an issue with your car’s larger electrical system, which includes the alternator.
The normal operating voltage for alternators is between 13 and 14.5 volts. The battery warning light on your dash may come on if your alternator is malfunctioning because its voltage may fall below its maximum level. Similarly, depending on how much strain the alternator is under, the battery light may also come on if the alternator is operating above its voltage limit.
The alternator may fluctuate in and out of its intended voltage capacity depending on the electrical demand from your car’s accessories (headlights, wipers, radio, etc.), which might cause the battery warning light to flash on and off. Although it can seem like a minor inconvenience, it’s preferable to have your car inspected for alternators than to become stranded on the side of the road.
How long can a vehicle operate without an alternator?
Simple mechanics apply. Your car’s battery cranks it into motion. The alternator, though, is what keeps it going. How long will a car operate without an alternator, and what can you do to extend the vehicle’s ability to work, for the unfortunate folks who discover that this crucial component of the vehicle is failing?
Your automobile will only run for up to two hours and as little as five minutes without this crucial component. The most run time will be experienced by those driving an older model car or a diesel vehicle. Additionally, you can extend the life of your battery if you keep the engine running until you reach your destination and make sure to turn off as many superfluous electronics as you can.
Can an alternator be changed at AutoZone?
To make sure the charging system is operating properly, you can take the car to AutoZone and have the alternator examined there. Depending on the precise year, make, model, and engine of your vehicle, some of these instructions may change somewhat.
How long does the alternator on a Toyota Corolla last?
It is crucial to go over the fundamentals of an alternator operation first. The alternator, which is attached to the engine, is responsible for giving the battery power. It maintains the car’s electrical and electronic systems operational and charges the battery continuously.
The alternator exerts the most effort of any component in your car, therefore ultimately it will burn out. An alternator lasts seven years or roughly 150,000 miles on average. The quality of the component, the state of the car as a whole, and the number of electronics in operation are some of the variables that might affect the alternator’s lifespan.
Does it make sense to replace an alternator?
If the alternator is broken, it is typically wiser to replace it totally. Even though they can be expensive, new ones are generally preferable than remanufactured or rebuilt alternatives. Since the mechanical components have a lot of miles on them, they most likely won’t last as long as a new one.
Check for a remanufactured or rebuilt alternator at your neighborhood auto parts store if you can’t afford a new one. If a mechanic is handling the installation, be sure they provide you a brand-new alternator rather than trying to save money by using a refurbished or rebuilt one.
A high-output alternator, which is more expensive, may be required for some vehicles with increased electrical needs, such as ambulances or vehicles with sizable, power-hungry sound systems.
Depending on the type of car, the cost of the parts varies widely, but it often falls between $150 and $300. An OEM alternator for a more recent Mercedes or Audi can easily cost close to $1,000 as more costly automobiles would typically demand more expensive parts.
Since certain alternators are simpler to access and require less time to work on, labor expenses also vary, but budget between $200 and $600 for the work.
Expect to shell out anything from $350 to $900 in total for an alternator replacement. In most circumstances, it will be less expensive to have an independent mechanic handle the work than a dealership.
How long does an alternator change take a mechanic?
We’re happy to see you moving toward mending your Jeep! It will take a professional roughly two hours to replace an alternator.
There may be a delay before a technician can work on your vehicle, so it doesn’t mean it will only be there for two hours. Also, it will take longer if the shop needs to order parts.

How does your alternator malfunction?
Both mechanical and electrical power sources are used by modern autos. The mechanical force required to move your wheels is produced by your engine through combustion. While a number of other devices, such as your radio and headlights, run on the electricity provided by your battery.
The alternator, which converts mechanical energy into electrical energy to keep the battery charged, allows these two systems to communicate with one another. Numerous issues could arise if an alternator stops functioning properly. In this post, we’ll look more closely at four typical signs of a failing alternator.
1. Vehicle Won’t Start
A car that won’t start almost invariably has a dead battery. If you jump-start the automobile and it starts up normally, the battery is probably the source of the issue. Sometimes the battery may just have run out, as may happen if you neglected to turn off your lights. When this occurs, the issue is resolved by jumping the battery and letting your car run for a while.
You could need a new battery if your automobile starts and runs after being jumped, but won’t start the next time you try to start it. Once the car is started, it keeps running, so you know the alternator is still able to function. Instead, it appears that the battery is unable to maintain a charge when the engine is off.
If your engine stops again shortly after jumping the battery, your alternator is most likely at blame. Your alternator may have even fully failed. A fresh battery installation might temporarily solve the issue. However, once the replacement battery’s power has been used up, you’ll be stuck with a non-starting car.
2. Engine Sluggishness
A car that won’t start is almost always the result of a dead alternator. But before things reach that stage, a number of additional issues could arise. An alternator that is broken or dying might only function intermittently. As a result, even with your engine running, the alternator might not be able to keep your battery fully charged.
Your automobile can stop out as a result at strange moments. The fuel injectors, which depend on electricity to function, are frequently the immediate cause of such stalling. The fuel injectors may not fire, resulting in an engine stall, if a defective alternator is unable to maintain a steady charge in your battery.
3. Electricity Problems
A failing alternator can cause a variety of additional electrical problems. Generally speaking, these problems show themselves as a reduction in performance. You might observe, for instance, that your headlights appear to be darker than usual or even that their brightness changes mysteriously.
Dash and dome lights that may flicker or appear dim are further indicators. Windows that operate automatically could operate substantially more slowly than usual. Alternatively, your radio and/or entertainment systems might periodically turn off by themselves.
4. Strange Sounds
Poor alternators frequently make loud or peculiar noises. A belt is used to transfer mechanical energy from the engine to the alternator. You can hear strange squeaking noises coming from under your hood if this belt has become out of alignment or has been worn down severely. The alternator may not turn quickly enough to produce enough power if the belt is worn.
The internal stator of the alternator can spin alongside the belt thanks to bearings inside. These bearings start to hum as they corrode and wear over time. As the bearings deteriorate further, this sound gets louder.
