It’s really simple to replace the alternator if you know where it is. The idler holds the serpentine belt firmly in place, therefore you will need to remove it. With one bolt, the tension on it can be released. You can remove the alternator, which typically has three bolts, after that is loosened. You can manipulate it out for replacement after those are gone. In order to begin, disconnect the battery.

How is a step-by-step alternator replacement performed?
Every job has a difficult section, and removing the belt from the pulley is the difficult section for replacing an alternator. Your vehicle has a tensioner pulley somewhere on it. It must be moved far enough for the belt to come off the pulley. We had to use a tool to draw back the typical spring-loaded GM tensioner on our 1995 GMC. Some vehicles include rod-end or screw-type tensioners, which work by applying pressure as a bolt is turned through threads to change the length of a rod. To remove the belt in this situation, simply crank the bolt or rod end with a wrench or socket until the strain is released.
In our situation, we seized a Craftsman 17mm Cross Force wrench and applied considerable pressure. That would typically be a horrible experience, but the Cross Force was created specifically for such a scenario. The Cross Force wrenches have a 90-degree twist in the centre, which causes you to push on a flat surface. So we could use more force without feeling uncomfortable. We simply fought it till the belt freed itself.

How can I fix a non-charging alternator?
To verify the operation of your alternator, you can follow a few simple procedures.
- While the engine is running, gently tap the alternator with a hammer; if the charging returns to normal, the carbon brushes within are worn out and require replacement.
- Examine the huge power connection going to the alternator as well as the nearby battery’s typically large 40-60 amp fuse.
- Between the engine and the body, inspect the ground cable.
- Verify the alternator is rotating along with the engine and the serpentine belt is in place.
- Examine the charging light wire and the little power supply wire. You can measure it with a multimeter, but to do it correctly you might need a wiring diagram and some knowledge of car electronics.
- To make sure they are not harmed, you can measure the voltage regulator and the diode assembly. Although some alternators can be used to replace these, buying a new alternator these days is frequently the same cost. What you decide is more worthwhile is entirely up to you.
How can my alternator be tested?
- Purchase a multimeter.
- Select DCV (DC Volts) above 15 on your multimeter.
- Make sure the positive and negative terminals on your alternator are clean.
- Connect the red cable of the multimeter to the positive terminal and the black cable to the negative terminal.
- An optimal alternator reading should be about 12.6.
The location of the alternator
The serpentine belt in your engine powers the alternators, which are situated near the front of the engine. The power from the crankshaft and serpentine belt is used by alternators to move magnets across a particular surface made of wires and cables known as the conductor.
Can I put in an alternator on my own?
Putting your tools together is the first step in changing the alternator in your car. Fortunately, nothing too difficult or pricey is needed for this. The owner’s manual, some eye and hand protection, a few wrenches and sockets, and a spare alternator are all you need. You don’t need to replace a serpentine belt if it is still relatively new. The Drive notes that replacing the old belt is still a good idea.
Next, locate the alternator in your automobile; refer to the instructions if necessary. The need to raise the car on jack stands may depend on where it is. Regardless, unplug the battery’s negative connector because this repair requires the electrical system.
Once that is finished, detach the serpentine belt from the tensioner located close to the alternator. Next, remove any brackets that are attached to the wiring harness. Install the new alternator after removing the old one. After that, all you need to do is replace everything else and tighten the belt tensioner.
Now, the specific alternator replacement process for your car can include a few extra procedures. According to FCP Euro, some BMWs require you to additionally remove the airbox and a few ducts. The fundamental procedures, however, remain the same: remove the belt from the alternator, replace it, and reinstall it.
What is the turnaround time for an alternator replacement?
It will take a professional roughly two hours to replace an alternator. It could take longer than two hours for a technician to work on your vehicle, so don’t assume that it will just be there for that amount of time. And it will take even longer if the store needs to order parts.
Does AutoZone install alternators?
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.
Should I unplug the battery before changing the alternator?
response given by While the battery must be disconnected from the engine, the battery need not be replaced when the alternator is changed.
What happens if the alternator stops working?
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 might 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 varies 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.
How much does alternator labor cost?
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.
Will a new alternator increase fuel efficiency?
Increased alternator efficiency might result in less power being pulled from the engine, which will improve fuel consumption.
How frequently must an alternator be changed?
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.
