How long does replacing an alternator take?
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. As a result, when you turn the key in the ignition, all you’ll hear is a clicking noise rather than your engine’s purring sound.
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.
For a Toyota Camry, how long does it take to change the alternator?
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.
How does a Toyota Camry alternator get changed?
Instructions
- Take the wiring harness off, then step aside.
- disconnect the battery cable.
- Remove the connector from the alternator’s backside.
- To release the belt, turn the 12 mm bolt under the alternator.
- Remove the 14mm alternator pivot bolt.
- To loosen and remove the alternator, slide it back and forth.
Should I unplug the battery before changing the alternator?
Disconnect the battery first and foremost. Your alternator may have multiple wires or only one, but you can be sure that at least one of them is hot. You risk accidentally grounding a live wire if you don’t unhook the batteries beforehand. This results in a variety of negative consequences, not the least of which is shocking you severely.
Does replacing an alternator require replacing the battery as well?
After installing a new car alternator, one of the first items you should check is your battery. You must disconnect the battery before installing the new alternator, according to any installation manual. Therefore, you must at the very least ensure that you reconnect it.
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 much is a brand-new alternator?
In general, a good alternator should cost between $130 and $250. Professionally reconditioned alternators are available at the low end of the pricing spectrum, while new alternators with higher amp ratings for contemporary automobiles are typically available at the high end.
A Toyota alternator costs what?
To keep your Toyota running smoothly on Hilton Head roads when that happens, you’ll need to get a new alternator. The cost of an alternator Depending on the kind of car you drive, a new alternator will typically cost between $500 and $1,000.
Can a car with a damaged alternator be jumpstarted?
It goes without saying that a broken alternator should be replaced as soon as possible, but what if you can’t, or at least not immediately away, and the damage has left your battery so low that a jump start is required? Is this safe? or can a battery with a malfunctioning alternator even be jumpstarted?
Regardless of how terrible the alternator is, you may jumpstart a car and it will continue to operate for a while if the battery is in decent condition. This is so that the automobile won’t operate only on the battery if the alternator is faulty and not delivering the necessary voltage.
By no means is this advised, but it might be required if you only need to drive a short distance. Jumpstarting is intended to get a flat battery operating, so if you’re doing it, your battery probably has gone fairly low.
A jump-started battery will lose charge much more quickly than one that has been fully charged because the alternator won’t be helping it. Of course, if you are using a lot of electricity for things like heating, phone charging, etc., this could happen faster.
Contrary to popular opinion, the engine will continue to run after the jumper wires are removed until the battery voltage is so low that any electrical systems that are necessary for operation are no longer functional.
How can you identify if the problem is with your battery or alternator?
In its most basic form, starting and operating an engine is a 3-step procedure. The battery first jolts the starter with power. The alternator is then activated when the engine is started. The alternator then charges the battery to end this cycle.
Bypassing the battery’s function and jump-starting your vehicle, you can use the process of elimination to identify the offender. The alternator is probably not keeping your battery charged if the engine starts but soon shuts off. If your automobile can be started and maintained by a jump start, but it won’t restart on its own power, you most likely have a dead battery.
Signs of a bad battery
Look for the following typical signs of a dead battery:
- How bright are the dashboard lights? Check the battery gauge on the dashboard first. Even if the car isn’t moving, the battery ought to be charging. If your dashboard lights are dim, your battery is probably having a problem. Try activating your automatic windows, lights, or windshield wipers. Then, after making sure they are all off, try starting the car again.
- Examine the battery for corrosion. If it still won’t start, thoroughly remove any rust from the battery with a towel before having someone jump-start it. Turn off the car after running the engine for a bit. The alternator is doing its duty of keeping the battery operational while the motor is operating, but the battery isn’t holding a charge after the alternator has stopped if you can’t get it to resume.
- The automobile battery may be out of date. Batteries lose their ability to hold a charge as they get older because the metal within corrodes. Car batteries typically last between three and five years. [4] The battery eventually loses its ability to store enough energy to start the car, regardless of how much power the alternator supplies it with. There are, however, things you may take to prolong the life of your automobile battery.
- The radio is not working. The battery should be able to power your radio, headlights, windshield wipers, and other electronic components when your ignition is turned on. Your battery may not be fully charged if you observe your radio display or headlights flickering or fading.
- Your automobile starts, then stops right away. There are several potential causes for this, but the best place to start is by checking your battery. The battery only has enough voltage to start the automobile, which causes this peculiar issue that normally only occurs on specific vehicles.
- You have a bloated battery. Thanks to the manufacturer’s design, you should be able to tell whether your battery is bloated: You’ll be able to spot bulging in the battery’s housing. This issue arises when a defective voltage regulator causes your alternator to overload the battery.
Signs of a bad alternator
It’s time to take a closer check at the alternator if the procedures above indicate that the battery is functional. There are certain signs of a faulty alternator to watch out for. Learn how to identify a bad alternator12:
- Interior lights are dim. Take note of how bright the interior lights are when the car is operating. The alternator is probably to blame if the dashboard gradually darkens.
- headlights that are too bright or dim. Do you notice how your headlights get brighter as you go faster and get dimmer as you slow down? This frequently results from the alternator failing to keep the battery sufficiently charged.
- gurgling sounds Prior to the issue beginning, did you hear a growling sound? Sometimes, that happens before an alternator breaks down.
- heated wire or burning rubber aroma. Are there any symptoms of an overheated alternator, such as the odor of burnt rubber or hot wires? If so, it has to be replaced.
- Alternator testing To test the alternator, some people would advise starting the engine with the negative battery cable unplugged. This is not a smart idea, though, as it could harm your car’s electrical system and result in more serious issues. Learn how to examine an alternator.
