Most people aren’t automotive pros, but you can probably identify the signs of an alternator that’s going bad. Have you noticed that your lights are either too dim or too bright? Is your battery inexplicably dead? Perhaps your car has trouble starting or it stalls out frequently. These are all telltale signs that you may need a new alternator in your car — but what can do you if you aren’t familiar with your car’s engine?
Finding the right alternator is an important task, but it can be overwhelming if you don’t know where to start. One of the easiest ways to determine the right kind of alternator is to look up your vehicle’s year, make, and model or vehicle information number (VIN). This information should reveal the answer with a quick Google search. You can also look at the original equipment manufacturer (OEM) number that’s directly on the alternator and use it to find the right part.
How to Replace an Alternator?
Once you’ve found the right alternator, you’re won half the battle. Now, though, you need to figure out how to replace your malfunctioning unit with your new, working unit. Luckily, it’s often cited as one of the easiest auto repairs you can DIY. The best way to accomplish the task is to start by disconnecting the battery and the wires attached to the alternator. You’ll notice that there is a tension pulley, and you will need to remove its belt.
Next, remove the alternator’s bolts and remove it from the car. To install the new part, you can reverse the removal steps, starting by inserting it into the car and securing the bolts. You can then reattach the belt to the tension pulley and reconnect the alternator wires. Finally, you can reconnect the battery and take your car for a test run. Hopefully all of the signs of a bad alternator will be gone!
Where to Find Alternators?
Where can you find an alternator to replace your broken one? If you’re adventurous, you can swing by a junkyard and hope for the best. You might get lucky and discover the perfect part at a bargain price. You can also source used parts online or at automotive service shops. This offers the advantage of a bargain, too, but the quality of the part isn’t always guaranteed. It’s usually best to get car parts from a reputable seller and buy them new rather than used. Though the allure of a bargain can be tempting, new parts are often still affordable, and they may come with a warranty or guarantee, too.
It should be noted, too, that’s you’re already saving a good amount by installing your new alternator yourself! A shop may charge several hundred dollars for this task, so you’re making a wise investment by getting the part and doing it yourself. When you get your new alternator from a reliable seller, you may be able to get some advice on your DIY replacement endeavor, too, to ensure you get the results you need.
