September 20th, 2019 by

Whenever your car is turned on it uses electrical power. From the stereo, to the lights and many other electrical components, they all rely on your battery for power. As a result, your battery needs to constantly recharge, otherwise your car won’t be able to keep running. Thankfully, there is a device called the alternator.

What does the alternator do?

The alternator is the component in your RAV4 that is responsible for charging your SUV’s battery. It charges your battery as the car runs by using the power that’s already there. When the alternator has a defect the battery might not get charged. As a result, you will not be able to start your car due to a dead battery. This happens because your battery has run out of juice.

How to tell if you have a defective alternator

You can usually tell if you have a defective alternator if you constantly have to get a jump start after you turn off your vehicle. The alternator is usually located in the engine compartment and whenever it malfunctions, the battery warning light will turn on. This is another way to verify the issue.

How the alternator replacement process works

Once all of the testing and verification have been completed and it’s determined that the alternator is the issue, it needs to be fixed. There are a lot of complicated steps involved but we’ll do our best to explain it for you. The first step is critical for working on the alternator and is performed in order to gain access to the alternator.

Disassembling the surrounding parts

The first step is to carefully remove the radiator assembly. Place that to the side and then remove the radiator itself. Next, remove the front wheel on the right hand side (the passenger side) to make room to work.

Remove the engine under the cover of the rear passenger side. Then the front suspension member on that side also needs to be removed. It’s very important to be gentle with these when removing them, otherwise you’ll end up having to buy more parts to replace.

Next, remove the radiator reservoir tank before removing the fennel and the generator V belt. It’s important to keep in mind that this part of the process can be long, so you’ll need to set aside a good amount of time to do it. Assuming you have all of the necessary tools and skills to use them, it generally takes an average of three and a half hours.

Five steps to remove the generator assembly

  1. Disconnect the two wire harness clamps
  2. Remove the terminal cap
  3. Remove the nuts and disconnect the generator connector
  4. Remove the bolt that is in the cylinder block
  5. Finally, remove the two bolts and also remove the generator.

After removing all of these parts, take your new alternator and replace the old one. Then, perform the entire process in reverse and return all of the components back in the reverse order that you removed them. After you finish returning everything to its place, test the alternator and you should be good to go.

What is the cost of having a shop fix it?

The cost of the alternator replaced on the Toyota RAV4 will vary greatly based on where you live. Generally, 2 to 3 hours of labor is priced between $273 to $284. Then there is also the price of the alternator, which runs between $50 and $160. Adding those two up, you could end up with a cost between the low $300s and the low $500s.
