The complexity of the electrical system can also complicate the diagnosis of the issue, leading to extended repair times. In some situations, the complexity of the system may demand specialized tools or expertise, adding even more time to the replacement of the starter.

  1. Type and quality of tools

The type and quality of tools you intend to use also play a role in determining how long it takes to replace a starter.

If the person has all the necessary tools readily available, the task will be completed more efficiently than if they have to stop and gather the tools along the way.

  1. Accessibility

The position of the starter in the car significantly also affects how long it takes to replace a starter. Let’s say the starter is easily accessible, the job can be completed quickly, but supposing it is located in a hard-to-reach area, the process will take a longer period.

How to replace a starter

This step-by-step guide will provide all the information you need to successfully replace a starter.

Step 1: Disconnect the battery

The first step is to disconnect the negative battery cable. This will prevent you from risking electrical shock during the starter replacement process.

Use a socket wrench to loosen the nut and remove the cable. You can also connect an extension cord from your vehicle to provide additional lighting.

Step 2: Locate the starter

Two cylindrical devices are usually attached to the starter, one of which is bigger than the other. The smaller cylinder is the starter solenoid. You can recognize the starter by the connection between the battery and the solenoid.

A wire usually runs from the battery to the solenoid’s terminal, often located at the top of the solenoid. This connection is crucial in finding the starter as it is the primary connection between the battery or fuse box and the starter.

Locating the starter can be difficult as every car is built differently. The best solution is to consult the owner’s manual for your car. If it’s not available, you can search for it on the manufacturer’s website using the model and release year of your car.

Step 3: Remove the starter

Disconnect the wires connected to the starter and use a socket wrench to remove the bolts that hold the starter in place. It is important to keep track of which bolts go where as they may not be the same size.

Step 4: Install the new starter

Place the new starter in the same location as the old one, which may require some adjustments to fit it into the slot properly.

Connect the wires to the appropriate terminals, with the positive wire usually connected to the top terminal and the negative wire connected to the bottom terminal.

Once the wires are connected, secure the starter with the proper-sized bolts and tighten them securely.

Step 5: Reconnect the battery

Reconnect the battery cable by reinstalling the nut and tightening it with a socket wrench. Your starter replacement is complete once the battery connection is secure.

Step 6: Test the car

Start the car and make sure the engine turns over smoothly. If not, pay attention to any sounds it makes. If the car doesn’t start, check the battery and the starter connection to ensure a proper connection is made.

Is it difficult to replace a starter?

Replacing a starter is not a difficult task, but it does require a certain level of mechanical knowledge. The most challenging aspect of the process is often locating the starter, as it can be situated in different positions depending on the make and model of the vehicle.

Once the starter is accessible, the replacement process involves removing the old starter and installing the new one by simply loosening and tightening the bolts. However, supposing you lack the skills or tools to replace the starter, it is advisable to seek the assistance of a professional mechanic.

Without further ado, replacing a starter is not difficult, but it does require some basic mechanical understanding. The most challenging part of the job is often accessing the starter, but once it is located, the rest of the process is relatively straightforward.
