6.9. Maintenance of the transmission system: Replacement of auxiliary belts

The maintenance of the transmission system is a crucial part of the proper functioning of any vehicle. One of the most important parts of this system is the auxiliary belt. The auxiliary belt, also known as the serpentine belt, is responsible for driving various engine components such as the alternator, water pump, power steering pump and air conditioning compressor.

Auxiliary belt failure or breakage can lead to serious engine failure, resulting in costly and inconvenient repairs. It is therefore essential that the auxiliary belt is serviced and replaced in accordance with the vehicle manufacturer's recommendations.

When to change the auxiliary belt?

Usually, vehicle manufacturers recommend replacing the auxiliary belt between 60,000 and 100,000 kilometers. However, this may vary depending on the vehicle model, vehicle use and driving conditions. It's always a good idea to check your vehicle's owner's manual for specific information on auxiliary belt maintenance.

Also, it is important to be on the lookout for signs that the auxiliary belt may need to be replaced. This includes abnormal engine noises such as squeaking or grinding, problems with the power steering or air conditioning, warning lights on the dashboard, or a decrease in vehicle performance.

How to change the auxiliary belt?

Changing the auxiliary belt is a task that can be performed by a professional mechanic or a do-it-yourself enthusiast with the proper tools and knowledge. Here are the basic steps involved in changing the auxiliary belt:

1. Turn Off Vehicle: Before you begin, make sure your vehicle is turned off and parked on a level surface.
2. Locate the auxiliary belt: The auxiliary belt is located at the front of the engine and is easily identifiable by its serpentine appearance.
3. Remove the old auxiliary belt: To remove the old auxiliary belt, you will need to loosen tension on the belt using a tension wrench. Once the tension has been released, you can remove the engine belt.
4. Install the new auxiliary belt: To install the new belt, follow the belt routing diagram which should be located under the hood of the vehicle. If the diagram is not available, you can find one in your vehicle's owner's manual or online. Make sure the belt is securely seated on all pulleys and adjust the belt tension.
5. Verify installation: After installation, check that the belt is well tensioned and well seated on all pulleys. Start the engine and observe that the belt is working properly. If everything is in order, the job is done.

In summary, the maintenance and replacement of the auxiliary belt are essential for the proper functioning of the vehicle's transmission system. By keeping your auxiliary belt in good condition, you can prevent serious engine problems and ensure your vehicle continues to run efficiently and reliably.
