A worn-out or broken drive belt can lead to engine damage and other costly repairs. Knowing how to replace it can save you time and money in the long run.
Tools and Materials Needed
Before you begin the replacement process, gather the following tools and materials:
– Replacement drive belt

Step-by-Step Guide to Replacing the Drive Belt
1.
Prepare Your Vehicle
Park your vehicle on a flat, level surface and engage the parking brake. Ensure that the engine is cold before you start the repair to avoid burns.
2.
Locate the Drive Belt
Identify the drive belt in your vehicle. It is typically a rubber belt that runs around the engine’s accessories, and it may be visible from the front of the engine.
3.
Remove the Belt Tensioner
Locate the belt tensioner, which is usually a metal bracket with a tensioner arm. Use the appropriate wrench to loosen the tensioner bolt, allowing the belt to be released from the tensioner.
4.
Remove the Old Drive Belt
Grip the belt at one end and pull it off the pulleys. You may need to twist or maneuver the belt to remove it from some of the pulleys.
5.
Install the New Drive Belt
Slide the new belt over the pulleys, making sure it is properly seated. It may be necessary to adjust the belt tensioner to achieve the correct tension.
6.
Check Belt Tension
Use the belt tensioner to adjust the tension of the new belt. The belt should have some resistance when you try to move it, but it should not be too tight or too loose.
7.
Install the Belt Tensioner
Tighten the belt tensioner bolt, and make sure the belt is secure. Double-check the tension and make any necessary adjustments.
8.
Grease the Belt Tensioner
Apply a small amount of grease to the belt tensioner and pulleys to ensure smooth operation.
9.
Lower the Vehicle and Test the Belt
Lower the vehicle and start the engine. Check the belt tension and operation to ensure that it is running smoothly and quietly.
10.
Dispose of the Old Drive Belt
Dispose of the old drive belt properly, as it may contain hazardous materials.
Safety Precautions
When working on your vehicle, always wear safety glasses and gloves to protect yourself from sharp edges and potential injury. Make sure the engine is cold before beginning the repair, and never work under the vehicle without proper jack stands and support.
By following these steps and taking the necessary precautions, you can successfully replace a drive belt yourself. With some practice, you may even find it easier than taking your vehicle to a professional.
