01Step 1: Gather the necessary tools and materials

  • To change a car serpentine belt, you will need the following tools and materials:
  • - Wrench or socket set
  • - Belt tensioner tool
  • - Replacement serpentine belt
  • - Safety glasses
  • - Work gloves

02Step 2: Locate the serpentine belt and inspect for damage

  • Before replacing the serpentine belt, locate it in the engine bay. It is a long belt that runs around various pulleys. Inspect the belt for any signs of damage such as cracking or fraying. If the belt is damaged, it should be replaced immediately.
  • Refer to your car's manual or online resources for the specific location of the serpentine belt in your vehicle.

03Step 3: Release the tension on the old belt

  • To remove the old serpentine belt, you will need to release the tension on it. Locate the belt tensioner, which is a spring-loaded component that keeps the belt tight.
  • Use a wrench or belt tensioner tool to rotate the tensioner and release the tension. This will create enough slack to remove the belt.

04Step 4: Remove the old belt

  • Once the tension is released, carefully remove the old serpentine belt from the pulleys. Take note of the belt routing, as you will need to install the new belt following the same pattern.

05Step 5: Install the new belt

  • Take the new serpentine belt and align it with the pulleys according to the belt routing diagram. Make sure it is properly seated on each pulley.
  • Use the wrench or belt tensioner tool to rotate the tensioner again, and slide the new belt onto the last pulley.

06Step 6: Check the belt tension

  • After installing the new belt, check the tension to ensure it is properly tightened. The belt should have a slight give when pressed with moderate pressure.
  • If the tension is too loose or too tight, adjust it accordingly using the tensioner tool.

07Step 7: Double-check the belt installation

  • Before starting the engine, double-check the serpentine belt installation to make sure it is correctly routed around all the pulleys.
  • Ensure that the belt is not twisted or misaligned, as this can cause damage or noise when the engine is running.

08Step 8: Test the new belt

  • Start the engine and let it run for a few minutes. Listen for any unusual noises or vibrations that could indicate a problem with the belt.
  • If everything sounds and feels normal, you have successfully changed the car serpentine belt.
