Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Drain CVT Fluid

Locate the CVT fluid drain plug.
Using a socket set, remove the drain plug and allow the fluid to completely drain into a suitable container.
Replace the drain plug and torque it to the manufacturer’s specifications.

3. Remove the Transmission Cover

Remove any components obstructing access to the transmission cover (e.g., air intake or engine covers) using appropriate tools.
Unscrew the bolts securing the transmission cover and carefully remove it to access the CVT components.

4. Inspect and Replace CVT Belt

Remove the old CVT belt by releasing tension from the pulleys.
Inspect the pulleys for wear; replace if necessary.
Install the new CVT belt by following the path indicated in the service manual.
Ensure the belt is properly aligned and tensioned.

5. Reassemble and Refill CVT Fluid

Reattach the transmission cover and secure it with the bolts, adhering to specified torque values.
Refill the CVT with new fluid, using the recommended type as per the manufacturer’s specifications.
Start the vehicle and allow it to idle, then cycle through the gears to circulate the new fluid.
