Solution

1. Preparation

Gather all necessary tools and parts before beginning the replacement process.
Disconnect the negative battery terminal to prevent any electrical shorts during the process.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Remove Underbody Shields

Use a socket set to remove the bolts securing the underbody shields.
Carefully lower the shields and set them aside.

3. Drain CVT Fluid

Place a drain pan under the transmission pan.
Remove the drain plug or the pan itself (if equipped) to allow the CVT fluid to drain completely.
Reinstall the drain plug after draining.

4. Remove the CVT Belt Cover

Locate the CVT belt cover and remove any fasteners using a socket set.
Carefully detach the cover from the transmission housing and set it aside.

5. Replace the CVT Belt

Using a belt removal tool, release tension on the CVT belt.
Slide the belt off the pulleys and remove it from the transmission.
Install the new CVT belt by following the manufacturer's routing diagram, ensuring it is seated properly on the pulleys.

6. Reassemble Components

Reattach the CVT belt cover and secure it with the previously removed fasteners.
Reinstall the underbody shields and secure them with bolts.
Refill the CVT with the specified fluid type as per the manufacturer's recommendations, ensuring the correct level.

7. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and allow it to idle for a few minutes while checking for leaks.
