Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.
Raise the vehicle using a jack and secure it on jack stands for safety.

2. Remove the Transmission Cover

Tools Required: Socket set, ratchet, torque wrench
Locate and remove the bolts securing the transmission cover.
Carefully lift the cover off and set it aside, ensuring no debris falls into the transmission.

3. Drain the CVT Fluid

Locate the CVT fluid drain plug at the bottom of the transmission.
Tools Required: Drain pan, socket set
Remove the drain plug and allow the fluid to completely drain into the pan.
Replace the drain plug and tighten it to the manufacturer's specified torque.

4. Remove the Old CVT Belt

Locate the tensioner and release the tension to allow access to the CVT belt.
Carefully slide the old CVT belt off the pulleys. Inspect the belt for wear and note the routing for the new belt.

5. Install the New CVT Belt

Parts Required: New CVT belt
Position the new CVT belt onto the driven and driving pulleys, ensuring it is properly seated.
Reapply tension using the tensioner to ensure the belt is tight.

6. Reassemble and Refill CVT Fluid

Reinstall the transmission cover, ensuring all bolts are tightened to the specified torque.
Refill the CVT with new fluid through the designated fill port according to the manufacturer’s specifications.

7. Test the Transmission

Reconnect the battery and start the vehicle.
Allow the engine to reach normal operating temperature.
Shift through all gears to ensure proper operation, and check for any unusual noises or slipping.
