Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to avoid any electrical shorts during the repair.

2. Remove CVT Belt

Tools Required: Socket set, torque wrench, screwdriver set
Remove the underbody cover to access the CVT. Use appropriate screwdrivers and sockets.
Disconnect any electrical connections and sensors attached to the CVT.
Detach the CVT oil cooler lines if necessary, draining fluid into a suitable container.
Remove the transmission case cover bolts and carefully lift the cover off.
Remove the old CVT belt from the pulleys, noting the routing for the new belt.

3. Inspect and Clean

Inspect the pulleys for wear, scoring, or damage.
Clean the pulleys with a degreaser to remove any contaminants.
Check the CVT fluid pump for proper operation and replace if necessary.

4. Install New CVT Belt

Place the new CVT belt on the pulleys, following the noted routing.
Ensure proper alignment and tension of the belt.
Reinstall the transmission case cover, tightening bolts to the manufacturer's torque specifications.
Reconnect the CVT oil cooler lines and any sensors or electrical connections removed earlier.

5. Refill CVT Fluid

Fill the CVT with the manufacturer-recommended fluid type, using a funnel.
Start the engine and allow it to idle; check for leaks around the CVT and ensure fluid circulates properly.

6. Reassemble and Test

Reattach the underbody cover.
Reconnect the battery.
Perform a test drive to ensure proper function and monitor for any slipping or unusual noises.
