Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, CVT fluid, fluid pump, transmission jack, multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to prevent electrical shorts during the repair.

2. Inspect and Replace CVT Fluid

Remove the transmission drain plug using a socket set.
Allow old CVT fluid to drain completely into a suitable container.
Replace the drain plug and torque it to the manufacturer’s specifications (check the owner’s manual for the exact torque value).
Use a fluid pump to refill the CVT with fresh, manufacturer-recommended CVT fluid until it reaches the correct level.

3. Inspect and Replace CVT Belt

Raise the vehicle using a transmission jack and secure it on jack stands.
Remove the necessary components to access the CVT belt (this may include the undercarriage shield or other protective covers).
Loosen the tensioner and remove the CVT belt from the pulleys.
Inspect the pulleys for any signs of wear or damage; clean if necessary.
Install the new CVT belt around the pulleys, ensuring it is properly aligned.
Reapply tension to the belt and ensure it is secured according to manufacturer specifications.

4. Reassemble and Reconnect

Reinstall any components removed during the belt replacement process.
Reconnect the battery and ensure all electrical connections are secure.
