Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery.

2. Drain CVT Fluid

Locate the CVT fluid drain plug.
Use a socket set to remove the drain plug and allow the fluid to completely drain into a catch pan.
Replace the drain plug securely after draining.

3. Remove Transmission Cover

Remove any necessary underbody panels for access.
Unbolt the transmission cover using a socket set and remove it carefully.

4. Inspect and Replace CVT Belt

Carefully inspect the CVT belt for signs of wear.
If replacement is needed, remove the belt by loosening the tensioner pulley.
Install the new CVT belt by ensuring it is seated correctly on both pulleys.
Adjust the tensioner pulley back into position.

5. Reassemble and Refill CVT Fluid

Replace the transmission cover and secure it with bolts.
Refill with the recommended CVT fluid using a funnel through the fill tube.
Ensure the fluid level is correct according to the manufacturer’s specifications.

6. Final Checks

Reconnect the battery.
Start the engine and allow it to idle for a few minutes, checking for leaks.
Take the vehicle for a test drive to ensure proper operation.
