Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Drain Transmission Fluid

Place a drain pan under the transmission oil pan.
Remove the transmission fluid pan bolts using a socket set and carefully lower the pan to drain the fluid.
Inspect the fluid for metal shavings or burning odor.

3. Remove the CVT Belt

Remove any components obstructing access to the CVT belt (e.g., battery, air intake).
Carefully remove the CVT belt by loosening the tension on the pulleys. Use a belt removal tool if necessary.
Inspect the pulleys for wear or damage.

4. Install New CVT Belt

Install the new CVT belt, ensuring it is seated correctly on both pulleys.
Adjust the tension according to manufacturer specifications.

5. Reassemble and Refill Transmission Fluid

Reinstall the transmission oil pan and secure it with the appropriate torque.
Refill the transmission with the recommended CVT fluid type, ensuring the correct volume is added.
Reconnect the negative battery terminal.

6. Final Checks

Start the engine and let it idle to circulate the new fluid.
Check for any leaks around the oil pan and ensure the transmission operates smoothly.
