Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Ensure the vehicle is on a level surface and use jack stands for safety.

2. Drain and Replace Transmission Fluid

Locate the transmission drain plug and position a drain pan underneath.
Remove the drain plug and allow fluid to drain completely.
Replace the drain plug and torque to the manufacturer’s specifications (typically around 8-12 ft-lbs).

3. Remove the CVT Belt

Remove any components obstructing access to the CVT belt (e.g., covers, brackets).
Loosen the tensioner pulley using a socket wrench.
Carefully slide the CVT belt off the pulleys, taking note of its routing.

4. Inspect and Replace Components

Inspect the pulleys for wear or damage and replace if necessary.
Check the tensioner pulley for proper function and replace if it shows signs of wear.
Install a new CVT belt, ensuring it is properly routed around the pulleys.

5. Reassemble and Refill Transmission Fluid

Reinstall any components removed during disassembly.
Refill the transmission with fresh CVT fluid, using the type specified by the manufacturer.
Start the engine and allow it to idle for a few minutes, checking for any leaks.
