Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery.
Raise the vehicle and secure it on jack stands.

2. Drain CVT Fluid

Locate the CVT fluid drain plug and use a socket wrench to remove it.
Allow the fluid to completely drain into a suitable container.
Replace the drain plug and torque it to manufacturer specifications (usually around 25 Nm).

3. Remove CVT Belt Cover

Remove any components obstructing access to the CVT belt cover, such as air intake ducts or engine covers.
Unscrew the CVT belt cover bolts using a socket set.
Carefully remove the cover and set it aside.

4. Inspect and Replace CVT Belt

Examine the CVT belt for signs of wear, such as cracking, fraying, or glazing.
If the belt is damaged, remove it by loosening the tensioner and sliding it off.
Install the new CVT belt, ensuring it is properly aligned on the pulleys.

5. Reassemble and Fill CVT Fluid

Reattach the CVT belt cover and torque the bolts to specifications.
Refill the CVT with the manufacturer-recommended fluid using a funnel.
Start the engine and allow it to idle for a few minutes, checking for leaks.

6. Final Checks

Reconnect the battery.
Test drive the vehicle to ensure proper function and that the slipping issue is resolved.
