If the belt is damaged, loosen the tensioner using the tensioner tool and remove the belt.
Install the new belt following the routing diagram located near the engine bay.
Reconnect the battery.

3. Brake System Inspection and Repair

Tools Required: Jack and jack stands, lug wrench, socket set
Safely lift the vehicle and secure it with jack stands.
Remove the wheel to gain access to the brake components.
Inspect brake pads for excessive wear; replace if they are worn down to the backing plate.
Check for a stuck caliper by attempting to move it; if it sticks, replace it.
Reassemble the wheel, lower the vehicle, and reconnect the battery.

4. Tire Inspection
