2. Disconnect Battery

Disconnect the negative terminal of the battery to prevent any electrical shorts or accidental starts during repair.

3. Remove Components

Remove any components obstructing access to the timing belt, such as the engine cover, accessories, and front engine mount (if required).
Tools Needed: Socket set for removing bolts.

4. Remove Timing Belt

Loosen the tensioner bolt and remove the timing belt from the camshaft and crankshaft pulleys.
Carefully note the routing of the timing belt for reinstallation.
Torque Specifications: Follow manufacturer specs for tensioner and pulley bolts.

5. Inspect and Replace Components

Inspect the timing belt tensioner and pulleys for wear; replace if necessary.
Clean any debris from the timing belt area before installing the new belt.
Tools Needed: Timing belt tool kit for proper alignment.

6. Install New Timing Belt

Route the new timing belt according to the markings.
Adjust the tensioner to the specified tension and tighten the tensioner bolt to the manufacturer's torque specification.
Reinstall all components removed during the process.

7. Reconnect Battery

Reconnect the negative terminal of the battery.

8. Test Engine

Start the engine and listen for any unusual noises. Ensure the timing belt operates smoothly without any squeaks or squeals.
