Solution

1. Preparation

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

2. Remove Engine Covers

Remove the plastic engine cover (if applicable) using a socket set.
Take off the timing belt cover by unscrewing the bolts holding it in place.

3. Remove the Old Timing Belt

Align the crankshaft and camshaft timing marks to the top dead center (TDC) position.
Loosen the tensioner bolt and remove the tensioner to release the belt tension.
Carefully slide the timing belt off the camshaft and crankshaft pulleys.

4. Inspect Components

Check the condition of the timing belt tensioner and idler pulley. Replace if worn or damaged.
Inspect the water pump for leaks, as it is typically replaced with the timing belt.

5. Install New Timing Belt

Position the new timing belt according to the manufacturer's specifications, ensuring it aligns with the timing marks.
Reinstall the tensioner and tighten it to the manufacturer's torque specifications.
Recheck the belt tension and alignment before proceeding.

6. Reassemble Engine

Reattach the timing belt cover and tighten the bolts securely.
Replace the engine cover.
Reconnect the battery.
