Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Screwdrivers
- Timing belt tool kit (if available)
- Pliers
- Oil catch pan
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Engine Covers

Use a socket set to remove any plastic engine covers that obstruct access to the timing belt area.
Carefully set aside the removed covers in a safe location.

3. Drain Engine Oil

Place an oil catch pan beneath the oil pan.
Remove the oil drain plug using a socket wrench and allow the engine oil to fully drain.
Replace the drain plug once the oil has drained.

4. Remove the Timing Belt Cover

Remove any bolts securing the timing belt cover using a socket wrench.
Carefully detach the cover, ensuring not to damage any gaskets or seals.

5. Remove the Old Timing Belt

Rotate the crankshaft to align the timing marks on the crankshaft and camshaft sprockets.
Loosen the tensioner bolt and remove the tensioner.
Carefully slide the timing belt off the camshaft and crankshaft sprockets.
Inspect the tensioner and pulleys for wear; replace if necessary.

6. Install the New Timing Belt

Position the new timing belt according to the timing marks on the crankshaft and camshaft.
Install the tensioner and apply the manufacturer's recommended torque.
Manually rotate the crankshaft two full revolutions and recheck the timing marks to ensure correct alignment.

7. Reassemble Components

Replace the timing belt cover and secure it with bolts.
Refill the engine with new oil using the manufacturer-recommended type.
Reattach any engine covers removed earlier.

8. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and listen for any unusual noises. Ensure the engine runs smoothly.
