Solution

1. Preparation

Tools Required: Socket set, torque wrench, OBD-II scanner, timing belt tool kit, flashlight.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down completely.

2. Remove Components

Sub-steps:
1. Remove the engine cover by unscrewing any bolts and lifting it off.
2. Remove any accessories obstructing the timing belt (e.g., alternator, power steering pump).
3. Drain the engine coolant from the radiator if the water pump is being replaced.

3. Replace Timing Belt

Sub-steps:
1. Align the timing marks on the crankshaft and camshaft pulleys to TDC (Top Dead Center).
2. Loosen the tensioner bolt and remove the old timing belt.
3. Inspect and replace the tensioner and idler pulley if worn.
4. Install the new timing belt, ensuring it is properly aligned with timing marks.
5. Re-tension the belt according to manufacturer specifications (typically around 20-25 Nm).

4. Reassemble Components

Sub-steps:
1. Reinstall any accessories removed earlier.
2. Replace the engine cover and secure it with bolts.
3. Refill the engine coolant if drained, using the recommended coolant type.

5. Final Checks

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the engine and listen for any unusual noises.
3. Check for leaks around the timing belt cover and water pump.
