Solution

1. Preparation

Tools Required: General hand tools, torque wrench, timing belt removal tool.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down before beginning work.

2. Remove Engine Covers

Remove any plastic engine covers using the appropriate socket or wrench.
Keep screws and fasteners in a labeled container for reassembly.

3. Access the Timing Belt

Remove any components obstructing access to the timing belt, such as the serpentine belt, harmonic balancer, and any brackets.
Use a crankshaft socket to rotate the engine to TDC (Top Dead Center) on cylinder 1.

4. Remove the Timing Belt

Loosen the timing belt tensioner bolt and remove the timing belt.
Check the condition of the tensioner and idler pulleys, replacing them if worn.

5. Install New Timing Belt

Align the timing marks on the crankshaft and camshaft.
Install the new timing belt, ensuring it is properly tensioned according to manufacturer specifications. Generally, a torque of 15-25 Nm should be applied to the tensioner bolt.
Rotate the engine manually several times to ensure proper alignment and tension before finalizing installation.

6. Reassemble Components

Reinstall all removed components in reverse order, ensuring all bolts are torqued to specifications.
Reattach the engine covers and any other accessories removed during service.
