Solution

1. Preparation

Gather tools and parts needed for the replacement.
Disconnect the battery to avoid any electrical shorts.
Allow the engine to cool completely before starting work.

2. Remove Engine Covers

Remove the plastic engine cover using a socket set (usually 10mm).
Set aside all bolts and covers in a safe place.

3. Access Timing Belt

Remove any components obstructing access to the timing belt, such as the alternator, power steering pump, or any brackets.
Take note of how components are connected to ensure proper reinstallation.

4. Remove Old Timing Belt

Align the timing marks on the crankshaft and camshaft sprockets for proper positioning.
Loosen the tensioner and remove the old timing belt carefully.
Inspect the tensioner and idler pulleys for wear and replace if necessary.

5. Install New Timing Belt

Place the new timing belt onto the crankshaft and camshaft sprockets, ensuring it is aligned with the timing marks.
Tension the belt according to manufacturer specifications, usually by adjusting the tensioner.
Rotate the engine manually (using a socket on the crankshaft) two full revolutions to ensure proper tension and alignment.

6. Reassemble Components

Reinstall all previously removed components in reverse order.
Replace any other gaskets or seals disturbed during the process.
Reattach the engine cover and secure all bolts.
