Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool completely before starting work.

2. Remove Engine Covers

Remove any plastic engine covers using a socket set.
Maintain organization of screws and components.

3. Access Timing Belt

Remove the accessory drive belts by loosening the tensioner bolts.
Remove the crankshaft pulley using a socket set and breaker bar for leverage.
Remove the timing belt cover bolts and take off the cover to expose the timing belt.

4. Align Engine Timing

Rotate the crankshaft to align the timing marks on the crankshaft and camshaft gears.
Ensure the engine is at Top Dead Center (TDC) on the compression stroke for cylinder #1.

5. Remove Old Timing Belt

Loosen the timing belt tensioner and remove the old timing belt.
Inspect the tensioner and idler pulley for wear; replace if necessary.

6. Install New Timing Belt

Place the new timing belt over the crankshaft and camshaft gears, ensuring proper alignment with timing marks.
Reinstall the tensioner and adjust it to the specified tension using a torque wrench (usually around 10-15 ft-lbs, but check specifications).
