Tools Required:

Socket set
Torque wrench
Timing belt kit (including belt, tensioner, and idler pulleys)
OBD-II scanner
Engine hoist (if necessary)

2. Remove Components

2.1: Remove the engine cover by unscrewing the bolts and lifting it off.
2.2: Remove the accessory belts by loosening the tensioner pulleys and sliding the belts off.
2.3: Remove the timing belt cover by unscrewing the bolts and gently prying it off.

3. Remove Old Timing Belt

3.1: Align the timing marks on the crankshaft and camshaft to ensure proper timing.
