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

2. Remove Components

Tools Required: Socket set, screwdriver set, torque wrench, and timing belt tool kit.
Remove the engine cover by unscrewing any fasteners.
Detach any components obstructing access to the timing belt, such as the alternator, power steering pump, and any related brackets.
