Loosen the right front wheel lug nuts. Raise the front of the vehicle and support it securely on jackstands, then remove the wheel.

Install the crankshaft pulley alignment bolt (M6 x 18 mm). If it cannot be installed, the crankshaft pulley must be removed and aligned. Repeat the installation procedure until crankshaft pulley alignment is correct. With the crankshaft pulley alignment bolt (M6 x 18 mm) installed, install the camshaft alignment tool and check the position of the camshafts. If the tool cannot be installed, the engine timing must be corrected by repeating the installation procedure. The correct engine timing is achieved when the camshaft alignment tool, timing pin, and the crankshaft pulley alignment bolt tool can be placed simultaneously.
