Ensure that the engine cylinder can inhale and exhaust normally. The replacement method of the timing chain is: 1. Remove the valve cover, remove the timing chain shell and remove it;2. Turn the crankshaft to the top dead center of a cylinder, and screw the crankshaft fixing screw on to fix the crankshaft;3.

Do not have gaps in the crankshaft position sensor during installation to avoid reporting fault codes.
