How to align the timing belt on a Roewe 550?

[Lulu]

Block the timing wheel of the engine with a wheel chock to prevent the wheel from rotating during chain tooth alignment, which could cause alignment failure. Locate the blue timing chain teeth on the engine camshaft. The colored chain teeth are used for timing chain calibration. Align the colored chain on the engine with the small dot on the camshaft to correct the chain teeth. After calibration, use a wrench to clamp the timing shaft so that the calibrated chain teeth can be securely fastened.
