How to Align the Timing Belt of Citroen c5 Engine

Precisely, there is a timing mark, but pay attention to the mark of the oil pump, and don't forget that there is a balance shaft behind the oil pump.

Maybe the mark is right, but the position of the balance shaft is wrong, which will lead to engine jitter and weakness! On the cylinder block behind the oil pump, there is a rose near the foot. Remove it and turn the oil pump teeth until the rose knife can be inserted.

Check whether the marks of the oil pump are aligned.
