Sorry ! Just realized it is a diesel
You will need a special timing tool set for that engine the tool has timing mark on it

Make sure you get timing tight ! That is a 0
Tolerance engine
The timing mark on crank is on block beside the gear it looks like a triangle the timing mark for cam on the head beside the cam gear same mark the gears will have dots if you are unsure
Do not attempt ! You can cause an expensive engine repair
