KIA Sorento I 2.5 CRI 140 ps 2005: Timing Belt Replacement & Torque Values Inquiry

Hello.
I am preparing to replace the timing belt in my "SYRENCE" (Sorento I) 2005. 2.5 CDRi 140 ps
1. Is it necessary to replace the water pump?
2. I am looking for values of torque moments for particular bolts.
3. If you have it for the head also along with the order of tightening.

Thank you and best regards.

Are you planning a replacement because something is going on with the car? There are chains from what I remember and a water pump on the bar.

The tadpole has about 300,000 on the wardrobe. While replacing the head gasket, the mechanic found loose chain. The chain is noisy and has a large deflection on the tensioner ... (This is according to KIA ser. Normal service page mileage). As for the gasket, it turned out that I had a cooling EGR. I downloaded from Korea or actually from Mexico because they do it there. But after replacing on a cold motor, slightly smoke white and feel glycol. I think you have to pull back the heads as you used to do. What do you think
For this I still have horses to change in camshaft fights. I will just download it from Korea. The Russian company in Seoul within 2 weeks are parts. Originals or Mobis that make for Hundaja and KIA. I ask about the pump whether to replace because I know that it used to be done when replacing the timing. greetings
