It is prudent to change the water pump when you're going in to do this particular work because the risk of a subsequent failure say 20,000 km later makes it very expensive and cheap insurance against that.

I also think you need to calm down. You're getting good advice here. Take it to a qualified mechanic and get it fixed.

The manual say:
Code 4 Replace timing belt and inspect water pump*5
remark 5 If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under-20°F, -29°C), replace every 60,000 miles (100,000 km).

so I assume you will need to replace the water pump too.

To the author of the post ... respectfully... dude, you got to use google search for a change... DO YOUR HOMEWORK...
I am tired of your spamming on the forum with new threads asking the smallest and most basic questions ever, without providing any details about your attempts to search and find the answers online.

the mechanical coolant pump is driven off the timing belt, it uses the same kit as the petrol-only v6.
The Electrical coolant pump is for the battery charging system only, and should not be replaced unless it has failed.

I spoke with dealership ,
even they are not aware that car have electric water pump, and are unsure if they need to change it, i am in europe and here we have 3 cars like that in whole europe.
in my country we have 2 cars 1 is petrol before face lift and 1 is mine face lift, so not much info.
thats why here is the forum to help and share knowledge. i ordered kit for timing belt, from rock auto rock the boat.
