How do I fix a faulty coolant pump in my Audi A2?

I noticed that my Audi A2's engine was overheating and upon inspection, I found out that the coolant pump is faulty. I'm not sure what the best course of action is. Any tips?

First, make sure to have the necessary tools such as a socket set and a replacement coolant pump. Then, disconnect the battery before starting the repair. It's also a good idea to have a repair manual or online tutorial handy for reference.
