if I already bought a new radiator , how much would it cost to get it replaced?

What is your question?

I already have bought a radiator for my car , i just need it put in . I also think I may need new fans , Another issue is the wheel steering it jerks on its own when driving. What is that about ? Lastly , My locks go up and down on its own in the car ? Is that and electrical issue and how much would it cost me to get all of this fixed?
