Ford Mondeo MK3 (2001) Power steering Drive Belt?

Hello, My 2001 Mondeo's power steering belt broke on the way home, I went to get another but had to order it in, have to wait until monday, I drove it back home and I lost power looked at the temp gauge and it was right on the red,Stopped let it cool off.Started again and went to red only when driving, it's ok at idle, I don't see the power steering belt not being on affecting the cooling or am I missing something, again I can't get the belt until monday so thought I would ask here if I might need to replace more parts, Would this be 2 different things I am dealing with now just happened almost at the same time..
Thank you
