change serpentine belt 2202 Cav Eco

2002 Ecotec Is there a special way of changing belt, do I have to move anything, unhook, lift or is it a quick change, belt tensioner etc. Have not looked at car yet. On my other car I had to move a motor mount.Also the fan doesnt work, 1 and 2 dont work only 3&4 work.Thankyou
