My car is running rough & now it is slowly raising the temp. I think when I checked the water level I got air in the system or maybe it needs a new temperature gauge? Perhaps water pump?

My car makes a loud noise when I hit any kind of bump and I think it may be the hold down nut for the front strut. How can I tell if that is the problem, and if it is, how do I fix it? If I can't, any idea how much it will cost to get it fixed at a shop?
