You may just need some cooling system maintenance. Thermostat, water pump, radiator, fan clutch, flush the system, maybe some new hoses. Have any of those things ever been done?

 

yes all of that is brand new except for the hoses but i will do them 2marow. eather way i want to put this overflow tank on! how do i do it? and is it worth it! picture help alot!

 

You're talking about converting from a closed to open cooling system. I'm not too knowledgable on the subject of doing that (sorry!), so try and do a search on the subject.
