You need to track down the leak. Also, check for coolant in your oil? If your engine can't pull a vacuum, cooling system, it can't pull coolant from reservoir. Your intake manifold gasket seems to be a common problem for coolant leak.
How hot does the engine get in degrees F? Also, with the parts you replaced, maybe air in the system?
