2003 bmw x5 4.4i with dsp pain in the ass for after market

about every 500 miles i have to top off my coolant maybe quart or so to get red stick to come up ... ac much colder when i do this.. alot of water/condensation pours out on ground after i drive while with ac on and park it ... from middle of car not sure why this is.

Oil leak slight leak prolly from valve cover gasket nothing to be concern with

heater valve leaks at clamp but its oil... thought this was a coolant not oil..hose expands a bit i have hose but looks like a pain to change out otehr end is back of motor

any ideas or thought on this
