Okay if I park on an incline my radiator wont leak but when i park on a level ground it leaks. when it leaks it doesnt leak a lot its maybe like a few ounces or less. i tried to look for where it is coming from and its close to the drain plug but i dont think it is it because i flushed my system last year and it just now started to leak after about 2 or 3 months. i have 192k on the car with the same radiator is it time to change it?

 

maybe there is a crack in it, when you park on incline takes the fluid off of the crack and on flat puts it back on. not really sure do a dye test.
