Im adding coolant every 2wks, I could not trace any leaks anywhere and I changed the reservoir cap. What should I do next?

Have you checked along the intake? Also, check the motor oil to make sure no coolant is getting into the engine as well as check the radiator (when the engine is cold) to make sure no oil is getting into it.

Let me know what you find.

PS: The intake gaskets are pron to leak. Check closely. You may want to pressure test the cooling system. Also, they make a dye to add to the coolant. Drive it, then using a black light, check for leaks. If the dye is present, it should glow.
