I have replaced the water pump, thermosate, radiator cap and had the radiator rebuilt. It is still overheating and I am having to put fluid in the reserve tank everyother day. The car runs great. Not missing out not loosing power or no white smoke.

It is either leaking it or burning it.

Start with compression test, if OK then cooling system pressure test.

Normally I would look at waterpump, but losing coolant is not good (except for leaks).

Could be an intake manifold gasket.
