from your overflow valve
To change the radiator overflow bottle on a 2004 Mazda RX-8, first ensure the engine is cool and disconnect the negative battery cable. Remove the hoses connected to the overflow bottle and unscrew any mounting bolts or clips holding it in place. Install the new overflow bottle by reversing the removal process, reconnect the hoses, and refill the coolant as necessary. Finally, reconnect the battery cable and check for leaks.
Check radiator hose, leaking water pump, look for hole in radiator, leaking coolant bottle or leaking seals.
