Hi there,

Check that the pressure cap is holding pressure ok, check for any external coolant leaks with a system pressure test, are the fans coming on when it get hot? have the radiator cleaned & flow tested, if all is ok have a head check done for Co in the cooling system as this will be an indication of a head gasket problem, start here.
