A 50-50 mixture of antifreeze and wayer that 's presurized to about 14 psi won't boil until it reaches a temperature of about 260 degrees.
50-50 % is correct.
Your cap saying "antifreeze only" mean that do not put oil, brake fluid, power steering fluid. BUT antifreeze only and that is 50-50 or according to your book.( 50% antifreeze - 50% plain water)
For the overcooling problem check if the fan is working all the time ( and let me know)
otherwise, remove your thermostat and check it. :)
