Also check and, if necessary, replace coolant reservoir cap. This is another point of pressure relief.
As far as I know, these two, improper thermostat and/or reservoir cap, are only things that could hold pressure to a point of rad failure.
Pressure relief function you are thinking about may be the bypass feature of the thermostat to relieve coolant pressure at high rev.
