As I recall from tech school many years ago, 100% antifreeze is a no-no.
It is a poor heat transfer fluid, and will seep through gaskets.  67% gives
the lowest freezing point, but 50% is adequate for most uses, and a better
heat tranfer fluid.

If the engine doesn't heat up, too much water is getting past the
thermostat.  The engine should be able to operate at correct tempoerature
(~180F) over a range of ambient temperatures of -40F to +130F or greater.

I'd check the thermostat.
