You can get an antifreeze tester at Autozone or other parts store for cheap ($3-$5). Best to get one and check to see the mix. If it does freeze it can crack the block or something else. Water expanse when it freezes.

i live in illinois and it was about 0 degrees F. no it was overheating i popped the hood at home and i could hear it was hot. I think it might have frozen because when i re added my coolant my mixture might have been light on coolant so i will drain it and at like 75 coolant 25 water. would 0 degrees freeze the mixture? i know i felt warmth coming out of the t stat and through the upper radiator hose so i think that the t stat is fine if that makes sense.
So I was able to add a third of a gallon of antifreeze to the system. I started the truck up and it is now - 5 degrees f. It was sooo cold it took 6 min for the truck to get to just 150 degrees. The weird thing is at 150 I usually have heat but I didn't. Now the thermostat is rarely me ( 2 months) is it possible for a thermostat to freeze shut especially if I have a low mix of antifreeze?
Couple of things....75/25 provides less protection thatn 50/50 mix. So you need to get the mixture correct.
Yes, the water around the tstat can freeze, but even if stat doe not freez shut, ice prevents water form flowing to it.
