Sorry to hear that, i am not a enginer so all i can tell you is yes it can, once it as thawed out check water leval and see if it as dropped, if water as dropped you could have blown the rad or crack the block or popped a corplug, if water leval is ok then start engine and warm it up keep an eye on water leval and check for leaks anywhere, you may have been looky but its been bloody cold this week, if unsure take it in garage for a pressure check, sorry to be so blunt but i been there many years back, I hope you have not dammaged anything,
