dumb antifreeze question

[NutmegCT]

Winter's here. You checked your one year old antifreeze a couple weeks ago; the Prestone "immerse the needle" gauge shows the protection is -25 degrees Fahrenheit.

Great.

But you heard this morning that next week the temp might go down to -30.

If that happens, does the block crack? or just the coolant turns slushy, or every single coolant hose and passage splits and explodes, or ...?

Thanks.

Just put the car in your living room and keep the heat running...

I think it may be time to move to a warmer climate.......

Amen.

The coolant may slush up. Can you find a way to put a 100W lightbulb under the hood (in a safe place away from gas)? It ~might~ help with a few degrees' wiggle room.

This is not a time to use a CFL!
I'm not talking about the Canadian Football League.
