The antifreeze solution can freeze if it is too strong or too weak. Yes,
pure antifreeze can freeze. Well, not quite freeze but turn into a slushy
mess. The slush will usually keep things from breaking from ice expansion
but it will not flow. Antifreeze must never be more than 70/30. 50/50 is
good to about -34F.

Subject: Help Anti Freeze Freeze ?

Cold day here in the Burgh, got below 0 last night. This morn'n the van over
heats ? Had some heat from the front heater core, it seamed to all be
flowing and had lots of pressure, could the Anti freeze have frozen if my
mixture was a bit off ? is my block going to crack next ? does any one know
what freezing point of anti freeze is ? Perhaps the Thermostat just got
stuck.

any info on the anti freeze would be appreciated.
