-6f. Leave the pink antifreeze in or dump it out?

[lrdchaos]

I have the -50 pink antifreeze in my engine at this time. It’s supposed to get to -6 over the weekend. It’s my understanding that the pink stuff will harden, but not expand at that temperature. What do you normally do when it gets that cold, leave it in or dump it out?

Leave it.
