Corvette C8 and cold weather storage coolant protection

larryd · Feb 18, 2021

I put mine away on 10 Nov 20 without checking the fluids if they could stand up to the cold.
Would anyone know what level of freeze protection for engine coolant and washer fluid was added for C8`s shipped to Canada ?
I had a C7 in winter storage for 4 years and no issues.
Note matching snow shovel in pic. Cdn Tire red $12.00, Torch Red corvette special shovel (when available) `add-on` $300.00

That's an expensive shovel support there!
Let us know when you find a torch red snow brush.

But seriously I'm sure GM knows about CDN winters. I think I've used the widow washers once with no issues except a little streaking

Antifreeze as a rule is good for at least -40. I have never had windshield washer fluid freeze. Even in an unheated garage the temperature is not nearly as cold as outside...

thks . DEX-COOL extended life engine coolant is used at 40/60 water ratio. That`s -10F or -23C
So nothing to worry about for 5 years. We hit -12C outside in Ontario recently.
Time to buy a hydrometer.
