Antifreeze Testing,
I never thought to test mine in my 2014 4x4 3.5 Eco. Lariat.
This is a good question?
I thought they were all -35 F or colder. regardless where you live.
Mine must be OK. The coldest so far has been -21 degrees F.
I will get mine done tomorrow at my dealer.
Thanks.
I'm ready for some Global warming.
We've had a cold winter so far.
