87 4kq overheating

[b c]

Yea it is a 50/50 mix.  I use the good anti freeze from the dealer.  That
was my first thought that there is some freezing, which your right is
definately not good.  I'll probably just flush everything out and put new
stuff in.  Would it be possibly for the thermostat to be not working
correctly when it is this cold if its going bad?

Thanks for the help
Ben
