What type of antifreeze for Nissan 91 pickup?
I was wondering what type of antifreeze to use in my Nissan 91 pickup. It looks like it has
the yellow/green stuff in there. Is that the propylene glycol? Does that sound right? Also
what is the appropriate mixture for a very cold climate? I live in Alaska and it easily gets
to -30F. Any brands recommended? Does it hurt to mix 2 different coolants?
