Hey there folks! How is everyone doing? Long time since I last annoyed you all.

How much coolant for my 81? I do have an after market aluminum radiator so If anyone has made that change it would be helpful. If memory serves me I thought it was 5 gallons but I could be confusing it with a bunch of other vehicles because, well, memory does not serve me.

My best to all,

Dave

yeah, I know, shut up Dave

I think that's a tad much. 18 quarts is in my mind. That's total!
