Help finding an old thread

[Hopfan]

I read a thread some time ago, (thought I saved it, but I'm a *******) about how to find the refrigerant lines in a fridge using (baking soda???). I have been searching for over an hour and can't find it. Can anyone help me out?

I'm thinking of buying a fridge w/o freezer at Sears and I want to be sure of where I can drill.

Thanks
