Orange undiluted antifreeze 1998 Ca mydillac DeVille
I believe 1 gal of undiluted orange antifreeze is enough for 1998 Cadillac DeVille since 2 gals. 50/50 is enough.!
what about the coolant that;s already in the radiator ? is it at the right mix ? a tester is like $3 Coolant gets old and carries contaminates just like oil and should be changed if dirty
If you use undiluted antifreeze make sure you dilute it 50/50 with distilled water only.
