Moisture out one tail pipe, and a bit in oil. any idea?

Hey Phil, the antifreeze will gel before it actually freezes solid and I've noticed that the interior of my unheated garage does'nt get as cold as the outside. If it's -25 outside, inside my garage will be -15 degC. Also I should mention that freeze plugs are not used to protect the block from cracking cuss of frozen coolant. They're proper name is "core plug" and are used to plug the holes on the sides of the block which are left over from the rods that are used to support the casting mold when the foundry is pouring the molten iron into the casting mold. If the plugs pop out due to the coolant freezing then that's a plus but that's not their job.
I just thought I'd add this explanation so that builders aren't left with the wrong impression to the point that they depend on the plugs to pop.
Also, if you mix your coolant 50% pure antifreeze to 50% water you'll be good till -40 degC.

Hope this helps

Terry
