I have mentioned this product in a few posts but have not lauded its qualities. Nal-Cool for closed cooling systems especialy for you guys running aluminum heads. You should look into it, I have torn down diesels that had many years on them and the inside water parts look like new. It will keep you stuf in good shape 10 times better that anti freeze. Case in point 502EFI closed cooling that rotted the copper coated cross over in the aluminum manifold through and cost $450 to weld and re shape. He now runs Nal-Cool.
