Go to your local NAPA. They handle a very comparable product.

Nalcool and Nalprep! I haven't heard those names since the 90's. Great stuff. Had some engines torn down and the mechanics said my liners were perfect. The stuff must have really worked. I don't remember WHY we had them taken apart though. LOL. I do not understand why they do not offer coolant treatment/filters for current engines, or am I mistaken. JM

Some of the antifreezes have SCA mixed in it. Wix calls their treatment Wix-Cool. John Deere has a coolant treatment also.

Do older engines, like in our older D2's, etc. need any of these modern antifreezes or additives? I use regular green Prestone @ 50:50. It seems like the cooling systems on these machines were originally designed to run on anything from pond water to alcohol. Growing up in the 60's, I never heard of anyone using diesel specific antifreezes. If they are better or prevent a problem, I'll use them but I always assumed they were only for the more modern diesels.
