My shop manual calls for glycerine and ethylene glycol or denatured alchol. I should have her up and running for the first time in 5 or 6 years. my truck http://www.picturetrail.com/gallery/view?p=999&gid=9015746&uid=4287994&members=1 | | |

I haven't seen it in 25-30 years. One thing you may want to consider is adding a wetting agent. It breaks down the surface tension of the anti-freeze and water mixture and really does help in cooling. Most of the street rod guys use it with hi-pro engines that make a lot of heat. | | |

At least that’s what the chart at the store said. | | |
#65055 08/30/2006 4:06 PM | Joined: Apr 2006 Posts: 236 'Bolter | | 'Bolter Joined: Apr 2006 Posts: 236 | Standard green antifreeze is ethylene glycol and rust inhibitors. It should work fine at a 50:50 mixture with water. This ratio provides nearly the optimal ly low freeziing point and highest boiling point. (I think the actual optimal mixture is something like 56% ethylene glycol, but there is little difference in the freezing point supression and raising of the boiling point. So, the easy ratio to remember and make, 50:50, is used.)

Standard green ethylene glycol-based antifreeze is fine. Other modern antifreeze such as Organic Acid Technology (which is pink if I recall correctly; used for a while on some Ford products) and orange Dexcool can attack some gasket materials. This is one reason not all coolants are backwards compatable. | | |

Another product that you see alot of these days.. is "HEET", gas-dryer... is also nothing more than denatured alcohol... so instead of paying a couple bucks for HEET at the auto-parts store.... just stop by your local Walgrens/CVS pharmacy.. and pick up a pint of rubbing alcohol for 50 cents.....lol

Old time antifreeze was methanol, also known as wood alcohal.
