Beltfed Posted March 27, 2013 Share Posted March 27, 2013 What if anything do you guys run in your coolant systems? I have read that modern antifreeze does not work in these old cars. What say ye. Thanks Link to comment Share on other sites More sharing options...
peecher Posted March 28, 2013 Share Posted March 28, 2013 I use antifreeze in my cars and can't imagine what damage could occur? The good antifreezes have rust inhibitors etc. that are there to protect the cooling system. Link to comment Share on other sites More sharing options...
Beltfed Posted March 28, 2013 Author Share Posted March 28, 2013 The reason I asked was from reading a discussion over on the Buick forum started by 'trp314592' on Nov. 7, 2010. It has a lot to say about organic additive technology vs inorganic additive technology and what these additives do to cooling systems over ten years old. Very interesting reading. If anyone has more information to add please post it. It reminds me of the lack of ZDDP in modern oil problems a couple years back. That problem cost me a fresh 250 Chevy motor. Till then I for one am going to take their advice. Thanks. Link to comment Share on other sites More sharing options...
peecher Posted March 28, 2013 Share Posted March 28, 2013 (edited) There is a good discussion on this at http://www.waynesgarage.com/docs/engine_coolant.htm frequent change-outs are important.

Beltfed Posted March 28, 2013 Author Share Posted March 28, 2013 I read the article from Waynesgarage. I didn't see any mention of really old cars like ours. I do believe that some type of anti-corrosive stuff needs to be in the cooling system as mentioned in the article. I think I will try to find some old style antifreeze to be safe. Thanks.

peecher Posted March 29, 2013 Share Posted March 29, 2013 This might help in your search: From the 1936 Lincoln Zephyr Owner's manual; " Never fail to use an anti-freeze solution in cold weather. Ethylene Glycol. radiator glycerin, or alcohol are recommended as anti-freeze solutions. These are all organic liquids and like water will cause rusting in any system containing iron. This iron rusting can be controlled by the use of a rust inhibiter which can be obtained at Lincoln Zephyr service stations. Ethylene Glycol, some radiator glycerines and some brands of alcohol,as marketed, contain an effective inhibiter to control this corrosion."

DSpringer Posted March 29, 2013 Share Posted March 29, 2013 The same exact language is in the '41 owner's manual. Link to comment Share on other sites More sharing options...
