Packard engine coolant

Posted by Phillip Weeks On 2015/2/5 7:08:13

My 1926 Packard tends to overheat particularly on hills. The engine block was extremely dirty and after many cleans and flushes the coolant is now reasonably clear. The running temperature is still quite high. There is a section in the Packard Service manual 1922-1928 about antifreeze solution and glycerine is recommended between 30 and 45% by volume mixed with water. Has anyone tried using glycerine as a coolant /antifreeze? Are there any risks to the motor?
