Hi Ed,

For the past 20+ years of Model A Forum questions about Model A engine overheating, everyone appears to be always looking for some inexpensive solution to solve Model A engine overheating problems ...... timing, carburetor jets, brake shoes dragging, low tire pressure, etc., etc., while trying to dodge the cost of professional cleansing of an old clogged radiator, radiator re-coring, or dodge the cost of buying a new Model A radiator.

In most cases, 80+ year old radiators, (and younger radiators), have tubes that are clogged with minerals which cling to the radiator tubes, thus not only reducing rapid water flow, but also not allowing the transfer of heat.

Water from wells or streams in constant contact with the earth are loaded with dissolved minerals which are not filtered even with modern day potable water filtration; hence this type of flowing warm water after many years leaves earth's mineral deposits in Model A radiator tubes.

Constantly using either distilled water and/or rain water can prevent radiator mineral deposits.

To top it all off, recommended 50% antifreeze can prevent old Model A engine rusting where rust particles can easily clog a Model A radiator.

If you would like to try antifreeze in a "clean" radiator one day, we have successfully been using 50% Prestone for over 65 years in vintage tractors and vehicles ........... which in addition, we have noticed Prestone is 100% Snot Free.

Hope this helps someone in the future with 80+ year old Model A engine overheating.
