In the old days cars wore out around 100,000 miles or a little more. People did not change the coolant and sometimes ran straight water in the radiator. It was common for radiators to plug up and overheat engines. In 1969, I returned from a summer trip of around 8,000 miles in a 1957 Chevy. It overheated and quit within 100 miles of home. We removed the radiatior and had it boiled out. Now I change the coolant like manufr recommend.
Indeed. Manufacturers back in the 70's thru early 80's regularly sold vehicles with only distilled water in the radiators. Owners would later flush their systems only to then add regular tap water to the radiator. Not too mention many of the vehicles sold didn't even have recovery bottles. So when on the road if water need to be added guess what was added?
Tap water.
I believe it was sometime in the mid 80's manufacturers got their game together and decided on making coolant use standard practice.
