they had a tendency to overheat in hot conditions, and when stuck in traffic. this is because they need a certain amount of air flowing in order to cool properly.
they also weren’t very good for heat in the winter.
air cooling is a simpler system, and as such has less to go wrong with it. that doesn’t make it better or worse. there are pros and cons to both systems.
VW and Porsche engines area really oil cooled. They have oil cooling radiators inside fan shrouds with thermal expansion baffles that open when it gets hot and close to prevent overcooling in winter.
They didn’t really overheat very often of all the shroud and engine compartment seals were in place and the baffles were in good working order.
The reason you can often go start up an ancient air cooled engine is mainly that they don’t have any water pumps (and water) to sit in them and rust up. That any that there’s no crazy fuel injectors or fancy electrical systems to fail. Just a Carb and distributor to clean/adjust.

Those problems can be easily fixed with aditional fans.
Really strange that it’s so easy but I don’t see any new cars for sale that do it that way
Maybe it’s because air cooling was abandoned a long time ago. All new cars are water cooled.
You’re almost there. Keep going
