I find it ironic that in a thread for the ERGO cab, we see the Chrysler Airflow.
As a kid in the 50’s our family car was a 35 straight 8 Airflow.
It too had a crankshaft driven fan and yes it also had overheating problems.
Not designed for our dreadful Aus. “roads” and a good rough bumpy road would shake the engine on its mounts and have the fan into the radiator core.
