There is no such thing as shock cooling. Its an OWT that began in the 70's decades after the 1000+ HP aircraft did power off dive bombing runs and power off 'overhead' approaches, over and over again - never having problems with this fictitious condition. Why does this myth persist? There is no evidence for it.
