I know the coolant gets pumped through the radiator for it to cool off.
But where exactly does this coolant flow around? I have seen the term “water jackets”…
What is the basic design? Some sort of shell?
Are there “doubled walled” cylinder walls that allow for coolant to flow past the walls of the “inner” engine?
This constant stream of “enclosing fluid” then wicks/dissipates heat away from these walls?
