Does my radiator have an engine oil cooler?

Y'all keep calling the radiator's motor oil tank an oil 'cooler' - it's a heat exchanger.
It's actually meant to help motor oil reach minimum operating temp sooner.

However, once the motor oil reaches or exceeds minimum operating temp,
the coolant is actually warmed by the motor oil -
motor oil would be even hotter and coolant cooler if kept separate,
which can also increase oil consumption.
