On What?
Today's oils withstand tremendous temperature ranges. The engine is designed to cool it self by either water cooling or air cooling and also the oil flowing through the engine. If everything is working correctly and clean, the engine shouldn't over heat with the help of the OIL cooling as it was designed. If I was to do anything, I would want an oil heater for the cold winter starts.
Transmission or hydro pumps usually don't have the cooling mechanisms an engine have so therefore sometimes an added cooler is warranted.
