Engine Fan Directions

[BigHead-GSO]

This is probably a stupid question but I can’t find any good info on the web so here it is. Should the engine fan on a rear engine RV push air away through the radiator or should it pull air in towards the engine through the radiator?

Hello it pushes air through the radiator from the engine to the rear of the coach.
