Side radiator air flow?

Does the fan on a side radiator DP "pull" air IN through the side grille and radiator?
Or does it "push" engine compartment air OUT through the radiator and grille?
Or do different coaches do it differently?

BTW, I have a rear radiator coach and I already know that the fan "pushes" air from the engine compartment OUT through the CAC, the radiator and the rear grille.

Ours pulls air in from the drivers side and blows it across the engine out the passenger side.

One of the main advantages of the side radiator is that is pulling fresh unheated and generally cleaner air through it. Because of the engine heat, a rear radiator needs to be larger to have the same cooling capacity of a side unit.

Every side radiator motorhome I have ever seen pulls the air in from the drivers side. That is why you will sometimes see a scoop on the side of the motorhome to help "catch" the air. If you think of it, If it tried to go the other way, you would be fighting the airflow down the side of the coach.

Our 08 Monaco pulls air in. Sounds like that is the SOP across the board.
