Do bus radiators get the same airflow as a truck radiator?
No, they don’t. A bus radiator is on the side of the coach and the cooling fan has to pull air through it. On a truck, as soon as you get up to 35 MPH, air is pushing its way into it. The front radiator is a far superior design for a truck that works much heavier carrying an average weight of 80,000 lbs., where a bus seldom carries more than 40,000 lbs. The side radiator design for a bus is very adequate for that engine.
