Is engines of volvo buses are air cooled?
 

I had seen a fan/blower near the engine, and i didn't see any radiator. Can anyone clear my doubt?

"The engine is installed horizontally with horizontally aligned cylinders, and the radiator is positioned at the side".

Except for a few cars, most modern surface vehiclescome withliquid-cooled engines due to the following reasons:

- Precise control for better engine performance & emissions control.
- Prevention of overheating.
- Vibration attenuation.
- Better cabin climate controllability.
- etc...

Soichiro Honda, the founder of Honda Motor Co., insisted on air-cooled engines while he was still a designer/mechanic and argued with his employees.

Some popular air-cooled engines are cooled by the air & engine oil. Once stuck in a traffic jam, however, the engine is likely to overheat (there may be exceptions, of course).
