When you are moving the air pressure under the truck is lowered. This pulls air that has blown through the radiator into the engine down and under the truck. My guess is there is enough turbulence in the engine compartment for this to work OK when moving at higher speeds. But, I really don't think it makes much difference for anything other than aging rubber parts. I've traveled through the San Joaquin Valley on a 110 degree day more than once. It didn't harm anything. People in Phoenix commute in that kind of heat. I haven't heard of anything that has come of it other than some loss of power because the air density decreases when it is that hot.
