I noticed that there is a big cover over/above the radiator that appears to be the intake for the combustion air.
Is that so the air is warmer going into the engine? (warmed by the heat of the radiator?)
I thought I heard that cold air combustion burns cleaner = less pollution.
What temperature is best for fuel economy?
Since I have to move this cover to get at and disconnect the belt-driven fan, should I do anything with the air intake while I am at it?
