How does the air enter the radiator on the Grumman? Are there shrouds or anything to direct all of the air that passes through the grill bars through the radiator?

Is air able to get around the sides, top or bottom of the radiator? If so, perhaps you can fashion something(s) to funnel all of the air through the radiator itself. Any sort of rubber seals on the top or sides of the radiator?
