I have been contemplating relocating my radiator. Does the radiator have to stay in a mostly upright position or could it lay down flat? I had the thought of taking the radiator and mounting it under the hood and cutting a hole in the hood to allow air flow and let the fan do its job. Build a grill over the hood to keep out limbs and debris. Just not sure on the operation of the radiator laying flat. Any input smart, dumb, won't work, recommendations.
