Overheating -- Corrective measure questions.

Correct or not, it seems the fan would be more efficient if using the curved tip to scoop the air vs allowing it to run off the back of the blade. This appears to be a Chevy fan design. I would agree the fan spacing in the shroud is incorrect. The fan blade should 1/2 inside the shroud and 1/2 outside the shroud.
