I will take another look at it when I get home from work today. There was definitely no part number printed on the fan like on the other one. I'll closely examine it for a stamped number.
I took a close look at this fan and on the radiator side below one of the blades is a stamped Pentastar with the numbers 46237 stamped below the Pentastar. The fan measures 17 inches in diameter. Maybe an AC fan?
