Advice on Chevy Celebrity Eurosport

[jr2712]

I'd like to know if any of you could tell me which of the two cooling fan blade styles is better for the Celebrity: curved or straight blades? I know GM offered a standard cooling system and a heavy-duty one, but I can't remember which one. Thanks in advance.

I think the fan with 5 straight blades is larger diameter and larger motor-i think i have only seen this fan on '85-later 2.8 . The 7 curved blades style i have seen on 2.5 and 2.8. The 4.3 diesel (82-85) had a big 16.5" 7 straight blades with a very big motor-about the most powerful electric fan i have seen on any car I used to salvage these fans to repurpose to other uses. I have only seen copper/brass radiators on Celebrities.
