Hey gents,
I finally got around to swapping out my stock 5 blade fan for a “plastic” 11 blade. This is on a 95 C2500 with a TBI 350.
For future reference, it fits great. The only thing that kind of sucks is it’s a pain to install because there’s not a gap between the blades for your arm.
It is a little quieter but more or less has a different less monstrous pitch to it. It seems my AC is cooling off at idle much better. My daughter didn’t know I had changed anything and mentioned it felt like the truck was cooling off allot quicker on her first ride with the new blade.
The picture (attached) really shows the difference between the fan blades.
In general though, my fan seems to stay on way too long, even with a brand new “non-heavy duty” fan clutch. I’m not sure why that is and it’s been something I’ve been tracking for about 2 years with several different replacements.
Here’s the link for the fan blade if anyone is interested in doing the same.
