Keeping coolant and transmission temps under control when towing in the summer heat

Is there a 5 blade rimmed, or was that only the 7 blade model?

I don’t believe that any of the 5 blade fans have rims.

I have seen some pictures of 5 blade rimmed on ebay

I pulled this rimmed 5/7 set off a 2005 last year.

Thank you for confirming my illusion confusions. I thought they had both models.
So now there’s a triple threat monkey wrench added to the mix. Which one is better?
I’m also wondering if the engine size plays a role in how well the fan works (i.e. will a 5/5 rimless work better for the 6.2l, whereas the 5/5 rimmed is better for the 5.3l?)

Are there only two bolts holding that fan shroud on? If so I can zip them off real quick and get you guys the numbers and photos from my Denali.

Doing a cfm test will have to wait until I have her back together though. Currently she has no fluids or a front end.

If you're asking me about the 2005 fans I posted, the answer is yes. The bottom of the shroud has tabs that insert at the bottom, with the two bolts on the top part.

Do you have the K5L rpo?

Huh. Good to know!

I don't think the 5 blade rimmed was a 700w option only 500w but I could be wrong
