fan cracks

[swamprat]

i am working on a 1994 4.0 ranger today. When I took off the fan off the front of the engine I noticed some small cracks and one that goes all the way through between the blades. Will this thing grenade on me if I put it back on? I have seen some cracks before but been fine.

Mine looks the same and i put it back on and no problems, but use your best judgment. I cant see yours so replace it if you think it needs to be. Better to replace a fan than a fan and a radiator.

These fans are notorious for that. My fan had that so I replaced it. Not even 6 months later the new one is also cracked in the same spots. I don't think it's a big deal, but I may get a free replacement anyway.

I wish I still had the photo of the fan blade that cameoff and went THRU the hood of my truck!!! If you see ANY cracks throw that bad boy away!!
Yes they will grenade and you will NOT like the results...

new fan blades are about $25 so looks like I will replace. didnt realize that they were that cheap. I think I payed about 70 for one about 15 years ago. It broke but didnt come apart, just got out of balance and make alot of racket.
