Spider web cracks on belt pulley? Normal?
I was just looking from the top of the engine bay down at the drive belt area and noticed what looks like spider web cracks all over the edge of the pulley in the picture below. I believe it's the edge of the pulley that the belt does not actually run on. Can anyone verify whether this is normal in their cars? I've included a picture from above, and I also circled in the diagram the part that I think I'm seeing in terms of those spider web cracks.

Top of the belt is not going to tell the full story, you need to see the other side where the ridges are. Any sort of cracking is sign of aging belt.
How old is the belt and where do you live? If its been over 4-5 years and you live in a area that gets winters, you should look at replacing your belt. |

I'll try to help ya… I have an aftermarket intake and it's really hard to see my pulley but, I'm pretty sure you are looking at cracked factory paint/finish. Mine looks very similar.

Thanks so much, I really appreciate it! I feel much better seeing this is likely normal and it's a paint finish cracking as opposed to the pulley itself.
