fan/alternator squeak.. what did I do here?
 

I replaced the coil for my 930. I must have mounted it up a bit to high on the fan shround. I tightened the aftermarket intercooler, started the car, and there was a a "squeak" "squeak" "squeak" high frequency sound from the vicinity.

I saw that I had managed to squish the coil between the shround and intercooler. Silly....

I assumed I deformed the shroud.

I loosened everything up, slid the coil a bit lower in the bracket, and srewed it all back together. Plenty of clearance.

Still get the sqeaking, which is faint, and correlates to the fans rotation...

I don't see that the blades are rubbing...

Any ideas?

Could this have somehow ruined a alternator bearing? Fan rubbing on the back of the housing?

Plan to address this weekend but any preliminary thoughts appreciated...

Ah, in true 930 DIY paranoia, we tend to look for the most devastating cause. Personally, deforming the shroud is most likely not a possibility. Squeaking and fan rubbing would not sound the same anyway.

Could just be coincidence and time for a new belt. Might just for kicks and giggles spray some belt dressing on the belt. Bet that does the trick.

And in case you don't have a can of belt dressing laying around, a bar of soap held against the inside of the belt should temporarily stop the squeaking - if it's indeed the belt.

Thanks for the happy thoughts :). Will work on it this weekend...

CAREFUL!

Just don't go droppin that bar 'o soap within a 200mi radius of Ronknees... his gadar will have him grindin up against you STAT! :eek:

DANGER WILL ROBINSON!!!
