nagging problem
I have a naging problem when I turn at slow speeds mostly when cold I get a rubbing sound almost like a playing card in a bike wheel. Checked all my clearences on the wheells all good and it does not do it all the time. Today I am looking for anything I notice the PO put a flexlite fan and spacer on, it is like 1 or 2 centimeters from the shroud on one side. My question is could slow turning be causing some kind of body or frame flex making the fan hit the inside of the shroud? Does this sound possible? Anyway loosened shroud and moved it like 1/4 inch so have like 1/4 inch clearence now hope that was it.
Thanks

Re: nagging problem
That is what my fan sounded like when it was rubbing the stock shroud on the old GMC.
Now, on to that fan... have you seen the damage those blade cause when they come off and slice through the hood? |

Re: nagging problem
another thing to think about on thie subject... if the fan is in fact hitting the shroud, the blades are going to be that much weaker and more prone to scattering.

Re: nagging problem
Yes got it, but back to the question do you think the turning could cause the body to flex in a way to move the shroud closer to the fan? I will change the fan this summer can not do it any sooner sorry.

Re: nagging problem
Could very well be doing it... like I said, my GMC did it.
loose/kerfagled motor mounts loose core support loose shroud loose rad Any of these could cause it. |

Re: nagging problem
I totally understand not havin the cash to do things... and not to beat a dead horse, but if you rev it high on a regular basis, or hold it over 3 grand for freeway trips.... for less than 10 bucks you can get a junk yard piece.

Re: nagging problem
Might want to check the engine mounts too, to make sure it isn't moving causing the fan to hit the shroud. If the fan is hitting the shroud, there should be some marks in there. If you break the shroud, theose can be expensive to replace.
