Am I using the right fan belt - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 1980 350 equiped c20 threw a fan belt and ever since replacing it the belts don't seem to last too long, the altenator and water pump seem to spin fine, the belt I just got is an 11A1145, when I was at the parts store I tried a 13A but it was to wide.
Am I missing something here ?

just a thought, but, have you checked to make sure the pulleys aren't bent? that could cause pre-mature wear.

I checked the pulleys and the bottom ones do have a bit of a wobble in them, I also heard a bit of a clicking noise in that area so I took off the fan belt and the noise is still there , I am thinking of a possible cracked pulley, I'll take them off tomorrow and check them out.

I found the problem !!, The altenator pulley was worn causing the belt to slip when it loaded up Running sweet now

What was the clicking noise you heard? With the belt off , the crank pulley is the only thing turning. Glad you got the problem fixed.

It may have been the power steer pump or belt, it was fairly tight, when I re assembled it the noise was gone
