Question about squeaking noise
 
When I push on the gas pedal and reeve the engine at its loudest point I hear a squeaking noise. Then also happens when I gun it, I have a three speed automatic, right before the gear kicks in two second the squeaking starts then stop once I am second, but then once I start to drive up above 55 the squeaking comes back. If I do not gun it or reeve the engine there is no squeaking noise. Any Suggestion? Also, I thought it might be the belts, but shouldn’t the squeak as soon as I start the truck? :chevy:

It is probably your belts. I had the same problem and found out my fan belt was too wide for the alternator pulley ( It didn't fit down inside the pulley groove). I bought a different belt and that solved my problem.

Belts will also squeal when they get dry rotted and brittle.

Make sure the bolt that holds the alternator on the head is not broke.

When I hear mine squel I know the bolt is broke.

Doyou have power steering? If you do, check the hoses. I had the most irritating squeak that I couldn't find for the longest time. Checked all the usual suspects with no luck. It turned out to be the metal collar of the PS hose rubbing on the frame. goodluck Cnut
