Clutch noise and belt

A while back, someone answered a question about clutch squeal and attributed it to a serpentine belt.

I bought a shop manual and can't find anything about a belt associated with the clutch.

Can someone help?

I don't know if you're serious or not but I ass-U-me you are so... the belt in question isn't associated with the clutch, there are belts on the front of the engine that drive the water pump, alternator, etc.

If these belts are not quite tight enough, they can make a squeal from time to time, usually when the engine is accelerated rapidly and the driven item (alternator, AC Compressor, whatever) can't keep up because the belt is too loose. The belt will then slip on it's pulley's and make a squealing sound.

Since the engine is often accelerated rapidly when starting out, that's why someone might think the noise was associated with the clutch and since sounds seem to travel around in the metal of a car it might very well sound like it's coming from the clutch rather than the front of the engine.

Right, when you let the clutch out it 'torques' the engine (it twists / turns slightly) with the flexibility of the motormounts and could slightly change the tension on the belts. Possibly making enough of a difference on a belt which is a bit out of adjustment. It's an indirect correlation if it happens at all.

It's mostly inertia. Accelerating the engine as you start out can cause the engine to rev up faster than an alternator or AC compressor can accelerate with a loose and slipping belt.

This is easy to test with a warm engine and the car in neutral and the AC (if so equipped) on. Punch the gas a couple of times and see if you hear the squeak.
