How many belts are there on the power steering , alternator & fan on a 1965 Chevy Nova 194 6 cylinder with out air?

Could be a 194,230 or a 250 six cylinder engine.

Power steering?

I don't know model year? Is the radiator fan electric or belt driven? If electric look for electrical connector. Your water pump has to be driven by something. If fan is belt driven, some makes and models, that same belt drives the water pump.

I would suspect the water pump, power steering noises are usually grinding sounds. Also if the belts shredded check behind ALL the pulleys for the reinforcing strands from the belts. Basing this on general car problems , not any actual Chevy.

Loosen all items that move to adjust belts and replace all 3 while you are at it.

V-BELT ADJUSTMENT CAUTION
On models equipped with an electric cooling fan, disconnect the negative battery cable or fan motor wiring harness connector before replacing or adjusting drive belts. The fan may come on, under certain circumstances, even though the ignition is OFF. Alternator Drive Belt

1. Position a ruler perpendicular to the drive belt at its longest run. Test the tightness of the belt by pressing it firmly with your thumb. The deflection should not exceed 1?4 in. (6mm).
2. If the deflection exceeds 1?4 in. (6mm), loosen the alternator mounting and adjusting arm bolts.
3. On 1968-72 V8 and 6 cylinder models, use a prytool to move the alternator toward or away from the engine until the proper tension is reached. NOTE: Apply tension to the front of the alternator only. Positioning the prytool against the rear end housing will damage the alternator.
   
4. On 1973 and later V8 models, place a 1 in. (25.4mm) open-end or equivalent wrench on the adjusting arm bolt and pull on the wrench until the proper tension is achieved.
5. Holding the alternator in place, tighten the adjusting arm bolt. Inspect the belt tension. When the belt is properly tensioned, tighten the alternator mounting bolt. Fig. 1: Alternator belt adjustment
   

Power Steering Drive Belt ALL 6-CYLINDER AND 1971-72 V8 MODELS

1. Holding a ruler perpendicular to the drive belt at its longest run, test the tightness of the belt by pressing it firmly with your thumb. The deflection should not exceed 1?4 in. (6mm).
2. To adjust the belt tension, loosen the adjusting and mounting bolts on the front face of the steering pump cover plate (hub side).
3. Using a prytool on the pump hub, move the power steering pump toward or away from the engine until the proper tension is reached. Do not pry against the reservoir as it is relatively soft and easily deformed.
4. Hold the pump in place, tighten the adjusting arm bolt and then inspect the belt tension. When the belt is properly tensioned tighten the mounting bolts.

1973 AND LATER V8 MODELS

1. Position a ruler perpendicular to the drive belt at its longest run. Test the tightness of the belt by pressing it firmly with your thumb. The deflection should be about 1?4 in. (6mm).
2. To adjust the belt tension, loosen the three bolts in the three elongated adjusting slots at the power steering pump attaching bracket.
3. Turn the steering pump drive belt adjusting nut as required until the proper deflection is obtained. Turning the adjusting nut clockwise will increase tension and decrease deflection; counterclockwise will decrease tension and increase deflection.
4. Without disturbing the pump, tighten the three attaching bolts. Fig. 2: Power steering belt adjustment (slider type)
   

Air Conditioning Compressor Drive Belt

1. Position a ruler perpendicular to the drive belt at its longest run. Test the tightness of the belt by pressing it firmly with your thumb. The deflection should not exceed 1?4 in. (6mm).
2. If the engine is equipped with an idler pulley, loosen the idler pulley adjusting boot, insert a prytool between the pulley and the engine (or in the idler pulley adjusting slot), and adjust the tension accordingly. If the engine is not equipped with an idler pulley, the alternator must be moved to adjust, as outlined under Alternator Drive Belt.
3. When the proper tension is reached, tighten the idler pulley adjusting bolt (if so equipped) or the alternator adjusting and mounting bolts. Fig. 3: Air conditioning belt adjustment
   

Thermactor® Air Pump Drive Belt

1. Position a ruler perpendicular to the drive belt at its longest run. Test the tightness of the belt by pressing it firmly with your thumb. The deflection should be about 1?4 in. (6mm).
2. To adjust the belt tension, loosen the adjusting arm bolt slightly. If necessary, also loosen the mounting belt slightly.
3. Using a prytool, pry against the pump rear cover to move the pump toward or away from the engine as necessary. WARNING
   Do not pry against the pump housing itself, as damage to the housing may result.
   
4. Holding the pump in place, tighten the adjusting arm bolt and recheck the tension. When the belt is properly tensioned, tighten the mounting bolt. Fig. 4: Air pump adjustment points
   

Tighten, your need to tighten the power steering belt a lil bit more, not to much to stretch it but just enough to overcome the resistance of the pump

You could have four belt's.
Fan / Power steering
Fan /Alternator
Fan/ A/C
Air Pump

I have an 82 6.2 and I suspect they are the same. The innermost belt runs over the fan to the A/C unit and down under the power steering back to the crank. The middle belt runs over the fan to the power steering. The out side belt runs over the fan to the alternator. Hope this helps.

Park vehicle on level ground.
2. Remove battery from vehicle.
3. Remove air cleaner outlet hose, engine under cover ( right side ) and exhaust pipe # 2 .
4. Disconnect " B " terminal wire and coupler from the Alternator ( Generator ) .
5. Remove Alternator ( Generator ) belt.

6. Remove power steering pump. Do not disconnect hoses.
6. Remove Alternator ( Generator ) cover.
7. Remove Alternator ( Generator ) bracket mounting bolts.
8. Remove Alternator ( Generator ).

Power Steering pump has three bolts- 2 behind the pulley at 12 and 6 o'clock and one bolt on the back.

Once you get the power steering pump out of the way you can remove the last bolt on the alternator

Ok...I did not remove axle or disconnect hoses on power steering...I did unbolt power steering pump and moved off to side.

after that I disconnected sensor on throttle body and very carefully lifted alternator through the top where your air intake assembly would have been at, right next to A.C. refrigerant lines.It takes a minute , you HAVE TO BE CAREFUL NOT TO DAMAGE SENSOR!!

However it is a lot faster that taking off drive shaft and exhaust pipe!

If you go to AutoZone .com they have exploded diagrams of the parts you have to take off and they will show you bolt locations, the power steering pump bolt at 6 o'clock drove me crazy.

P.S. Get a ratcheting 12 mil wrench, it's a life and knuckle saver!!
