I believe that the squeel in this engine is related to the power steering. I have replaced the belt for the power steering and air conditioner. I used to think it might be related to the air conditioner until this evening when I did some work and started the car. If I turned the wheel while it was not moving, most of the time I would get the squeeling, not always though. This noise usually happens when the car is first started. Sometimes the noise is there without moving anything. This morning when stopped at a light the noise started. I turned off the blower for the heat and the noise stopped. I have added some lucas power steering additive to the fluid also. I did not have the air conditioner on but would notice that the compressor would kick on and off when the setting in the vehicle was to defrost. I am not totally convinced that it is the power steering. What can I do to verify where the noise is generated and if it is the power steering, what is suggested to fix this? I feel that the belt is sufficiently tight. I do not want to over tighten it. As the vehicle is running, there is no vibration in the belt.
