Check your belts for tightness or glazed edges. If the belts are loose, tighten them. If the edges are glazed, either break the glaze with a piece of scotch brite or replace the belts if they are worn.
your serpin belt needs replaced
The alternator belt on a 1993 Nissan 300ZX will typically squeal if it has excessive wear or it has become lose. This provides a good opportunity to replace the belt before it complete fails.
A loose belt. Most likely the alternator belt, if it doesn't squeal when you make a sharp turn.
The squeal is a warning device installed on your vehicle telling you that your brake pads are worn out. The light is coming on because you have a problem. Have your braking system inspected ASAP. Do not ignore this or you will end up replacing the rotors and spending more money. You may also end up having an accident due to defective brakes.
If you are sure it is a belt squeal and not a bearing on a pulley that is squealing, you can buy a belt dressing spray at an auto parts store.
A loose, cracked or dry belt.

A loose belt that becomes more noticeable at cold temperatures.
Automatic transmission fluid does not squeal. You have a different problem. Brakes squeal, bearings squeal, and belts squeal. Fluids do not squeal. You had better take your vehicle to a mechanic.
