Replace the timing belt and pray that you dont have bent valves.

You may have a serpentine belt on that car. I believe they had an electric fan. The serpentine belt is black and you can see it by your alternator, A/C compressor, etc. Under the hood of your car should be sticker on how to route the belt. You can look at that sticker and then see where your belt goes. There is no fan belt on a 1991 Nissan 300zx. The fan is directly driven by an electric motor. The water pump, alternator, and air conditioning compressor are belt driven. The belt for those components is located at the front of the engine.
there should be and idler pulley next to the A/C pump loosen the nut in the center of it do not remove it the pulley will fly off. under the pulley there is a bolt that loosens or tightens up the belt run it all the way up and the belt should come right off
