1993 Nissan Truck belts

I have a 93 nissan 4 cyl also but mine is 2wd 5 speed. Mine has 2 belts. As your looking at the engine there is one that goes to the right that wraps around the pulley for the alternator, crank shaft and fan. The other one goes off to the left and wraps around the pulley for the ac compressor and the crankshaft. I hope this helps.
