This 1990 Nissan Pathfinder factory service and repair manual is built around this exact model year and trim lineup, so the torque values, wiring diagrams and rebuild procedures inside are the ones Nissan wrote for the 3.0L V6 (VG30E) under your hood, not a generic substitute pulled from a later Pathfinder.

Known issues on the 1990 Pathfinder. Two recalls are on federal record for this model year. The first covers the front seat belt buckle assembly: the red plastic release buttons marked "PRESS" can break, and broken pieces can fall into the buckle assembly and keep it from latching or releasing properly, leaving occupants without adequate crash protection. The second covers the certification labels, which printed incorrect tire inflation pressures and could lead to improper inflation, loss of vehicle control, and an accident. Owners have filed 43 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're inspecting the seat belt buckles, correcting tire pressure to spec, or working through the VG30E's routine service intervals, this manual keeps you on Nissan's own procedure for your specific 1990 Pathfinder.
