1987–1997 Nissan GQ Y60 Patrol Service Manual (P/N 72760)

• Covers Nissan Patrol and Ford Maverick two-door hardtop, four-door station wagon, utility, and cab-and-chassis models with 3.0-liter carbureted gasoline, 4.2-liter carbureted or fuel-injected gasoline, and 4.2-liter diesel inline-six engines.
• Details in-vehicle engine repair and full overhaul work, including engine removal, cylinder-head disassembly, valve service, piston and bearing inspection, oil-pump service, and timing-belt, timing-chain, and timing-gear procedures.
• Provides carburetor diagnosis and overhaul, ECCS fuel-injection testing, ECU on-board diagnosis and trouble-code access, diesel injection-pump and injector service, glow-plug checks, and emissions/vacuum-system troubleshooting.
• Covers four- and five-speed manual-transmission removal, FS5R30A and FS5R50A overhaul, RE4R03A automatic-transmission diagnosis and removal, TX12A transfer-case service, clutch hydraulics, driveshafts, universal joints, locking hubs, and semi- and full-floating rear axles.
• Includes disc- and drum-brake repair, caliper and wheel-cylinder overhaul, hydraulic bleeding, load-sensing valve service, coil- and leaf-spring suspension work, rear stabilizer-release adjustment, steering-gear removal, and power-steering bleeding.
• Supplies year- and system-specific wiring diagrams for starting/charging/ignition, fuel-injected engine control, headlights, heating and air conditioning, power windows and locks, and windshield/rear-glass wipers.

This Haynes repair manual is supplied as a 302-page PDF set divided into 14 section files covering introductory troubleshooting, 12 technical chapters, and a separate index. It is suited to experienced DIY owners and repair technicians who already have safe lifting equipment and the measuring tools needed for drivetrain and engine work; the manual itself directs some specialist operations to properly equipped shops.

The maintenance schedule brings together fluid and filter service, ignition and valve adjustments, driveline lubricant changes, front-hub bearing service, cooling-system care, brake and suspension checks, and timing-belt replacement. Each interval is supported by the relevant inspection or replacement procedure elsewhere in the manual.

Engine, Fuel, and Electrical Coverage

The engine chapters separate the 4.2-liter pushrod gasoline engine, the 3.0-liter gasoline engine, and the 4.2-liter diesel. Coverage goes well beyond tune-up data. It includes compression and vacuum-gauge diagnosis, engine removal and installation, cylinder-head teardown and assembly, crankshaft and bearing checks, piston-ring fitting, cylinder honing, valve service, and initial start-up after overhaul. Component-specific torque tables, wear limits, clearances, lubrication data, and inspection specifications accompany the repair procedures.

Fuel-system content is matched to the actual engine configuration. The carbureted section covers Nikki carburetor diagnosis, adjustment, removal, and overhaul, while the fuel-injected 4.2-liter section addresses the Electronic Combustion Control System, sensors, injectors, fuel-pressure diagnosis, and ECU-controlled operation. Diesel coverage includes the injection pump, injectors, fuel-cut solenoid, preheat control unit, glow-plug relay, and glow plugs. The emissions chapter adds EVAP, EGR, PCV, Spark Control, BCDD, Hot Idle Compensation, catalytic-converter checks, vacuum-hose routing, and ECU trouble-code charts.

Drivetrain, Chassis, and Body Work

The transmission material distinguishes the manual units and provides exploded views, internal disassembly, synchronizer and end-play inspection, reassembly, and special-tool use. Factory tool references include J-26349-3 and J-34328 for transmission assembly, ST38080001 for the semi-floating axle bearing nut, and KV40104600 for the full-floating axle locknut. Automatic-transmission coverage is intentionally narrower: diagnosis, linkage and inhibitor-switch adjustment, seal and mount service, and unit removal/refitting are included, but internal automatic rebuilding is not. The manual also places transfer-case disassembly and overhaul in the properly equipped shop category because of the tools and techniques required.

Build-dependent specifications distinguish transfer-case lubricant requirements before and after October 1991, manual-transmission attachment details before and after October 1994, and brake-booster data before and after August 1995. Cooling and climate-control sections separate early R-12 from later R-134a systems and include rear-air-conditioning configurations where fitted.

Brake repair covers front discs, rear discs or drums, calipers, master and wheel cylinders, the vacuum booster, load-sensing valve, parking brake, hoses, and system bleeding. Suspension chapters differentiate coil-spring hardtop/wagon layouts from the leaf-spring arrangements used on most utility and cab-chassis models. Body coverage is limited to maintenance, minor damage repair, and removable components such as doors, fenders, tailgates, glass, trim, seats, and the instrument panel; major structural collision repair is left to a body shop.

During differential pinion-seal repair, the manual warns against backing off the pinion nut to reduce preload because the bearing spacer may need replacement. During engine assembly, incorrect piston-ring end gap can allow the ring ends to contact and seriously damage the engine. Heavy drivetrain removal, brake work, fuel-system service, and refrigerant handling require proper support, isolation, and workshop safety practices.
