1997 Jeep Cherokee Sport Service Manual (PN 81-370-7146)

• Coverage and document identity: A 1,724-page PDF of the Chrysler Corporation service manual for the 1997 XJ Cherokee SE, Sport, and Country in 2-door or 4-door body styles, with 2WD/4WD and LHD/RHD configurations. Main engine coverage is the 2.5L four-cylinder and 4.0L six-cylinder MPI gasoline engines; the PDF also incorporates 2.5L turbo-diesel supplement sections.
• Engine, clutch, cooling, and powertrain repair: Covers gasoline-engine diagnosis and internal repair, cooling-system service, clutch diagnosis and repair, AX5 and AX15 manual transmissions, 30RH and AW4 automatic transmissions, and NV231/NV242 transfer cases. Procedures extend through removal, teardown, inspection, reassembly, adjustment, and operational testing.
• Driveline and chassis work: Details the 181 FBI front axle, 194 RBI and 8¼ rear axles, standard and Trac-Lok differential repair, and propeller-shaft and Cardan-joint service. Steering, wheel-alignment, front link/coil, and rear leaf-spring sections cover diagnosis, removal, installation, and adjustment.
• Fuel and engine-management diagnosis: Combines fuel-pump pressure, capacity, leak-down, and amperage testing with pump-module, tank, quick-connect, and 2.5L/4.0L injector-rail service. PCM input/output checks and component tests address the MAP, TPS, oxygen, coolant-temperature, and intake-air-temperature sensors.
• Brake, HVAC, frame, and body service: Addresses base brakes and all-wheel ABS diagnosis and bleeding, HCU/CAB and wheel-speed-sensor service, R-134a recovery/evacuation/charging and performance testing, heater-A/C housing repair, bumpers, tow hooks, skid plates, trailer hitch, doors, liftgate, glass, seats, and welded-panel replacement.
• Vehicle electrical systems: Covers battery, starting, charging, and ignition diagnosis and repair. Separate sections address the instrument panel, wiper/washer, lighting, airbag, heated glass, power door locks, power windows, power seats, power mirrors, and speed control.
• Wiring and factory reference data: Provides Power Distribution and Junction Block, Fuel/Ignition, Transmission Control, All-Wheel ABS, and A/C/Heater schematics, with gasoline and diesel variations where applicable. Connector pin-outs and connector, ground, and splice-location views support fault tracing. Related sections supply torque tables, fluid capacities, frame dimensions, clearances, wear limits, alignment data, electrical test values, and special-tool listings.

Maintenance, Engine, and Drivetrain Coverage

The maintenance section separates Schedule A normal service from Schedule B severe-duty use, including frequent short trips, dusty operation, trailer towing, extended idling, hot-weather driving, and off-road use. Beyond oil and filter changes, the schedules track spark plugs, ignition cables, drive belts, coolant, transmission and transfer-case fluids, axle lubricants, brake inspections, and steering-linkage and ball-joint lubrication. Fluid data covers the transmissions, transfer cases, front and rear axle families, cooling systems, and power steering fill and bleed work.

The 2.5L and 4.0L gasoline-engine chapters include compression and cylinder-leakage diagnosis, head-gasket and intake-leak checks, oil-pressure testing, cylinder-head and valvetrain repair, camshaft and timing work, piston and ring fitting, crankshaft and connecting-rod bearing service, oil-pump inspection, engine removal, and final assembly specifications. Separate cooling and clutch groups add pressure/leak testing, radiator and water-pump service, and clutch contamination/runout checks. Repair coverage extends to the clutch cover, disc, flywheel, pilot and release bearings, and hydraulic linkage.

Transmission chapters provide road, stall, hydraulic-pressure, time-lag, cooler-flow, and solenoid testing where applicable, followed by internal clutch, geartrain, valve-body, pump, shaft, seal, and linkage repair. Axle sections add pinion-depth setup, differential-bearing preload, backlash, contact-pattern analysis, and Trac-Lok service.

The integrated 2.5L turbo-diesel material covers dedicated maintenance schedules, LHD/RHD turbocharger and exhaust service, fuel-injection pump timing, injector and high-pressure-line work, fuel-system air bleeding, fuel filter/water separator and fuel-heater service, glow-plug and engine-control diagnosis, plus related wiring. It does not add a complete internal diesel-engine overhaul chapter; the full engine teardown and rebuild sections in this PDF apply to the 2.5L and 4.0L gasoline engines.

Diagnostics, Special Tools, and Service Limits

Fuel-system diagnosis links tests so pump output, residual-pressure loss, regulator/check-valve faults, injector leakage, and current draw can be separated before parts are replaced. The manual also covers ASD and fuel-pump relay tests, throttle-body minimum-air-flow checks, sensor resistance/voltage checks, PCM connector cavities, and DRB-assisted procedures. Named equipment includes Fuel Pressure Gauge Set 5069, fuel-line adapters 6539 and 6631, fuel-pump-module locknut Tool 6856, fixed-orifice Tool 6714, driveline Inclinometer 7663, timing-cover alignment/seal Tool 6139, and rear-main-seal installer 6271A.

Two XJ-specific repair traps are stated clearly. The fuel-pump module must be indexed correctly so the sender float rod cannot contact the tank, while rubber-bushed suspension fasteners must be tightened at normal ride height to prevent altered ride quality and premature bushing wear. The fuel system remains pressurized with the engine off, and the lifting section identifies the correct frame-rail and subframe-rail contact points while warning that removing drivetrain or chassis components changes the vehicle’s center of gravity.
