Jeep Cherokee, Comanche, and Wagoneer 1984–2001 Repair Manual (P/N 10 1563920867)

This 336-page PDF contains the 1993 Haynes automotive repair manual for 1984–1993 Jeep Cherokee and Comanche gasoline models, with Wagoneer-specific service notes where applicable. Coverage spans 2WD and 4WD vehicles equipped with the 2.5L inline-four, 2.8L V6, or 4.0L inline-six. This is an aftermarket manual rather than a Jeep factory service publication, and it does not cover 1994–2001 vehicles, full-size Grand Wagoneer models, or diesel engines. Written for the home mechanic, it is best suited to an experienced DIY owner comfortable with safe lifting, electrical testing, pullers, torque tools, and precision measurement, with specialist support available for machining and systems the book places outside home repair.

• Engine repair depth: Covers TDC setup; in-vehicle cylinder-head, rocker-arm, valve-spring, timing-chain, camshaft, oil-pump, oil-pan, and seal service; engine removal; compression and oil-pressure diagnosis; block and head inspection; crankshaft, bearings, pistons, rings, and connecting rods; reassembly; and post-overhaul break-in.

• Fuel and engine controls: Distinguishes early Carter YFA four-cylinder carburetion, V6 2SE/E2SE feedback carburetors, 2.5L TBI, and 4.0L MPI. Procedures cover pressure testing, pumps, lines, tanks, injectors, throttle bodies, EGR/PCV/TAC and air-injection systems, V6 CCCS codes, and 1991-and-later self-diagnosis.

• Transmission and transfer-case work: Includes T4, T5, AX4/AX5, and BA10/5 manual-transmission removal, seals, shift components, and exploded views; three- and four-speed automatic diagnosis and adjustment; and Command-Trac NP207/231 plus Selec-Trac NP228/229/242 removal, linkage adjustment, and assembly identification.

• Clutch, axle, brake, and steering service: Addresses hydraulic clutch bleeding and cylinder overhaul, U-joints, driveshafts, front hubs and axle shafts, axle shift-motor testing, pinion seals, disc/drum brakes, master and wheel cylinders, brake bleeding, steering linkage, solid-front-axle suspension, and power-steering bleeding.

• Cooling, HVAC, body, and chassis electrical: Covers radiator, thermostat, water pump, fan clutch, heater core, blower, and A/C component removal; body-panel and glass service; instruments, switches, wipers, and lighting; plus basic checks for cruise control, power windows, and power locks.

• Diagnostic and specification material: Provides 90 symptom-based troubleshooting sections, vehicle and component ID locations, maintenance schedules, torque tables, capacities, inspection and wear limits, engine clearances, pressure tests, ignition and electrical checks, vacuum schematics, exploded views, and representative chassis wiring diagrams.

Year-Sensitive Coverage

The manual separates 1984–1985 carbureted 2.5L engines from 1986-on TBI versions, distinguishes 49-state/Canadian and California V6 carburetor and emissions layouts, and provides 1991-and-later PCM code and sensor checks. It also calls out 1984–1987 versus 1988-on four-cylinder head-gasket and torque requirements and four different V6 rear-main-seal arrangements, helping prevent parts and procedure mix-ups.

Tools and Illustration Detail

Named job-specific tools include J-29114-1/J-29114-2 for 1984 V6 rope-seal work, J-34686 for the later one-piece V6 rear seal, J-23994 for the V6 valve-stem O-ring vacuum check, and J-28509 for the early four-cylinder distributor trigger wheel.

Representative illustrations include the 2.5L rocker-arm-mount exploded view, V6 right-side exhaust-manifold exploded view, AX4/AX5 output-shaft and synchronizer view, NP231 Command-Trac exploded view, 1985–1986 V6 vacuum-hose diagram, and separate Cherokee/Comanche stop/turn/hazard wiring diagrams.

Important Scope Limits

Internal transmission and transfer-case overhaul is not presented as a complete step-by-step rebuild; those sections supply diagnosis, tool requirements, removal and installation coverage, and exploded assembly references. Major automatic-transmission repair and actual ABS diagnosis or repair are referred to equipped specialists. Cylinder-head valve work, cam-bearing replacement, front-hub bearing service, ball-joint replacement, and refrigerant handling likewise require equipment beyond ordinary hand tools.

The wiring section is selective. It covers typical front and rear lighting, headlight-switch, instrument-illumination, wiper, interior-lighting, and ground circuits—not a year-by-year diagram set or full engine-management wiring.

Later serpentine-belt routing is critical: an incorrect path can spin the water pump backward and overheat the engine. During overhaul, cylinder ridges must be removed before piston/rod removal or a piston can break. Fuel pressure must be relieved before injection work, A/C service involves a pressurized refrigerant circuit, and engine, transmission, axle, and brake work requires proper support and normal shop safety practice.
