2002 Dodge Caravan & Chrysler Town & Country Factory Service Manual (PN 81-370-02062)

• 4,426-page DaimlerChrysler factory PDF set for 2002 RS/RG Chrysler Town & Country, Dodge Caravan/Grand Caravan, and Chrysler Voyager/Grand Voyager applications. Coverage includes FWD and AWD, short- and long-wheelbase configurations, and left- or right-hand-drive variants where listed. The service manual identifies Publication No. 81-370-02062; the gas powertrain diagnostic volume also covers applicable 2001 vehicles with the 2.4L and 3.3L/3.8L engines.
• Engine repair coverage spans the 2.4L DOHC four-cylinder, 3.3L and 3.8L V6, 3.3L flexible-fuel, and 2.5L common-rail turbo diesel. Factory procedures address engine removal and installation, cylinder-head and valvetrain service, crankshaft and piston inspection, lubrication-system work, timing-belt or timing-chain installation, diesel piston-protrusion checks, turbocharger service, and cooling-system diagnosis.
• Transmission and driveline sections cover the 31TH three-speed automatic, 41TE/AE four-speed electronic automatic, and T850 five-speed manual, plus the AWD power transfer unit, propeller shaft, rear driveline module, front and rear half shafts, and CV joints. The manuals include removal, internal disassembly, inspection, adjustment, reassembly, installation, and operational testing.
• Chassis repair information distinguishes the MacPherson strut front suspension, FWD and AWD rear layouts, and mono-leaf versus multi-leaf rear springs. Procedures cover struts, control arms and bushings, steering knuckles, hubs and bearings, stabilizer bars, the FWD track bar, wheel alignment, base brakes, Teves Mark 20 ABS/traction control, adjustable pedals, and power steering.
• Dedicated body, chassis, gas powertrain, diesel powertrain, and transmission diagnostic volumes provide DRB III fault testing, no-code symptom diagnosis, verification tests, component locations, connector pinouts, and system schematics. Covered systems include PCM/ECM controls, 41TE/AE transmission electronics, airbag and body control functions, HVAC, tire-pressure monitoring, vehicle theft security, power sliding doors, and the power liftgate.
• Factory reference material includes component-specific torque tables, fluid-capacity and approved-fluid data, pressure-test specifications, wear limits, clearances, electrical test values, exploded views, and section views. Listed service equipment includes the DRB III scan tool, Miller Transmission Simulator 8333 with FWD Adapter 8333-1, and Special Tool 8458 for rear hub/bearing removal.

Engines, Transaxles, Suspension, and AWD Driveline

The 2.4L section covers the cylinder head, camshafts, lash adjusters, rocker arms, balance shafts, oil pump, pistons, crankshaft, and timing drive. The 3.3L/3.8L material addresses the cam-in-block valvetrain, lifters, timing chain, intake and exhaust manifolds, and the oiling system. Diesel-specific chapters add common-rail fuel-system diagnosis, cylinder-liner and piston work, camshaft and crankshaft inspection, timing-position locking, timing-belt tensioning, oil cooler and piston cooling jets, and turbocharger removal and cleaning.

Drivetrain coverage is separated by actual hardware rather than treated as one generic transaxle chapter. The 31TH and 41TE/AE sections document their respective clutch, pump, valve-body, planetary, final-drive, differential, sensor, solenoid, and torque-converter work. The T850 chapter covers shift cables, shafts, synchronizers, differential components, teardown, reassembly, and adjustment. AWD owners also get dedicated repair information for the power transfer unit, rear driveline module, viscous coupler, propeller shaft, seals, bearings, and rear half shafts. Chassis chapters separately identify FWD and AWD rear hub, spring, stabilizer, shock, and half-shaft procedures, while wheel-alignment coverage includes camber, caster, toe, thrust angle, curb height, and pre-alignment inspection.

Diagnostic Manuals and Wiring Coverage

The diagnostic books are organized around conditions, possible causes, pinpoint tests, and post-repair verification rather than code definitions alone. The 41TE/AE material includes AutoStick diagnosis, Quick Learn and clutch-volume procedures, pressure-port identification, solenoid-application information, pressure-switch states, and transmission-range-sensor data. Gas powertrain coverage includes PCM, SKIM, and ignition-key programming where applicable; the diesel volume focuses on the 2.5L direct-injection common-rail system and no-start or communication faults.

Representative electrical references include 8W-10 Power Distribution, 8W-31 Transmission Control, 8W-35 Antilock Brakes, 8W-42 Air Conditioning-Heater, 8W-43 Airbag System, and dedicated power sliding-door and power-liftgate schematics. Connector views, splice and ground locations, bus-communication diagnosis, and lab-scope patterns support body-network and circuit-level fault tracing.

Manual-Specific Service Cautions

The suspension section warns against driving a corroded rear hub and bearing from the axle with hammer blows; impact can damage the assembly and lead to noise or early failure, so the manual identifies a dedicated removal method and tool. The cooling chapters also distinguish approved coolant requirements for aluminum engine components and warn that mixing coolant chemistries can sharply reduce corrosion protection.

Airbag, brake, fuel, refrigerant, rotating machinery, and hoisted-vehicle work should be approached with the factory safety precautions, suitable service equipment, and appropriate experience. Use this set as the repair reference; it does not replace safe vehicle support, system isolation, or proper fuel and refrigerant handling.
