2000–2005 Dodge Neon Service & Repair Manual (P/N C4256-90954, PL/SRT-4)

• Covers 2004 PL/Neon and SRT-4 service information, with separate engine and transaxle sections, R/T-specific component details, and left- and right-hand-drive procedures where applicable.
• Engine repair coverage includes 2.0L SOHC and 2.4L DOHC removal, cylinder-head service, internal inspection, crankshaft and piston work, and timing-belt installation.
• SRT-4 turbocharger diagnosis addresses underboost, overboost, abnormal noise, and charge-air leaks, alongside turbocharger replacement and intercooler, oil-line, coolant-line, and vacuum-harness service.
• Separate T350, T850, and 40TE transaxle chapters cover teardown, assembly, and adjustment. Hydraulic clutch service, manual-transaxle synchronizers, and automatic-transaxle pressure testing receive dedicated treatment.
• Suspension and driveline procedures include strut disassembly, wheel-bearing replacement, lower-control-arm repair, rear lateral-arm and tension-strut service, and CV-joint boot replacement.
• Brake coverage distinguishes standard and SRT-4 hardware, rear disc and drum arrangements, and Mark 20e ABS. Steering procedures include pump flow and pressure testing and steering-gear replacement.
• Electrical repair information combines system wiring diagrams, connector pin-outs, and harness-location views with DRB III procedures for PCM/SKIM programming, transaxle Quick Learn, and pinion-factor setting.

This 1,652-page PDF extends from scheduled maintenance through major mechanical repair and body service. It is suited to readers with established automotive repair experience and access to workshop equipment; the overhaul and electronic procedures call for press tooling, measuring equipment, and DRB III scan-tool functions.

Lubrication and Suspension Coverage

This service publication outlines fluid types, capacities, and maintenance intervals based on operating conditions. Separate North American, export, and SRT-4 schedules distinguish routine use from severe-duty service. Transaxle information includes fluid-level checks, drain-and-fill procedures, automatic-transaxle service versus overhaul capacities, and the SRT-4/T850 limited-slip additive requirement.

The suspension chapters document the independent MacPherson strut assemblies, including spring seats, upper mounts, bearings, isolators, and dampers. Separate SRT-4 steering-knuckle procedures address its hub and bearing assembly. ACR-specific inspection notes distinguish certain strut components from the standard arrangement.

The manual explains why the original front lower ball joints are sealed for life and warns that attempts to add grease can damage their nonvented seals. Always verify load limits and use appropriately rated jack stands before getting under the vehicle to inspect these suspension parts.

Torque Tables and Alignment Data

Component-specific torque tables cover front strut tower nuts, steering-knuckle fasteners, and ball-joint pinch bolts, plus rear tension-strut frame-rail bolts, lateral-arm crossmember nuts, and hub-bearing retainers. Specifications use metric and SAE units, with additional tightening-angle requirements where specified.

Factory alignment data covers camber, caster, and total toe. Suspension and steering diagnosis charts, curb-height measurement, and adjustment procedures support alignment work. Named equipment includes strut-nut socket/wrench 6864; the illustrated procedures also show spring-compressor and bearing-press setups.

Engine, Turbocharger, and Transaxle Repair

Engine diagnosis includes compression and cylinder-leakage tests, oil-pressure checks, and mechanical fault charts. Internal service extends to valve guides and seats, hydraulic lash adjusters, bearing-clearance measurement, piston-ring fitting, and oil-pump inspection. The high-output R/T receives specific valve-spring and manifold details. The 2.4L chapter adds piston oil jets, oil-cooler service, and balance-shaft timing.

Turbocharger troubleshooting connects symptoms with wastegate, surge-valve, and control-hose faults. It also identifies prolonged overboost as a potential cause of engine damage.

The transaxle sections go beyond removal and replacement. Manual-unit procedures address differential adjustment and geartrain service, with fixture 8487 identified for T850 assembly work. The automatic chapter covers clutch air-pressure tests, valve-body overhaul, clutch-pack clearances, and bearing-preload selection.

Wiring Diagrams and Diagnostic Scope

The PL wiring section occupies 332 pages. Examples include Fuel/Ignition System, Ground Distribution, and Connector Pin-Outs, with separate connector and splice locations for left- and right-hand-drive vehicles. Other technical illustrations include the turbocharger Vacuum Harness Schematic, ABS Mode Hydraulic Circuit, and 4XTE Transaxle Hydraulic Schematics.

Diagnostic coverage includes symptom charts, electrical tests, DTC retrieval, and module setup. Separate diagnostic publications are referenced for certain fault-code troubleshooting procedures; this service manual does not replace every powertrain, chassis, or body diagnostic volume.

HVAC and Body Service

HVAC coverage includes performance testing, refrigerant leak detection, recovery, evacuation, charging, and heater-core replacement. It distinguishes the variable-orifice arrangement on 2.0L left-hand-drive models from expansion-valve systems on 2.4L and right-hand-drive models.

Body repair information includes water-leak and wind-noise diagnosis, plastic-panel repair, glass replacement, and sunroof adjustment. Frame dimensions, body-opening measurements, weld locations, and structural-adhesive and sealer locations support more extensive body work.
