2003–2005 Dodge Neon SRT4 Factory Service & Repair Manual (P/N 81-699-97094)

• Built for owners and repair shops servicing the 2004 Dodge Neon and SRT-4 (PL), covering standard and high-output 2.0L SOHC engines and the 2.4L DOHC Turbo.
• Covers engine removal, cylinder-head and bottom-end repair, timing-belt installation, and 2.4L balance-shaft timing, plus turbocharger and charge-air-cooler service.
• T350 and T850 manual transaxle overhaul includes shaft disassembly, synchronizer inspection, and differential-bearing adjustment, alongside clutch service and automatic-transaxle hydraulic testing.
• NGC (Next Generation Controller) troubleshooting addresses fuel injection, ignition, turbo boost control, no-start complaints, and the Sentry Key Immobilizer System.
• Separate diagnostic sections cover Teves Mark 20e ABS, airbags, instrument-cluster faults, PCI-bus communication, and power door locks with remote keyless entry.
• Group 8W wiring diagrams, system schematics, component-location views, and PCM C1–C4 and SKIM connector pinouts support electrical fault tracing and repair planning.

Engine, Turbocharger, and Transaxle Repair

Mechanical coverage includes compression and cylinder-leakage testing, valve and seat service, piston fitting, bearing-clearance measurement, and oil-pump inspection. Turbocharger inspection provides shaft end-play and radial-clearance limits. The turbocharger and exhaust manifold are serviced as one assembly.

Driveline procedures distinguish the turbo installation’s equal-length halfshafts and intermediate-shaft assembly from the unequal-length non-turbo layout.

The T850 chapter treats the Quaife ATB differential as a replacement assembly, with separate component service limited to the ring gear and tapered roller bearings. Related procedures cover differential turning-torque adjustment and gearshift-cable setup.

The main service manual contains 40TE automatic-transaxle repair, including internal disassembly and clutch air-pressure tests. The separate Transmission diagnostic manual is devoted to 40/41TE automatics, with Quick Learn, clutch-volume evaluation, and post-repair verification.

NGC Diagnostics, Emissions Monitors, and Programming

The powertrain documentation follows the six-step troubleshooting procedure and explains sequential fuel injection strategies and OBDII/Euro Stage III monitor operation. PCM operating modes include open- and closed-loop control, with separate discussion of non-monitored circuit limitations. Diagnostic routines address stored trouble codes, intermittent faults, and drivability complaints without a code.

The Natural Vacuum Leak Detection (NVLD) section distinguishes passive small-leak tests from intrusive medium- and large-leak testing. Boost-system coverage extends to the wastegate and surge solenoids, plus the throttle inlet pressure sensor and solenoid.

Programming procedures cover replacement PCM and SKIM modules, ignition-key registration, and electronic pinion-factor setup.

Chassis, Body, and Air-Conditioning Coverage

Beyond powertrain work, the set covers strut and wheel-bearing replacement, wheel alignment, power-steering flow and pressure testing, brake bleeding, and SRT-4-specific brake service. Body sections provide opening dimensions, weld and sealer locations, and glass-service procedures.

Air-conditioning chapters distinguish the variable-orifice system on 2.0L left-hand-drive models from the expansion-valve arrangement on 2.4L and right-hand-drive models. Refrigerant recovery, evacuation, charging, and HVAC housing service are included.

Wiring Diagrams, Test Equipment, and Specifications

Named references include Fuel/Ignition System, Bus Communications, Antilock Brakes, and Airbag System diagrams. Connector/Ground/Splice Location views support harness tracing, while 4XTE Transaxle Hydraulic Schematics show the automatic-transaxle circuits.

Sensor and actuator references provide voltage and resistance thresholds, including oxygen-sensor heater and NVLD-solenoid checks. Mechanical chapters supply torque tables, fluid capacities, and wear and clearance specifications.

Diagnostic procedures are written around the DRBIII scan tool, with references to Miller pinout box #8815 and evaporative-system diagnostic kit #6917. Timing procedures identify crankshaft sprocket installer #6792.

The timing section warns that incorrect crankshaft-sprocket depth can damage the belt and engine. Electrical test cautions identify terminal damage and poor pin contact caused by direct PCM connector probing.

Before beginning repair work, follow the manual’s precautions for electrical testing, pressurized fuel, airbag disabling, and vehicle support.

Included Publications and Page Count

The 2,708-page PDF set contains DaimlerChrysler’s 1,771-page service manual and four diagnostic manuals: Gas Powertrain (390 pages), Body (282), Chassis (52), and Transmission (208). A four-page front-matter file and a one-page navigation file complete the seven-file set.
