Engine Overhaul, Chassis Repair, and Electrical Diagnosis

This selection of workshop procedures highlights the main repair groups. The manual also covers Sentry Key programming and evaporative emissions leak detection.

• Gasoline engine repair: Step-by-step procedures for engine removal and installation, cylinder-head and valvetrain work, short-block inspection and assembly, and valve timing.

• Transaxle and clutch: NV T350 and Getrag 288 teardown and reassembly, clutch and hydraulic release service, and 41TE diagnosis, pressure testing, and overhaul.

• Suspension and driveline: MacPherson struts, steering knuckles, hubs and bearings, lower control arms, stabilizer bars, twist-beam rear axle, CV halfshafts, and front and rear alignment checks.

• Brakes and steering: Base brake diagnosis, front disc and rear disc or drum service, Mark 20e ABS and traction control diagnosis, ABS bleeding, HCU/ICU service, and power steering pump, gear, hose, cooler, and bleeding procedures.

• Electrical troubleshooting: System wiring diagrams, connector pinouts, ground and splice locations, and circuit tests for gasoline, turbo, diesel, left-hand-drive, right-hand-drive, and export configurations.

• Body and climate control: Left- and right-hand-drive HVAC diagnosis and component service, plus doors, liftgate, glass, sunroof, seats, body structure, and water leak and wind noise diagnosis.

The manual is suited to automotive technicians and experienced owners familiar with factory service procedures. The maintenance group covers approved fluids, capacities, fill and check points, service schedules, hoisting, jump-starting, and towing. Internal overhaul and hydraulic diagnosis call for shop equipment and the specified test tools.

Gasoline Overhaul and Diesel Coverage

The gasoline sections cover the 1.6L SOHC, 2.0L DOHC, and naturally aspirated and high-output turbo versions of the 2.4L DOHC. They include compression and cylinder leakage tests, camshaft and valve service, crankshaft and piston work, bearing inspection, oil pump repair, and timing belt or chain procedures. The 2.4L material adds balance-shaft service, turbo-specific oil jets and cooler lines, and turbocharger diagnosis and replacement. The turbocharger section also covers the charge-air cooler, hoses, oil and coolant lines, and wastegate. On the 2.4L DOHC, turning the camshafts independently with the timing belt removed can cause the valves to contact each other.

For the 2.2L turbo diesel, coverage includes lubrication and capacities, clutch hydraulics, the Getrag 288, halfshafts, battery and starting systems, power steering, HVAC, and wiring. Internal engine overhaul coverage is limited to the gasoline engines.

Transaxle Bench Work and Rear Axle Service

The manual transaxle sections detail cases, shafts, synchronizers, differentials, bearings, seals, and shift controls. The 41TE section pairs hydraulic schematics with road tests, clutch air tests, and fluid leak diagnosis. Bench procedures cover the valve body, oil pump, input clutch, planetary geartrain, final drive, solenoid and pressure-switch assembly, and differential preload.

The halfshaft chapter distinguishes the unequal-length shafts on naturally aspirated cars from the equal-length layout with an intermediate shaft on diesel and turbo models. The rear suspension section covers axle pivot bushings, spindles, springs, shocks, and the Watts link. It identifies remover MB991113 and explains how reversing the Watts-link bell crank can cause premature bearing failure.

Wiring and Fault Isolation

The 8W group covers Power Distribution, Bus Communications, Fuel/Ignition, Transmission Control, Antilock Brakes, and Occupant Restraint circuits. Its connector views and splice and ground maps let you follow a circuit from the schematic to the harness and check for opens, shorts, or excessive voltage drop before replacing a component. The electrical tool references include Probing Tool Package 6807 and Terminal Pick Tool Set 6680. Full DRB III fault-code routines are referenced to separate Powertrain, Transmission, and Body Diagnostic Procedures manuals.

Suspension, brake, fuel, cooling, restraint, and drivetrain work can involve vehicle lifting, loaded springs, pressurized fluids, or pyrotechnic components. Follow the factory precautions for supporting the vehicle and isolating the affected system.

Piston Clearance and Clutch Pressure Examples

For the 2.4L DOHC, piston clearance is 0.024–0.057 mm. The measurement point is 14 mm from the bottom of the skirt on the naturally aspirated piston and 22 mm on the turbo piston.

The 41TE reverse and low/reverse clutch pressure specification is 165–235 psi in reverse at 1,500 rpm with the output stationary and fluid at 150–200°F.
