Dodge Vans & Pickup R1500 1997 Repair Manual Collection

The van manual provides vehicle maintenance and repair coverage, while the separate articles add diesel-engine, transmission, and HVAC material. These publications have different applications; the DN chapters, older ATSG material, and parts catalog should not be treated as interchangeable instructions for every vehicle listed.

Coverage limits: The van file is incomplete: its fuel-system sequence omits printed pages 5-7 through 5-14, and its drivetrain sequence omits pages 7-3 through 7-10, including clutch material. The diesel engine article also refers some operations to separate publications and directs internal turbocharger assembly service to an authorized facility.

PDF Search, Bookmarks, and Diagram Detail

Search and navigation: Eight files contain searchable text; the ATSG manual has no embedded text search. The van manual’s OCR contains recognition errors. The DN chapters have topic bookmarks, although some gasoline-engine tool-section targets are incorrect. Navigation in the van and ATSG files uses generic bookmarks; the two Cummins articles, parts catalog, and trouble-code list have none.

Page and wiring detail: Small wiring labels in the van manual require zooming. The checked ATSG electrical diagrams remain readable when enlarged. Several van pages are cropped at the top, with some text missing.

The ZIP contains nine printable PDFs totaling 1,088 pages, including introductory and reference pages. That total includes the van manual’s final blank page and the gasoline-engine file’s separate blank and publisher-notice pages.

Van Repair, Cummins Service, and Transmission Diagnosis

The following selected contents show the main repair areas. Other included topics range from body and trim replacement to transmission parts identification.

• Van maintenance and engines: Tune-up checks, compression testing, engine removal, cooling-system repairs, and cylinder-head and engine-block reconditioning.

• Cummins adjustments: Valve-clearance inspection, injection-pump timing, throttle-linkage calibration, TP-sensor checks, shutdown-solenoid adjustment, and wastegate testing.

• Diesel component repair: Engine and cylinder-head removal, fuel-injection component replacement, timing-gear work, piston grading, and lubrication-system inspection.

• Transmission and transfer cases: Hydraulic pressure tests, clutch and servo air tests, valve-body service, internal assembly procedures, and NV231/NV242 overhaul.

• Electrical diagnosis: Ignition, starting, charging, and engine-control tests, with wiring diagrams, connector information, fault-code tables, and vacuum schematics.

• Brakes and chassis: Disc and drum brake service, RWAL and four-wheel ABS diagnosis, wheel bearings, suspension joints, steering components, and power-steering bleeding.

• Heating and air conditioning: Performance diagnosis, vacuum-control checks, refrigerant recovery and charging procedures, compressor-clutch service, and front/rear unit repairs.

The van manual addresses do-it-yourself maintenance and repair; the diesel and transmission references suit experienced mechanics with the specified measuring tools, while refrigerant work calls for qualified service personnel.

Van Engines, Electrical Faults, and Chassis Work

The van manual combines illustrated component procedures with troubleshooting charts for starting, charging, cooling, steering, and suspension problems. Its electrical sections connect test methods with circuit information, helping the reader distinguish a wiring or supply problem from a failed component before selecting a repair.

Gasoline-engine material distinguishes throttle-body and multi-port injection systems. It covers fuel-pump and injector work, sensor testing, emission-control components, and engine reconditioning, subject to the missing fuel-system pages identified above.

The drivetrain material identifies NP-2500 and AX-15 five-speed manual transmissions. Included automatic-transmission procedures cover the park/neutral switch, extension-housing seal, assembly removal, and linkage adjustment. Rear-axle coverage includes axle shafts, bearings, and seals; the book expressly excludes differential rebuilding.

Cummins Timing, Component Repair, and Overhaul

The diesel engine article ties pump-timing checks to the engine’s CPL and TIMING TDC information. Its timing tables distinguish California/EGR and non-California applications, helping the mechanic select the applicable plunger-lift reference.

Idle and linkage coverage separates automatic- and manual-transmission operating conditions. It includes throttle-lever break-over, ball-stud position, linkage-rod length, binding checks, and scan-tool TP-sensor readings at the Data Link Connector. Fuel-system procedures extend through filter/water-separator priming and low- and high-pressure line bleeding.

Component service: Step-by-step procedures cover the intake-manifold cover and air heater, exhaust manifold, turbocharger removal, intercooler, cylinder head, front timing cover, crankshaft seals, and M/T flywheel ring gear. Valve-train work includes rocker-lever assemblies, push rods, camshaft bearings and gears, tappets, gear housing, and the timing-pin assembly.

Further sections address fuel injectors, injection and transfer pumps, engine-speed and TP sensors, the water pump, thermostat, and oil pan.

Internal engine work: Cylinder-head overhaul includes warpage checks, valve springs and stem seals, thick- and thin-wall guides, integral and service valve seats, valve depth, and seat width. Block work covers piston, rod, and bearing inspection; A/T and M/T piston grading; ring orientation; crankshaft end play; resurfacing marks; oversize machining; and repair sleeves.

The lubrication chapters explain piston-cooling nozzles, gerotor oil-pump inspection and repair, gear-backlash checks, oil-cooler testing, the pressure regulator, and the filter bypass valve.

Application cautions: The two diesel articles present different timing and TP-check information. The engine article also contains conflicting injection-pump drive-gear-nut torque entries, so it does not provide a consistent single value for that fastener.

Transmission removal, clutch work, belt routing, A/C refrigerant service, and computer relearn procedures are cross-referenced rather than fully supplied within the diesel article.

Transmission Diagnosis and Separate Reference Material

The ATSG manual develops A-904T/A-999 diagnosis through hydraulic pressure tests, clutch and servo air tests, electronic lock-up circuit checks, and symptom charts. Its repair material continues into valve-body work, pump and clutch reconditioning, planetary assemblies, bands, and reassembly.

The separate RE transmission chapter adds electronic-governor diagnosis, overdrive electrical checks, hydraulic-flow diagrams, and clutch-pack and overdrive-unit assembly procedures. Its transfer-case sections distinguish the part-time NV231 from the full- and part-time NV242.

The HVAC chapter treats front and rear blower circuits, compressor-clutch diagnosis, vacuum-operated doors, refrigerant leaks, and heater performance. The parts catalog supplies exploded views and component numbers; the three-page trouble-code file supplies code definitions rather than diagnostic test trees.

Tools, Illustrations, and Repair Cautions

Timing-tool callouts include Engine Barring Tool 7471B, Socket 6840, Adapter 6842, and Dial Indicator 6859 with Tip 6843. Pump-gear work identifies Thrust Washer & Bearing Kit 6862 and Puller L-4407A.

Other component procedures specify Crankshaft Seal Installer 8281, Tappet Changing Set 3822513, and Fuel Injector Puller 3823276.

Illustrations include van multi-port engine-control schematics, starting and charging circuits, the Cummins cylinder-head bolt sequence and engine-oiling diagram, ATSG electronic lock-up wiring, and HVAC vacuum circuits. The diesel engine article contains 40 numbered figures credited to Chrysler Corp.

The Cummins cautions explain how an engaged timing pin can break during crankshaft rotation and how drawing the injection pump into place with its mounting nuts can damage the pump or gear housing. Piston grade and head-gasket selection also depend on the resulting block geometry; intercooled and non-intercooled pistons are not interchangeable.

High-pressure diesel fuel can penetrate skin, and several procedures also involve refrigerant recovery, heavy engine lifting, and rotating components. Use the specified safety equipment and service precautions before starting this work.

A Preview of Cummins Sensor and Oil-Pump Specifications

For the diesel engine article’s A/T and EGR-equipped applications, the TP-sensor adjustment section lists 0.8–1.2 volts at idle and 3–4.1 volts at full throttle. These values accompany the scan-tool and linkage checks.

The oil-pump inspection section gives a gear-backlash specification of .003–.015 in (.08–.38 mm), alongside separate gerotor tip, housing, and sealing-plate clearance data.
