Safety Restraint:
Occupant restraint systems, including airbags (driver, passenger), seat belts, and related sensors and control modules.
Maintenance:
Scheduled maintenance procedures (oil changes, filter replacements, fluid checks/changes), tune-ups, inspections, lubrication, and preventative maintenance recommendations.
Diagnostics:
Systematic diagnostic procedures for all major vehicle systems, including troubleshooting guides, symptom-based diagnostics, and the use of diagnostic trouble codes (DTCs).
Repair:
Step-by-step repair procedures for virtually all components and systems, from minor adjustments to major overhauls and component replacements.
Overhaul:
Detailed instructions for the complete disassembly, inspection, repair, and reassembly of major components such as engines, transmissions, differentials, and brake systems.
Installation:
Procedures for the installation of new or replacement parts and components, including torque specifications and critical alignment procedures.
Wiring Diagrams:
Extensive electrical wiring diagrams for all vehicle systems, color-coded for ease of use and troubleshooting.
Depth Of Coverage:
Comprehensive, covering basic maintenance, advanced diagnostics, component-level repair, and complete rebuilds. It provides the same level of detail used by dealership technicians.
Oil Change Interval:
Every 3,000 - 7,500 miles or 6 months, depending on oil type and driving conditions (consult manual for specific recommendation based on oil used).
Engine Oil Filter Replacement:
Replace with every oil change. Recommended part numbers vary by engine (e.g., Mopar MO-090 or equivalent).
Air Filter Replacement:
Inspect every 15,000 miles, replace as needed or every 30,000 miles. Recommended part numbers vary by engine.
Spark Plug Replacement:
Intervals vary significantly by engine type (e.g., I4 ~30,000 miles, V6/V8 ~100,000 miles with platinum plugs). Consult manual.
Engine Oil Spec:
SAE 5W-30 or 10W-30 for 2.5L and 3.9L, SAE 5W-30 for 4.7L V8. API classification: SJ or higher. Consult manual for exact viscosity based on temperature.
Coolant Spec:
Ethylene Glycol-based antifreeze/coolant, meeting Chrysler MS-7170 or MS-9769 (depending on year and formulation) for a 50/50 mix with distilled water.
Brake Fluid Spec:
DOT 3 Heavy Duty Brake Fluid.
Power Steering Fluid Spec:
ATF+3 or ATF+4 (check manual for specific recommendation).
Common Problems:
Radiator leaks/failure, transmission issues (especially 42RE solenoid failures), front suspension wear (ball joints, tie rods), occasional starter motor issues, rust on body panels and frame (depending on climate).
4.7L V8 Specific Issues:
Platting of valve seats due to premature wear (in some early production models), occasional issues with the intake manifold gasket.
