Electrical System Charging Starting:
Alternator testing and replacement, starter motor testing and replacement, battery maintenance and specifications.
Body Exterior:
Door panel removal, hood, trunk lid adjustment, bumper replacement, body panel alignment, and basic dent repair techniques.
Body Interior:
Seat removal/installation, dashboard removal, trim panel replacement, and soundproofing.
Routine Maintenance:
Oil and filter changes, air filter replacement, spark plug replacement, fuel filter replacement, coolant flush and replacement, brake fluid flush, drive belt inspection and replacement, battery checks.
Diagnostic Procedures:
Troubleshooting guides for common starting, running, and electrical issues. Check engine light diagnosis (for fuel injected models). Use of diagnostic tools (OBD-I/OBD-II if applicable).
Major Repairs:
Engine overhaul (short block, long block, cylinder head rebuild), transmission rebuild, clutch replacement, suspension component replacement, brake system overhaul.
Adjustment Procedures:
Valve clearance adjustment (if applicable), idle speed adjustment, timing belt tension adjustment, clutch cable adjustment, parking brake adjustment.
Special Tools:
Identification and recommended use of specialized tools for specific repair tasks (e.g., camshaft timing tools, clutch alignment tool).
Torque Specifications:
Comprehensive list of torque values for critical fasteners across all major systems (engine, chassis, body).

Comprehensive, covering everything from basic maintenance to complete engine and transmission overhauls. Suitable for professional mechanics and advanced DIY enthusiasts.
Diagnostic Capabilities:
Includes diagnostic flowcharts, symptom-to-cause tables, and descriptions of sensor and actuator testing procedures.
Wiring Diagrams:
Detailed electrical wiring diagrams for all major vehicle systems, including engine control, lighting, accessories, and power distribution.
Oil Change Interval:
Typically 5,000-7,500 km or 6 months (whichever comes first), depending on driving conditions. Check manual for specific recommendations.
Timing Belt Replacement:
Critical: 60,000-80,000 km or 4-5 years for gasoline engines with timing belts. Diesel engines may have different intervals or use timing chains.
Engine Oil Viscosity:
Commonly 15W-40 or 20W-50 for naturally aspirated gasoline engines, 10W-30 or 10W-40 for diesel. Check manual for precise recommendations based on climate.
Coolant Type:

Transmission Fluid Manual:
API GL-4 gear oil, viscosity typically 75W-90 or 80W-90.
Engine Performance:
Carbon build-up in combustion chambers, worn valve stem seals leading to oil consumption, potential head gasket leaks on high-mileage engines.
Fuel System Reliability:
Clogged fuel injectors (especially with ethanol), failing fuel pumps, faulty idle air control valves on injected models.
Electrical System Weaknesses:
Corrosion on electrical connectors, aging wiring harnesses, alternator or starter motor failures over time.
Suspension Wear:
Worn ball joints, tie rod ends, and bushings due to road conditions. Sagging springs and worn shock absorbers.
Diesel Engine Specifics:
Glow plug issues, injector pump maintenance, potential for head gasket failure on older diesel engines.
