Engine Mechanical:
Engine diagnostics, disassembly, inspection, repair, and reassembly for all powertrain variants. Includes cylinder head, block, pistons, rings, crankshaft, camshaft, valve train, timing systems, lubrication, and cooling.
Engine Electrical:
Engine control module (ECM) operation, wiring diagrams, sensor diagnostics (crankshaft position, camshaft position, O2 sensors, MAF, MAP, knock sensors), ignition system, starting and charging systems.
Emission Control:
Evaporative emission control (EVAP), catalytic converter operation, EGR system, secondary air injection (if applicable), onboard diagnostics (OBD-II) related to emissions, and troubleshooting emission control faults.
Fuel System:
Fuel pump operation and testing, fuel injectors, fuel pressure regulation, fuel tank and lines, throttle body, fuel filter replacement, and diagnostic procedures for fuel delivery issues.
Clutch System:
If applicable to manual transmission variants (though Intrigue was primarily FWD with automatic). Details clutch disc, pressure plate, release bearing, clutch master cylinder, and hydraulic lines.
Manual Transaxle:
If applicable. Includes internal components, shifting mechanisms, lubrication, and repair procedures. (Note: Intrigue primarily used automatic transmissions).
Automatic Transaxle:
Complete overhaul and repair of the automatic transmission. Includes torque converter, valve body, clutch packs, planetary gear sets, transmission control module (TCM), fluid service, and diagnostics.
Driveshaft Axle:
Front and rear drive axles, CV joints, boots, hub assemblies, and driveshaft components. Includes inspection, replacement, and balancing.
Suspension:
Front and rear suspension components, struts, shock absorbers, control arms, ball joints, bushings, sway bars, springs, and wheel alignment specifications.
Steering:
Power steering system, steering gear, steering column, tie rods, rack and pinion assembly, power steering pump, fluid specifications, and troubleshooting.
Restraint System:
Airbag system diagnostics, SRS module, seat belts, pretensioners, and component locations. Safety precautions for working with SRS systems.
Brake System:
Front and rear brake components (discs, pads, calipers, rotors), ABS system diagnostics, hydraulic lines, master cylinder, brake fluid specifications, parking brake system, and bleeding procedures.
Body Interior Exterior:
Body panel removal and installation, doors, hood, trunk, bumpers, glass, interior trim, seats, dashboard, headliner, weatherstripping, and body sealing.
Body Electrical:
Complete electrical system, including lighting (headlights, taillights, interior), power windows, power locks, mirrors, wipers, horn, instrument cluster, and body control module (BCM) functions.
HVAC:
Heating, ventilation, and air conditioning system components, refrigerant handling, compressor, condenser, evaporator, blower motor, climate control module, and troubleshooting AC performance.
Maintenance:
Oil changes, filter replacements, fluid checks and top-offs, spark plug replacement, air filter replacement, battery service, belt inspection and replacement.
Troubleshooting:
Systematic diagnostic procedures for common and uncommon issues, including symptom-based troubleshooting charts, DTC (Diagnostic Trouble Code) interpretation, and electrical schematic analysis.
Repair:
Detailed step-by-step instructions for component removal, repair, and reinstallation, including torque specifications, special tool requirements, and alignment procedures.
Installation:
Procedures for installing new or replacement parts, including major components like engines, transmissions, suspension parts, and body panels.
Depth:
Expert level. Covers everything from basic scheduled maintenance to complete engine and transmission rebuilds, complex electrical diagnostics, and bodywork repairs.
Oil Change Interval:
Typically 7,500 miles or 6 months, whichever comes first, when using synthetic oil. Conventional oil intervals would be shorter (e.g., 3,000-5,000 miles). Always consult the manual for specific recommendations based on driving conditions.
Transmission Fluid Change:
Recommended every 50,000 to 100,000 miles, or as indicated by the vehicle's 'change transmission fluid' message or the manual's severe service schedule. Fluid and filter changes are critical for longevity.
Spark Plug Replacement:
Typically around 100,000 miles for platinum or iridium tipped spark plugs. The manual will specify the exact interval and recommended plug type (e.g., AC Delco). Front cylinder plug access can be challenging.
Coolant Type:
Typically a 50/50 mix of Dex-Cool coolant (GM's orange extended-life coolant) and distilled water. Capacity around 10-12 quarts. Check manual for exact type and quantity.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid. Manual will specify the exact type required.
Common Problems:
Intake manifold gasket leaks (especially on the 3800 Series II), oil pressure sensor failures, power steering pump leaks, transmission fluid leaks, occasional HVAC blower motor issues, and interior trim wear. The manual will detail diagnosis and repair for these and many other potential issues.
