Depth:
Comprehensive (covers everything from basic maintenance to complete engine and transmission overhauls, including electrical diagnostics and body repair).
Diagnostic Capabilities:
Detailed diagnostic procedures, wiring diagrams, and component testing instructions for all major systems.
Oil Change Interval:
Every 3,750 to 7,500 miles (or 6 months) depending on driving conditions and oil used (consult manual for exact recommendation).
Timing Belt Replacement:
Every 60,000 miles or 4 years (critical on the twin-turbo models due to interference engine design; consult manual for specific V6 engine.)
Engine Oil Capacity:
4.8 US quarts (4.5 liters) with filter change for 6G72 V6 (consult manual for precise capacity and oil type, typically 10W-30 or 5W-30).
Coolant Capacity:
Approx. 9.7 US quarts (9.2 liters) for V6 engines (consult manual for specific capacity and coolant type, usually a 50/50 mix of antifreeze and distilled water).
Brake Fluid Type:

Common Problems:
Active Aero system (spoiler motors, hydraulics) failure, ECS issues, timing belt failure (if not replaced at intervals), electrical gremlins in older harnesses, exhaust manifold cracks (especially on turbos), AC system leaks.
Maintenance Considerations:
Due to complexity, especially on VR-4 models, regular meticulous maintenance is key to longevity. Owners should be aware of the specific needs of the AWD/AWS systems and active aero.
