Oil Change Interval:
Typically 10,000-15,000 km (6,000-9,000 miles) or 12 months, whichever comes first. Consult manual for specific engine and oil type.
Timing Belt Replacement:
Crucial at intervals specified by engine variant (e.g., 60,000 km / 4 years for some engines). Failure can cause severe engine damage. Manual is essential for correct interval.
Spark Plug Replacement:
Varies by plug type (e.g., iridium, platinum). Typically 40,000-80,000 km. Manual provides specific recommendations.
Engine Oil Type E G 5W30:
API SG/SH, ACEA A2/A3. Viscosity commonly 5W-30, 10W-40, or 15W-40 depending on ambient temperature and engine. Manual is critical for exact specs.
Coolant Type:
Ethylene glycol based, silicate-free coolant. GM specification (e.g., G11/G12 equivalent). Manual confirms specific type and mix ratio.
Transmission Fluid Manual:
GL-4 gear oil (e.g., SAE 75W-90). Manual specifies exact type and capacity.
Transmission Fluid Automatic:
Dexron-III (or equivalent). Manual specifies exact type and capacity.
Rust Corrosion:
Common in wheel arches, sills, rear suspension mounts, and strut towers due to age and weather exposure.
Suspension Wear:
Bushings, ball joints, and shock absorbers are prone to wear, leading to knocking noises and poor handling.
Electrical Gremlins:
Faulty door lock actuators, window regulators, dashboard warning lights, and sensor issues can occur.
Viscous Coupling Unit Vcu:
On AWD models, the VCU can seize or degrade over time, affecting drivetrain performance and potentially causing damage to the transfer case.
Engine Idle Instability:
Common with 2.0 16V engines (C20XE/X20XEV) due to vacuum leaks, idle control valve issues, or dirty throttle bodies.
Exhaust Manifold Cracking:
The cast iron exhaust manifold on some models can develop cracks, leading to exhaust leaks and ticking noises.
