Connectivity Options:
Basic auxiliary inputs on later models or aftermarket head units. No integrated Bluetooth or USB as standard.
Oil Change Interval:
Typically 15,000 km (9,300 miles) or 12 months, whichever comes first (check manual for specific engine/oil type).
Timing Belt Replacement:
For petrol engines with timing belts (e.g., X16XEL, X18XE1), usually every 60,000-90,000 km (37,000-56,000 miles) or 4-6 years. For timing chain engines (some later ECOTEC), intervals are much longer or 'lifetime'.
Engine Oil Type:
API SJ/SL, ACEA A3/B3/B4; viscosity typically 5W-30 or 5W-40 depending on climate and engine. Check manual for specific engine and oil recommendations (e.g., GM-LL-A-025).
Coolant Type:

Common Problems Ignition:
Ignition coil failure (especially early DIS systems), spark plug wear.
Common Problems Engine:
Oil leaks from gaskets and seals, thermostat failure, PCV system blockages leading to oil consumption.
Common Problems Electrical:
Alternator issues, wiring harness faults (particularly corrosion in connectors), central locking problems.
Common Problems Suspension:
Worn suspension bushings (especially front lower control arm), worn ball joints, rear axle beam bushes.
Common Problems Rust:
Rust can be an issue in wheel arches, sills, and around the rear axle on vehicles in humid climates or those not well maintained.
