Engine Layout:
Inline-4 (I4) and V6 configurations
Valvetrain:
SOHC or DOHC, typically with 4 valves per cylinder.
Engine Oil Change:
Typically every 7,500 to 10,000 miles (12,000 to 16,000 km) or 12 months, depending on driving conditions and oil specification.
Timing Belt Replacement:
For 2.4L and 2.8L V6 engines, recommended replacement interval is typically 70,000 to 100,000 miles (112,000 to 160,000 km) or 5-7 years. Inline-4 engines may have timing chains or belts depending on specific engine code.
Transmission Fluid Change:
Manual: Inspect, replace if necessary. Automatic: Typically every 30,000 to 60,000 miles (48,000 to 96,000 km) or as per manufacturer recommendation, often using proprietary ATF.
Engine Oil:
API SN/SP, ACEA A3/B4, SAE 0W-30, 5W-30, or 5W-40 synthetic oil (specific viscosity depends on climate and engine). Refer to manual for exact spec.
Coolant:
G12 or G12+ (Pink/Red) ethylene glycol based coolant. Dilution with distilled water at 50/50 ratio.
Brake Fluid:

Common Problems:
Ignition coil failure, mass air flow (MAF) sensor issues, ABS sensor failures, oil leaks (valve cover, oil pan), coolant flange leaks, window regulator failures, CV axle boots cracking, timing belt tensioner wear (on applicable engines), catalytic converter issues.
Common Problems Detailed:
The 1.8T engine can suffer from sludge build-up if oil changes are neglected. PCV system failures can lead to vacuum leaks and rough idling. Suspension components, particularly control arm bushings, are prone to wear due to vehicle weight and road conditions.
