🔧 Maintenance

Oil Change Interval Gasoline:

Every 5,000 - 7,500 miles (8,000 - 12,000 km) or 6 months, depending on driving conditions and oil type used (refer to manual for exact recommendation).

Oil Change Interval Diesel:

Every 5,000 miles (8,000 km) or 6 months, as diesel engines often require more frequent oil changes.

Timing Belt Replacement Gasoline:

Not applicable for the G6CU 3.5L V6, as it utilizes a timing chain. This is a significant maintenance advantage.

Timing Belt Replacement Diesel:

Recommended every 60,000 - 90,000 miles (96,000 - 144,000 km) or 5-7 years for the J3 diesel engine's timing belt. Crucial to verify with manual.

Transmission Fluid Change Interval:

Every 30,000 - 60,000 miles (48,000 - 96,000 km), depending on transmission type and driving conditions. Manual strongly advises specific intervals.

Engine Oil Specification Gasoline:

API SN or higher, SAE 5W-30 is a common recommendation. Consult manual for specific Kia approved oils and viscosity grades.

Engine Oil Specification Diesel:

API CI-4 or CH-4 rated Diesel Engine Oil, SAE 5W-40 is often recommended. Crucial to use oils meeting specific diesel standards.

Coolant Specification:

Transmission Fluid Manual:

API GL-4 or GL-5 gear oil, viscosity typically 75W-90 or 80W-90. Capacity approx. 2-3 liters.

Brake Fluid Specification:

DOT 3 or DOT 4.

Common Problems Gasoline Engine:

Potential for oil leaks from valve cover gaskets, occasional catalytic converter issues, ignition coil failures, throttle body cleaning needs.

Common Problems Diesel Engine:

Turbocharger issues, injector problems (especially with fuel quality), EGR valve issues, glow plug failures, potential for exhaust manifold cracking (less common but possible).

Common Problems Transmission:

Automatic transmission shifting issues or overheating, manual transmission clutch wear.

Common Problems Suspension Steering:

Worn ball joints, tie rod ends, and bushings leading to clunking noises or steering wander. Rear shock absorber wear.
