Maintenance
|
|
Service Intervals
|
|
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.
|
|
Fluid Specifications
|
|
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:
|
Ethylene Glycol-based coolant (typically Orange or Pink Asian vehicle type), HOAT (Hybrid Organic Acid Technology) or OAT (Organic Acid Technology) compatible. Kia Long Life Coolant is often specified. Capacity approximately 8-9 liters.
|
|
Transmission Fluid Automatic:
|
Dexron-III or equivalent (e.g., Mercon, SP-III). Capacity approx. 8-10 liters for a full flush/fill.
