The 2020 Kia Sorento uses a cartridge-style oil filter housed in a small canister, not a traditional spin-on filter. During an oil change you replace just the filter cartridge inside the housing, along with the O-ring seal on the cap.
Design and engine compatibility
In this model year, Kia uses a cartridge-type oil filter inside a housing for its available engines. Understanding this design helps you buy the correct filter kit and perform a proper service.
Engines offered in the 2020 Sorento
- 2.4-liter inline-4 gasoline engine (carb/Direct-Injection variants)
- 3.3-liter V6 gasoline engine
Both engine options share the cartridge-style filter setup, so confirm your exact engine by checking the VIN or owner's manual if you’re buying replacements. For oil viscosity, Kia typically recommends 5W-20 for many regions and 5W-30 in hotter climates or under heavier load, so always verify the specification for your area.
Oil type and filter replacement basics
To service the oil filter correctly, you’ll need a compatible cartridge filter element and the housing O-ring. Using the right filter element ensures proper filtration and fit, while replacing the O-ring prevents leaks after reassembly.
- Common oil grades: 5W-20 (most regions) or 5W-30 (hot climates or heavy use). Confirm the exact spec in your manual.
- Filter type: Cartridge filter element housed within a cap-style canister; you’ll replace the element and O-ring, not a full spin-on canister.
- Typical service items: cartridge filter, housing O-ring/gasket, and fresh engine oil for the change.
When shopping, look for OEM Kia/Hyundai cartridge filters or reputable aftermarket cartridge filters that match the Sorento’s housing size and gasket dimensions. Always verify compatibility with your engine code and model year.
How to identify the correct part and replace the filter
Before you begin, confirm your exact engine and part numbers, then follow a standard cartridge-filter replacement workflow. If you’re unsure, consult a dealer or trusted shop to avoid fitment issues.
- Warm up the engine briefly, turn off, and secure the vehicle with the parking brake. Gather the replacement cartridge, new O-ring, and fresh oil.
- Remove the filter housing cap to access the cartridge. Take out the old filter element and inspect the housing for debris.
- Clean the inside of the housing, replace the O-ring on the cap, and lightly oil the new O-ring to ensure a good seal.
- Install the new cartridge into the housing, reseal with the cap, and torque to the manufacturer’s specification.
- Refill with the recommended oil amount and grade, run the engine, check for leaks, and reset the oil life monitor if applicable.
After replacement, dispose of the old filter and oil responsibly. If you notice any leaks or abnormal noise, consult a technician promptly.
Where to buy and how to verify compatibility
To ensure you select the correct filter, use the engine code and year as your primary references. OEM Kia/Hyundai parts are the safest choice, but many reputable aftermarket cartridge filters are compatible as long as they match the canister size and gasket dimensions.
- Check the owner’s manual or the Kia/Hyundai official parts catalog for the exact cartridge filter part number.
- Ask a parts counter or service advisor to cross-reference by engine code and VIN to confirm fitment.
- When shopping online or at parts stores, verify that the product is a cartridge-type filter compatible with the Sorento’s filter housing and that it includes the correct O-ring.
If you’re unsure, rely on a certified technician or the dealer network to install the correct filter and avoid misfits that could cause oil leaks or filtration issues.
Summary
The 2020 Kia Sorento uses a cartridge-style oil filter inside a housing, not a traditional spin-on filter. Service involves replacing the cartridge element and the housing O-ring, using the appropriate oil grade for your region and engine. Verify compatibility with your exact engine (2.4L I4 or 3.3L V6) and consult the manual or a dealer to confirm the correct part numbers and service procedure. Regular replacement during oil changes helps maintain engine protection and performance.
