The oil filter on a 2021 Kia K5 is located in the engine bay, attached to the engine block. Access varies by engine variant, so you may find it accessible from above behind the engine cover or from underneath behind the front bumper. Always verify with the owner's manual or a service manual for your exact engine code.
The K5 line uses more than one engine in 2021, most commonly a 1.6-liter turbocharged four and a 2.5-liter four. This guide explains typical locations and how to access them for a DIY oil change or simple inspection, noting that exact placement can differ by market and model year.
Oil filter location by engine type
The following overview summarizes where the oil filter is typically found for the two most common 2021 K5 engines. Exact placement can vary by market and model year, so if you don’t see it, check the service manual or ask a dealer for your VIN-specific guidance.
- 1.6-liter turbocharged inline-4 (GDI) engine: In many 1.6L turbo K5s, the filter is mounted in a cartridge-style housing on the engine, usually accessible from the top after removing the engine cover. The housing is typically near the front or side of the engine block and uses a replaceable cartridge rather than a traditional spin-on filter.
- 2.5-liter inline-4 engine: For the 2.5L engine configured K5s, the filter is typically mounted lower on the engine near the oil pan; service notes often require removing the front undercarriage splash shield to access the filter housing. It may be cartridge-type as well.
Note: Some regions or model updates may use different configurations. If you’re unsure, consult the Kia service manual for your VIN or ask a dealer for the exact location before attempting a change.
Accessing the filter for an oil change
Before attempting to service the oil filter, prepare your workspace and tools, as access may require lifting the car or removing shields when the filter is underneath.
- Park safely, engage the parking brake, and disconnect the battery if you’ll be lifting the car for an extended period.
- For top-side access: remove the engine cover if present, then locate the cartridge-style filter housing and unscrew the cap to replace the cartridge.
- For bottom-side access: raise the car on ramps or stands, remove the front splash shield to expose the lower oil filter housing or pan-side access point, and use proper protective gear to avoid burns from hot oil.
- Replace the O-ring and any gaskets, refit the cap, and replenish engine oil according to your engine’s specification and climate (check the owner's manual for the correct grade and capacity).
After changing the filter and oil, start the engine and check for leaks, then recheck the oil level with the dipstick and reset the maintenance reminders if applicable.
Tools and references
Having the right tools makes the job safer and easier. Gather these items before you begin.
- Correct oil type and capacity for your engine (check the owner’s manual; typical grades vary by engine and climate).
- New oil filter cartridge (or spin-on filter, depending on engine).
- Oil drain pan and funnel, suitable wrenches or sockets, including a socket for the filter cap.
- Gasket/o-ring kit for the filter cap, torque wrench, car ramps or jack stands, gloves, rags.
Having these items on hand will help you perform a proper oil and filter change with minimal downtime.
Summary
The 2021 Kia K5’s oil filter sits in the engine bay, but the exact spot depends on the engine variant. Top-side access is common with the 1.6L turbo, while some 2.5L configurations require bottom-access through the undercarriage shield. Always confirm the correct location for your VIN by consulting the owner’s manual or a Kia service manual, and proceed with caution if you’re working beneath the vehicle. If you’re unsure, a professional service can ensure a proper seal and correct oil specification.
