2013 Forte 2.0L I4 Engine
Oil Filler Cap - SAE 5W-20
Remove Oil Filler Cap
This automotive maintenance tutorial was specifically written to assist owners of the first generation (2010, 2011, 2012 and 2013) Kia Forte in changing the motor oil and replacing the canister style oil filter on the Hyundai Theta II 2.0 liter inline four cylinder motor.

Owners of other Kia or Hyundai vehicles such as the Optima, Cadenza, K900, Sorento, Sportage, Sedona, Soul, Elantra, Veloster, Sonata, Azera, Tucson, Santa Fe, Genesis, Cerato, Spectra, Accent, Sephia, i20, i30, ix35, i40 and Equus may also find these DIY instructions to be helpful.

The items needed to complete this procedure include a floor jack, two jack stands, a 17mm socket with a 3/8" drive ratcheting wrench, a used oil catch basin, an automotive funnel and 5 quarts of new SAE 5W-20 oil.

A few compatible replacement oil filters with their part numbers are as follows: Bosch 3312, Mobil 1 M1-104, Mahle OC 707, Royal Purple 10-2808, Fram PH9688, Purolator L14459, Wix 51334, Pennzoil HPZ-37 and Genuine Kia 26300-35503.

Pull Up Dipstick Handle
Raise Front of Vehicle
Black Metal Oil Pan
The first steps are to warm up the engine for a few minutes, park the vehicle on a level surface and then turn off the engine.

Then engage the emergency / parking brake and chock both sides of the rear wheels to prevent the car from moving.

Open the hood, twist off the oil filler cap in the counterclockwise direction and lift out the yellow plastic handled oil dipstick an inch or two.

Removing the oil filler cap and pulling up the dipstick handle will help prevent a vacuum from forming and allow the old oil to drain out more quickly.

Raise the front of the vehicle with the floor jack and securely support with at least two jack stands.

Slide under the front passenger side of the engine bay with the 17mm socket, 3/8" drive ratcheting wrench and the used oil catch basin.

Oil Drain Bolt - 17mm
Oil Filter - Front of Oil Pan
Used Oil Catch Container
The oil drain bolt is located at the rear edge of the black metal oil pan with the bolt head facing towards the back of the vehicle.

The canister style oil filter is located right in front of the oil pan on the opposite side of the drain bolt.

Slide the used oil catch basin to just below the drain bolt.

17mm Socket & Wrench
Loosen Oil Drain Bolt
Drain Out Old Oil
Loosen the oil drain bolt by turning it counterclockwise with the 17mm socket and 3/8" drive ratcheting wrench.

Be careful when you remove the oil drain bolt since the old oil may still be hot enough to burn your fingers.

Allow the old oil to drain out for at least a few minutes or until the flow slows to just an occasional drip.

If the oil drain bolt is equipped with a crush washer, inspect it and replace it if necessary. New crush washers can be purchased at your Kia or Hyundai dealership's parts counter or at most auto parts stores.


Tighten Bolt Clockwise
Move Basin Forward
Twist Off Old Oil Filter
Re-insert the oil drain bolt and spin it in a few turns by hand in the clockwise direction to prevent it from becoming cross threaded.

Tighten the oil drain bolt with the 17mm socket and ratcheting wrench to just past hand tight or about 25 ft-lbs of torque.

Slide the used oil catch basin to just below the old oil filter.

Twist off the old oil filter in the counterclockwise direction.

If you have trouble removing the old oil filter, you may need to use an oil filter wrench such as the Lisle # 63600.

Allow the old oil to drain out from the filter receptacle for at least a minute or two.

Dip Finger In New Oil
Lubricate Rubber O-Ring
Twist On New Filter
I recommend buying the Mobil 1 M1-104 oil filter since it has excellent reviews on Amazon.

Dip your pinky finger in to some new SAE 5W-20 oil and lubricate the rubber o-ring gasket on the new oil filter.

Lubricating the o-ring will allow it to form a better seal and also make it easier to remove it during the next oil change.

Double check that the rubber o-ring from the old oil filter is not still attached to the engine.

Twist on the new oil filter in the clockwise direction to about 1/4 to 1/3 turn past hand tight.

Make sure that the oil drain bolt and new oil filter are tight before moving on to the next steps.

Remove all of your tools and the used oil catch basin from below the engine bay.

Lower Car From Stands
Insert Automotive Funnel
Pour In New 5W-20 Oil
Carefully lower the car from the jack stands by using the floor jack.

Insert an automotive funnel in to the oil filler hole.

The Hyundai Theta II 2.0L I4 engine's total capacity for an oil change with filter replacement is 4.1 U.S. quarts (or 3.9 liters).

Only pour in about 3.5 to 3.75 U.S. quarts of the new SAE 5W-20 oil.

It is far better to have slightly less oil than necessary in the engine than to over fill it.

Running an engine that has been over filled with oil may cause damage to seals, gaskets or other components.

Replace Oil Filler Cap
Check Dipstick Oil Level
Re-Insert Dipstick
Temporarily replace the oil filler cap by twisting it on the clockwise direction and push down the dipstick.

Run the engine for a few minutes, turn it off and allow the oil to drain back down to the oil pan for at least 5 to 10 minutes.

Pull out the dipstick, wipe it clean, re-insert it and pull it out again to check the oil level.

If necessary, pour in more oil and repeatedly check the level on the dipstick until it reaches just at or below the "F" and metal dot that indicate the "Full" or "Maximum" line.

You may not need to pour in the entire 4.1 U.S. quarts (or 3.9L) of new oil in order for the oil level to reach the maximum line.

Once the oil is at the correct level, replace the dipstick and tighten the oil filler cap in the clockwise direction.

Be sure to record the oil change in your car's service records. It would also be a good idea to check your parking spot, garage or driveway for drops of oil which may indicate a leak from the drain bolt or the new filter.
