Instruction on how to change the oil on Kia 

Before you start.

  • The first step is to warm up the engine for a two to three minutes then turn off the engine. It will help with the suspended contaminations remix with the oil and drain out with the old oil.
  • Park the car in a level ground.

Step 1: Open Hood

Start by ensuring that the emergency brakes have been set. Next, locate the hood release found in the interior of the car. Pull the hood release until you hear the hood pop up. Move to the front of the car and release the latch, then lift up the hood.

Step 2: Raise vehicle

Jack up the front of the Kia using the jack that came with your car or an aluminum jack.

ALWAYS use jack stands to secure the car. Using ramps makes changing the oil a much easier job and safer. If you plan on changing the oil on regular basis you may want to consider investing in a set of ramps. Check out Amazon's Best Selling Car Ramps

Step 3: Remove Drain Plug & Drain Oil

The early model Kia?s had an access hole where you can drain the oil and remove the filter. Certain Kia models don't have the access holes so you will need to remove the 10 mm bolts and pull down the skid plate in order to remove access the oil filter and drain plug. kia optima oil changeWatch the following video on how to remove the engine skid plate from a 2016 Kia Optima. 

Locate the drain plug and remove the bolt. Use a 17 mm socket to remove this bolt by turning it counter-clockwise. Once you break the bolt loose, you can use your hands to remove the bolt. Make sure to have the oil catch pan located under the oil drain hole.diy oil change filter replace kia

IMPORTANT: Be careful when draining the oil. If the engine hasn?t cooled down the oil may be hot and cause burning. Allow at least five minutes for the old oil to drain. If time allows, let the oil drain for at least fifteen minutes or more. Clean the drain plug and the oil bolt using a clean dry cloth. Reinstall the drain bolt using your hand first. This will ensure that the bolt starts to go smoothly and no threads get damaged. If you have a new washer for the drain bolt make sure to install it. Tighten the oil drian plug by hand until it stops. Then tighten the bolt to 25 ft-lbs.  

Step 4: Remove and replace oil filter

Locate the oil filter. In the following picture the oil filter stands out as it is red.kia diy oil change 2.4 2.0 l engine guideThe filter can be removed by twisting it counterclockwise. Use oil filter tool such as TEKTON 12-inch oil filter pliers to remove the old oil filter. Oil may still be in the filter, so be careful as you remove the old filter to avoid spilling oil on your hands.diy oil filter oil type for kia optima sorento gdi

Screw the new oil filter in and tighten it by hand. If you prefer to use a torque wrench tighten the filter to 11.5 ft-lb.

Step 5: Add Engine Oil

Remove the oil filler cap on top of the engine. The oil filter cap should be labeled and usually has the recommended oil type stamped on it. Remove the cap by unscrewing it counterclockwise. Insert a funnel into the oil filler hole. Slowly pour the oil into the engine. Add the required quarts as indicated in your owner's manual. Once you add the recommended amount of engine oil, reinstall the filler cap.how to change kia oil yourself
