The engine oil in your Kia Sedona keeps all of the components of your engine lubricated to prevent damage from friction. Over time, the oil can break down and become less effective. If there is any debris or contaminants in the oil, change it to protect your engine. You should change the oil in your Sedona every 7,500 miles, according to the recommendations from Kia. Buy replacement filters and fresh oil from an auto parts store.
Open the bonnet of the Sedona and remove the engine cover. Use a wrench to remove the metal bolts securing the cover. Set the cover and bolts aside.
Remove the oil fill cap. Set the cap aside somewhere safe. Raise the front of your Sedona with a jack and set a pair of jack stands underneath to support it. Once the jack stands are secure, remove the jack.
Locate the oil drain plug in the oil pan beneath the engine. Position the drain pan beneath the plug and remove the plug with a wrench. Let the oil drain completely from the oil pan. Replace the drain plug and tighten it with a wrench.
Raise the car with the jack and remove the jack stands. Lower the car to the ground. Locate the oil filter on the right side of the engine block, near the rear. Remove the filter with an oil filter wrench. Use the oil filter wrench to remove the top of the filter canister and dump the filter out into the drain pan.
Insert a new filter into the canister and replace the cover. Replace the oil filter canister on the engine block and tighten it with the oil filter wrench. Fill the engine with 5W30 or 10W30 oil. The Sedona will take up to 6 quarts of oil in a full oil change.
Replace the oil fill cover and screw it tightly into place. Replace the engine cover and tighten the retaining bolts with a wrench. Close the bonnet and test-run the engine, monitoring the oil pressure gauge to be sure it is reading properly.
