- Be sure to replace the oil filter with a new one every time you change the oil.
- Dispose of the used oil filter properly at a recycling center or automotive repair shop.
Draining the Old Oil
Now that you have gathered all the necessary tools and materials, you can proceed with draining the old oil.
Safety First: Ensure your vehicle is parked on a level surface and engage the parking brake to prevent any unexpected movement. Additionally, allow the engine to cool down for at least 30 minutes before starting the oil change process.
Step 1: Access the Oil Pan
Locate the oil pan underneath your vehicle. It is typically a large, black, or gray metal pan that holds the engine oil. Position your oil drain pan directly under the oil pan to collect the used oil.
Step 2: Remove the Oil Drain Plug
Using the appropriate wrench or socket, carefully loosen and remove the oil drain plug. Be mindful not to drop it into the oil pan or onto the ground. As you remove the plug, old oil will start draining out.
Step 3: Allow the Oil to Drain
Let the old oil drain completely into the oil drain pan. This process may take a few minutes, so be patient. Once the oil flow has slowed to a trickle, use a rag or paper towels to wipe any remaining oil around the drain plug and oil pan.
Step 4: Replace the Oil Drain Plug
Inspect the oil drain plug for any damage or wear. If the plug is in good condition, apply a small amount of new oil to the plug’s threads and reinstall it into the oil pan. Tighten the plug securely using the wrench or socket, ensuring it is snug but not overtightened.
Avoid overtightening the oil drain plug, as this can damage the threads or strip the pan, leading to potential oil leaks.
Replacing the Oil Filter
Once the oil has drained, it’s time to replace the oil filter. Locate the oil filter housing on the engine, usually a black plastic cylinder with a large cap. Using an oil filter wrench or your hands, carefully unscrew the cap and remove the old oil filter.
Before installing the new oil filter, apply a thin layer of clean engine oil to the rubber gasket around its base. This will help create a seal and prevent leaks. Screw on the new filter by hand until it’s snug, then use the wrench to tighten it another three-quarters of a turn.
Additional Oil Filter Details:
| Details | Description |
|---|---|
| Location: | Engine compartment, near the oil pan |
| Size: | Usually specified in the owner’s manual |
| Type: | Oil filters come in various types, including paper-based, synthetic, and reusable |
| Tightening: | Follow the manufacturer’s recommendations for proper tightening torque |
| Gasket: | Check the new filter for a rubber gasket and lubricate it before installation |
| Replacement Frequency: | Typically, every other oil change (refer to your vehicle’s maintenance schedule) |
Once the new oil filter is in place, check for any leaks around the cap and the drain plug. If there are no leaks, you can now add new oil to the engine.
Reinstalling the Drain Plug
6. Retighten the Drain Plug: Once the drain plug is thoroughly cleaned, it’s time to reinstall it. Start by applying a light coating of new oil to the washer surface of the plug. This lubrication ensures a proper seal and prevents leaks.
Next, carefully align and insert the drain plug into the oil pan. Use your hand to tighten it as much as possible, but avoid overtightening. Overtightening can damage the threads or cause the plug to strip, leading to potential leaks.
To ensure a secure seal, use a wrench or socket to further tighten the drain plug. However, do so gradually and cautiously. Note that most drain plugs require only 20-30 lb-ft of torque, which is relatively low. Excessive force can damage the plug or cause leaks.
As you tighten the drain plug, inspect the washer for any damage or deformation. If the washer appears warped or damaged, replace it with a new one to prevent leaks.
Adding New Oil
7. Add New Oil
Now, it’s time to add new oil to your Kia Sorento. Locate the oil filler cap on the top of your engine and remove it by turning it counterclockwise. Use a funnel to pour in the recommended amount and type of oil, as specified in your owner’s manual. The typical oil capacity for a 2021 Kia Sorento is around 5 quarts, but check the manual for your specific model and engine size.
As you fill the engine with oil, use the dipstick to check the level regularly. Insert the dipstick back into the oil tube, remove it again, and wipe it clean. Then, reinsert the dipstick and pull it out to check the oil level. Do this a few times to get an accurate reading.
The oil level should be between the “min” and “max” marks on the dipstick. If the oil level is too low, add more oil. If the oil level is too high, drain some oil out by removing the oil drain plug and draining a small amount into a container. Make sure the oil is warm before draining to ensure it flows out easily.
When you’re satisfied with the oil level, replace the oil filter cap and tighten it securely. Check for any leaks around the filter and cap once you’ve started the engine and let it run for a few minutes. If you see any leaks, tighten the filter and cap further or replace them if necessary.
Once you’ve confirmed that there are no leaks, reset the oil life indicator in your dashboard. This will ensure that the system will remind you when it’s time for your next oil change.
Checking the Oil Level
Checking the oil level is a quick and easy way to monitor your engine’s health. Here’s how to do it:
- Park your car on a level surface. This is important to ensure that the oil level is accurate.
- Turn off the engine and wait a few minutes for the oil to settle.
- Pop the hood. Locate the oil dipstick, which is typically marked with a bright color or the word “oil.” Pull out the dipstick.
- Wipe the dipstick clean with a rag or paper towel.
- Reinsert the dipstick and pull it out again. The oil level should be between the “MIN” and “MAX” marks on the dipstick.
- If the oil level is low, add oil to the engine. Use the type of oil recommended in your owner’s manual.
- Check the oil level again after adding oil. If the oil level is still low, there may be a leak. Have your car inspected by a mechanic.
- **Check the oil level regularly, especially before long trips.** This will help you catch any potential problems early on.
| Oil Level | Action |
|---|---|
| Between MIN and MAX | No action required. |
| Below MIN | Add oil to the engine. |
| Above MAX | Have your car inspected by a mechanic. |

2. Press and hold the “Trip” button located on the instrument panel until the “OIL LIFE” message appears on the display.
3. Press the “Reset” button to reset the oil life indicator.
4. The “OIL LIFE” message will disappear, and the new oil life percentage will be displayed.
Post-Change Inspection
10. Inspect Oil Level
Reinsert the oil dipstick and check the oil level. The mark should read between the “MIN” and “MAX” indicators. Add more oil as needed until the level is correct.
Ensure that the dipstick is reinserted properly and tightened securely before starting the engine.
Start the engine and let it run for a few minutes. This will circulate the oil throughout the system and bring it up to operating temperature.
Turn off the engine and wait a few minutes to allow the oil to settle.
Recheck the oil level on the dipstick. The level should still be between the “MIN” and “MAX” indicators.
| Oil Level Indicator | Action |
|---|---|
|
Below “MIN” |
Add more oil. |
|
Between “MIN” and “MAX” |
Oil level is correct. |
|
Above “MAX” |
Drain excess oil. |
If the oil level is still incorrect, repeat the process until the correct level is reached.
