What you need to know before starting

A Kia Sorento oil change takes about 30 to 45 minutes if you have done one before, or up to an hour if this is your first time. You will need to get under the vehicle, so a jack and jack stands (or ramps) are essential — never work under a car supported only by a jack. The job itself is straightforward: drain the old oil, replace the drain plug, swap the filter, and refill with new oil.

The amount and type of oil your Sorento needs depends on the year and engine size. Kia Sorentos from 2011 onward typically use 5.1 to 5.5 quarts of oil, but this varies by model year and whether your engine is the 2.0-liter turbo, 2.4-liter, or 3.3-liter V6. Check your owner's manual or the label under your hood for the exact capacity and the oil grade your engine requires — usually 0W-20 or 5W-30. Using the wrong grade can affect fuel economy and engine wear.

Key Takeaways

  • Drain the old oil while the engine is warm (not hot), replace the drain plug, then swap the oil filter before refilling.
  • Your Sorento's oil capacity and grade are printed in the owner's manual and on a label under the hood — do not guess.
  • You will need a jack and jack stands, an oil drain pan, a filter wrench, and a socket wrench to remove the drain plug.
  • The oil filter location and drain plug location differ slightly between model years, so consult your manual for the exact spots on your vehicle.
  • After refilling, run the engine for a few seconds, turn it off, wait a minute, then check the dipstick to confirm the level is correct.

Locating the drain plug and filter on your Sorento

The drain plug is on the underside of the engine, toward the front of the vehicle. On most Sorentos, it sits on the oil pan and is a bolt roughly the size of a quarter. The oil filter is usually mounted on the side of the engine block, though the exact location varies by year — some filters sit low and are straightforward to reach, while others require you to remove a wheel well liner or reach from above.

Before you start, consult your owner's manual for your specific model year. Kia's manual will show you a diagram of where both the drain plug and filter sit on your engine. If you do not have the manual, you can read it free from Kia's website by entering your vehicle identification number (VIN), or search for "[your year] Kia Sorento service manual" online. Taking two minutes to find the exact locations saves frustration later.

Tools and materials you will need

Gather these items before you start: a floor jack and jack stands (or ramps), an oil drain pan, a socket wrench that fits your drain plug (usually 17mm), an oil filter wrench, a new oil filter, and the correct amount and grade of new oil. You may also want a rag or old towel, a funnel for pouring oil, and a container to dispose of the old oil.

The oil filter wrench is important — trying to remove the filter by hand often fails and can damage the filter or your hands. A strap wrench or a cup-style wrench both work well. If you are unsure which filter wrench to buy, bring a photo of your filter to an auto parts store and ask which wrench fits. The new oil filter itself is inexpensive, usually $8 to $15, and the oil itself costs $20 to $50 depending on the grade and brand.

Steps to drain and replace the filter

First, warm up the engine by running it for a minute or two, then turn it off. Warm oil drains faster and more completely than cold oil. Raise the vehicle safely using a jack and find it with jack stands — never rely on a jack alone. Remove the plastic undertray or splash guard if your Sorento has one (usually held by a few plastic clips or bolts).

Position your drain pan under the drain plug. Using your socket wrench, loosen the drain plug by turning it counterclockwise, then unscrew it by hand once it is loose enough to grip. Let the oil drain completely — this takes 5 to 10 minutes. While the oil drains, locate the oil filter and position the drain pan underneath it as well, since some oil will spill when you remove it.

Once the oil has stopped dripping, wipe the drain plug clean with a rag and inspect the rubber washer on the plug. If the washer looks cracked or flattened, replace it (they are inexpensive). Screw the drain plug back in by hand first, then tighten it with your socket wrench — snug but not overly tight, as over-tightening can strip the threads.

Now remove the oil filter using your filter wrench, turning it counterclockwise. Let any remaining oil drain into the pan. Take the new filter and coat the rubber gasket (the ring on the top) lightly with new oil — just a thin layer. Screw the new filter on by hand until the gasket touches the engine, then turn it an additional three-quarter turn. Do not use the wrench to tighten the filter; hand-tight is correct.

Refilling and checking the oil level

Lower the vehicle back to the ground and remove the oil filler cap on top of the engine. Place a funnel in the opening and pour in the new oil slowly. Your Sorento's capacity is listed in the manual — start with about 80 percent of that amount, then check the level before adding the rest.

Start the engine and let it run for a few seconds, then turn it off and wait one minute. This allows the new oil to circulate and fill the filter. Remove the dipstick, wipe it clean, reinsert it fully, then pull it out again to check the level. The oil should be between the minimum and maximum marks on the stick. If it is low, add a little more oil and check again. If it is overfull, you will need to drain some out.

Once the level is correct, replace the oil filler cap and the dipstick. Check under the vehicle for any leaks around the drain plug and filter — a small drip or two is normal as things settle, but a steady stream means something is not tight enough. Let the engine cool, then dispose of the old oil at a recycling center or auto parts store; most accept used oil for free or a small fee.

How often to change your Sorento's oil

Kia recommends an oil change every 10,000 miles or every 12 months, whichever comes first, for most Sorentos built after 2011. Some newer models with synthetic oil may go longer — check your owner's manual for your specific year. If you drive in severe conditions (frequent short trips, towing, dusty environments), Kia recommends changing oil every 5,000 miles instead.

Keeping track of your oil changes helps your engine last longer and can protect your warranty. Many people mark their calendar or set a phone reminder based on their mileage. Some auto parts stores will also text or email you when your next change is due if you provide your vehicle information.

When to take your Sorento to a shop instead

If you do not have a safe place to work (a level driveway or garage), lack the tools, or feel uncomfortable working under a vehicle, a shop is the better choice. A quick-lube facility or dealership can complete an oil change in 20 to 30 minutes, usually for $40 to $80 depending on the oil type and location. This is money well spent if it means the job is done correctly and safely.

You should also visit a shop if you notice the drain plug is stuck or stripped, the filter is in an awkward location you cannot reach, or you see an unusual amount of oil leaking from the pan. These are signs that something may need professional attention beyond a routine oil change.

Frequently Asked Questions

What oil grade should I use for my Sorento?

Check your owner's manual or the label under the hood — most Sorentos use 0W-20 or 5W-30. Using the wrong grade can reduce fuel economy and increase engine wear. The first number (0W or 5W) refers to how the oil flows in cold weather, and the second number (20 or 30) refers to how it flows when hot. Both matter for your engine's performance.

Can I change the oil without a jack and jack stands?

No. Working under a vehicle supported only by a jack is dangerous — the jack can fail and the vehicle can fall on you. Ramps are a safer alternative to a jack and stands if you have a level surface to use them on. Never skip this safety step.

How do I know if my oil filter is on tight enough?

After hand-tightening the filter until the gasket touches the engine, turn it an additional three-quarter turn. You should not need a wrench to tighten it further. If you over-tighten with a wrench, you risk damaging the gasket and causing leaks when the engine heats up.

What should I do with the old oil?

Take it to a recycling center, auto parts store, or quick-lube shop — most accept used oil for free or a small fee. Never pour it down a drain or into the ground, as it contaminates water supplies. Many communities have hazardous waste collection days if you cannot find a regular drop-off location.

Why is my oil level dropping between changes?

Some oil consumption is normal, especially in newer engines or if you drive mostly on highways. If you are losing more than a quart between changes, have a shop inspect for leaks around the pan, filter, or drain plug. Internal engine wear can also cause excessive consumption, and a mechanic can diagnose the cause.
