The 2013 Elantra uses a cartridge-style oil filter mounted on top of the engine

The 2013 Hyundai Elantra has a cartridge oil filter — a cylindrical canister that screws directly onto the engine block rather than a spin-on filter that hangs below. This design sits on the passenger side of the engine, near the top, and is one of the easier filters to reach on this model. You do not need to lift the car or remove the wheel well to access it, though you will want the engine cool before you start.

The filter itself is a Hyundai part number 26300-35503 or an equivalent aftermarket cartridge. Most auto parts stores stock this filter under the 2013 Elantra specification, and it costs between $8 and $15 depending on the brand. The filter wrench you need is a standard cartridge wrench — a cup-shaped tool that fits over the canister — which costs $5 to $12 if you do not already own one.

Key Takeaways

  • The 2013 Elantra oil filter is a cartridge type mounted on top of the engine on the passenger side, not a spin-on filter underneath.
  • You will need a cartridge oil filter wrench, a drain pan, and a new rubber gasket that comes with most replacement filters.
  • The filter housing cap should be tightened by hand after installation, not with a wrench — over-tightening can crack the plastic housing.
  • Changing the filter takes 10 to 15 minutes once you have the right tools and the engine has cooled.

Locating the filter housing on your engine

Open your hood and look toward the passenger side of the engine bay. The oil filter housing is a black plastic cylinder about 3 inches tall with a cap on top. It sits between the engine block and the firewall, roughly level with the top of the engine. If you are standing in front of the car facing the engine, it is to your right, slightly back from the front edge.

The housing is bolted to the engine block and has a single large cap that unscrews. You do not need to remove any hoses, belts, or other components to reach it. If your engine is warm from recent driving, wait 10 to 15 minutes before you touch the housing — the coolant and oil inside are hot enough to burn skin.

Tools and parts you will need

Gather these items before you start: a cartridge oil filter wrench (the cup-shaped kind that fits over the canister), a drain pan large enough to hold at least 4 quarts, a new oil filter cartridge (Hyundai 26300-35503 or equivalent), and a clean rag or paper towels. Most replacement filters come with a new rubber gasket already attached to the cap, so you do not need to buy that separately.

If the gasket on your new filter is not pre-installed, you will also need a small tube of fresh gasket material or a replacement gasket ring. Check the package before you leave the parts store. A torque wrench is not necessary for this job — you tighten the cap by hand until the gasket contacts the housing, then turn it another three-quarters of a turn.

Step-by-step removal and installation

First, position your drain pan under the filter housing to catch oil that will spill when you remove the cap. Place the cartridge wrench over the filter cap and turn it counterclockwise to loosen. Once it is loose enough to turn by hand, unscrew it the rest of the way and lift the cap straight up. The old filter cartridge will come out with the cap.

Pour any remaining oil from the cap into your drain pan. Wipe the inside of the housing with a clean rag to remove debris and old oil residue. Check the rubber gasket on the old filter — if it stuck to the housing instead of coming off with the cap, peel it away carefully and discard it. Install the new gasket on the new filter cartridge if it is not already attached, then insert the new cartridge into the housing.

Screw the cap back onto the housing by hand. Once the new gasket makes contact with the housing (you will feel slight resistance), turn the cap an additional three-quarters of a turn. Do not use the wrench to tighten it — the plastic housing can crack if you over-tighten. Wipe away any spilled oil with your rag, close the hood, and start the engine to check for leaks around the cap.

What to do with the old filter and oil

The old filter cartridge and the oil you drained should be taken to a recycling center or auto parts store that accepts used oil. Most major chains — Autozone, O'Reilly, Advance Auto Parts, and Walmart — take used oil and filters for free, even if you did not buy your replacement parts from them. Some accept oil in a sealed container; others ask you to pour it into their collection tank.

Do not pour used oil down a drain or into the ground. Used motor oil is classified as hazardous waste in most states and contaminates groundwater. Keeping a sealed container in your garage until you have a few quarts to drop off is safe and legal.

Common mistakes to avoid

The most frequent error is over-tightening the filter cap. The housing is plastic, and the cap threads into it directly — if you use a wrench to tighten beyond hand-tight-plus-three-quarters-turn, you risk cracking the housing. A replacement housing costs $80 to $150 and requires more labor to install than the filter itself.

Another mistake is forgetting to install a new gasket. If the old gasket stuck to the housing and you did not replace it, the new filter will not seal properly and oil will leak around the cap. Always inspect the housing after you remove the old cap and install a fresh gasket with every filter change.

Do not confuse this cartridge filter with a spin-on filter. Some owners look for a filter wrench that fits a spin-on canister and waste time searching under the engine. The 2013 Elantra does not have a spin-on filter — the cartridge design is the only option for this model year.

When to change your oil filter

Hyundai recommends changing the oil filter every time you change the engine oil. For a 2013 Elantra, that interval is typically every 5,000 to 7,500 miles under normal driving, or every 10,000 miles if your car is equipped with the extended-interval maintenance schedule. Check your owner's manual for the exact interval that applies to your vehicle.

If you drive in severe conditions — frequent short trips, towing, dusty environments, or extreme heat — follow the shorter interval. The filter traps contaminants, and a clogged filter reduces oil flow and can damage the engine over time. Changing the filter at the recommended interval is one of the cheapest ways to extend engine life.

Frequently Asked Questions

Can I change just the filter without changing the oil?

Technically yes, but it is not recommended. The filter and oil work together — a new filter in old, dirty oil defeats the purpose of either. Hyundai and most mechanics recommend changing both at the same time. If you must change only the filter, expect to do it again within a few hundred miles.

What if oil leaks from the cap after I install the new filter?

Stop the engine and let it cool. Remove the cap and check whether the gasket is seated properly in the housing. If it is crooked or not fully inserted, reposition it and reinstall the cap. If the gasket looks fine, the cap may be under-tightened — turn it another quarter turn by hand and check again. Do not use a wrench.

How much oil will spill when I remove the filter?

Expect 1 to 2 quarts of oil to drain from the housing and filter cartridge. This is why a drain pan is essential — the oil is hot and messy, and it will run down the side of the engine if you do not catch it. Position the pan before you loosen the cap.

Is the cartridge filter more expensive than a spin-on filter?

Cartridge filters for the 2013 Elantra typically cost $8 to $15, which is comparable to spin-on filters for other vehicles. The main difference is that you also need a cartridge wrench if you do not already own one, adding $5 to $12 to your first filter change. After that, the wrench is reusable.
