Locating and Changing Your Nissan Altima's Oil Filter

Knowing the exact Nissan Altima oil filter location and replacement steps saves you time and prevents messy mistakes during a routine oil change. Depending on your model year, your vehicle might use a traditional spin-on metal canister or a newer eco-friendly cartridge style. Getting this process right keeps your engine properly lubricated and prevents frustrating oil leaks after you start the car.

Where is the oil filter located on a Nissan Altima?

The physical spot depends heavily on your engine size and model year. For most 2.5L four-cylinder models from 2013 onward, the filter is a cartridge type housed in a plastic cap located on the front side of the engine block, accessible right from the top. If you drive an older model or one with the 3.5L V6 engine, you will likely find a traditional spin-on metal filter underneath the vehicle, screwed directly into the engine block near the oil pan.

What tools do I need before starting?

Gathering your supplies beforehand keeps you from crawling out from under the car with dripping hands. You will need a few basic items:

A drain pan large enough to catch at least five quarts of fluid
A socket wrench and the correct socket for your drain plug
An oil filter wrench (a cup-style wrench for cartridge caps, or a strap wrench for spin-on metal cans)
Clean shop rags and nitrile gloves
A new oil filter and the correct viscosity motor oil
A replacement crush washer for the drain plug

How do I replace a top-mounted cartridge oil filter?

If your four-cylinder Altima has the top-mounted cartridge housing, the process is relatively clean since you do not have to reach under the car for the filter itself.

Warm up the engine for a few minutes so the oil flows easily, then turn it off and let it cool slightly.
Pop the hood and locate the black plastic filter housing cap on the front of the engine.
Place a small drain pan or thick rags directly beneath the housing to catch drips.
Use your cup-style oil filter wrench to loosen the plastic cap and unscrew it completely.
Pull out the old paper filter element and the old O-rings.
Lubricate the new large O-ring with a dab of fresh oil and install it into the groove on the new cap.
Push the new paper filter element into the housing until it clicks into place.
Thread the cap back on by hand to avoid cross-threading, then tighten it with your wrench to the manufacturer's specified torque.

How do I replace an under-car spin-on oil filter?

For models with the traditional metal canister, you will need to safely raise the front of the car using jack stands. Never rely solely on a hydraulic jack.

Slide your drain pan under the oil pan and remove the drain plug to let the old fluid empty out. While it drains, check your specific drain plug torque specs so you know exactly how tight to make it later.
Move the drain pan directly under the oil filter.
Use a strap or claw wrench to break the old filter loose, then spin it off by hand.
Wipe the mounting surface on the engine block clean with a rag.
Dip your finger in new oil and smear a light coat onto the rubber gasket of the new filter.
Screw the new filter on by hand until the gasket makes contact, then give it another three-quarter turn. Do not use a wrench to tighten it.
Reinstall the drain plug with a brand new crush washer.

How much oil does the Altima take after a filter change?

Refilling the engine requires precision. Adding too little causes oil starvation, while overfilling can blow out seals. The exact amount depends on your engine. You can check a detailed fluid capacity breakdown to see how the four-cylinder and V6 models differ. Generally, the 2.5L engine takes about 4.8 quarts, while the 3.5L V6 requires around 5.1 quarts.

Pour the fresh oil into the filler hole on top of the valve cover. If you live in a colder climate, make sure you select the right cold weather oil viscosity to ensure the engine turns over easily on freezing mornings. Start the engine and let it run for about thirty seconds. This fills the new filter. Turn the engine off, wait a minute for the oil to settle, and check the dipstick to ensure the level sits safely between the minimum and maximum marks.

What are common mistakes to avoid during this job?

Even experienced DIYers make avoidable errors when rushing through an oil change. Watch out for these specific issues:

The double gasket: When removing a spin-on filter, the old rubber O-ring sometimes sticks to the engine block. If you screw the new filter on top of it, oil will spray everywhere once the engine builds pressure. Always check the engine mounting surface.
Forgetting the cartridge O-rings: The top-mount housings use multiple O-rings. If you forget to swap the small one on the drain plug or the large one on the main cap, you will have a steady leak.
Over-tightening the plastic cap: The cartridge housing cap is made of plastic. Cranking it down with a breaker bar will crack the housing, forcing you to buy an entirely new cap assembly.
Reusing the crush washer: The metal crush washer on the drain plug deforms to create a seal. Reusing the old one is a primary cause of slow drips in the driveway.

For exact torque values and maintenance schedules specific to your VIN, you can always verify the details through the Nissan Owner's Portal. If you prefer to keep a physical copy of these instructions in your garage, printing them in a clean, readable typeface like Montserrat makes the text easy to read even when your hands are covered in grease.

Post-replacement checklist before driving

Before you put your tools away and take the car for a drive, run through this quick verification list:

Check that the oil filler cap is screwed on tightly.
Verify the dipstick shows the correct fluid level.
Look under the car to ensure the drain plug and filter are completely dry.
Start the car, let it idle, and watch the oil pressure light on the dash to confirm it turns off within a few seconds.
Inspect the filter area one last time for any fresh drips while the engine is running.
Reset the maintenance reminder light on your dashboard display.
Record the date and mileage in your maintenance log, and plan to recycle your old fluid at a local auto parts store.
