Most Nissan Altima models place the oil filter on the engine block on the passenger side, and the exact spot depends on the engine and model year. In many cars it’s a cartridge inside a round housing rather than a traditional spin-on filter, and some setups require removing a splash shield or undercarriage panel to reach it.
Understanding the variations by engine
The Altima has used several engines across generations, so the filter’s location can vary. The following guide covers the typical spots for the most common engines you’ll find in recent and older Altimas.
Common engines in Altima models
To locate it on your specific vehicle, start with the year and engine code, then check the service manual or a diagrams resource.
Here is a quick reference for where the oil filter tends to sit on the most common engines found in Altimas:
- 2.5L inline-4 engine (most newer Altimas, including recent generations): the oil filter is on the passenger side of the engine block, near the front. Many 2.5L engines use a cartridge-style filter inside a round housing that is accessed by removing a cap; you may also need to remove the front engine shield/undertray to reach it.
- 3.5L V6 engine (older Altimas and some earlier trims): the oil filter sits on the front-facing side of the engine block on the passenger side, often behind a small shield or cover and reachable from above after removing engine covers or shields.
- VC-Turbo 2.0L turbocharged engine (introduced in later years, around 2019–2023): the oil filter is typically located toward the bottom of the engine on the passenger side, sometimes behind an undercarriage shield; access may require removing panels for clearance.
Accessing the oil filter safely requires the engine to be cool, the car securely supported, and the appropriate tools on hand. If you’re unsure, consult the service manual for your exact year and engine code to locate and service the filter properly.
What you’ll need and how to prepare
Before you begin an oil change or filter replacement, gather the right tools and parts and follow safety steps. The list below covers common needs and precautions before you work.
- New oil filter of the correct type for your Altima’s engine
- Correct grade and amount of engine oil as specified in the owner's manual
- Drain pan, funnel, and rags for spills
- Wrench or socket set to remove the drain plug and filter cap (as applicable)
- Jack stands or ramps, if you need extra clearance under the car
- New drain plug washer (if required) and a silicone-based or thread-sealant on the filter cap as recommended
- Safety gloves and eye protection
Proper disposal of used oil and filters is essential; take them to a recycling center or an auto shop that accepts used oil.
Summary
The oil filter location on a Nissan Altima is not fixed; it varies by engine type and year. In most current 2.5L four-cylinder models, look on the passenger side of the engine block, often behind a shield or inside a cartridge housing. For older V6 or Turbo variants, check the front-side block area or the bottom side behind protective panels. Always verify with the owner's manual or a service diagram specific to your year and engine code to locate and service the filter safely.
