The oil filter location on a 2012 Nissan Altima depends on which engine is installed. If your car has the 2.5‑liter four‑cylinder (QR25DE), the filter sits on the passenger side of the engine block. If it has the 3.5‑liter V6 (VQ35DE), the filter is on the driver’s side near the front of the engine. This guide walks you through both setups so you can locate it quickly.
Oil filter location for the 2.5L QR25DE engine
Where to look and how to access it
For the 2.5L four‑cylinder, the oil filter is mounted on the passenger side of the engine block, toward the front of the engine compartment. It is a cylindrical spin‑on filter and is typically accessed from underneath the vehicle, often with the front wheel on the passenger side removed or an undercar shield loosened.
- The filter location is on the engine’s passenger side, near the firewall area.
- Access is usually from below the car; you may need to raise the vehicle and remove the splash shield for room to reach it.
- The filter is a standard spin‑on type and unscrews counterclockwise when viewed from the top of the engine bay.
For 2.5L QR25DE owners, locating the filter on the passenger side is common, but always confirm by visually inspecting the engine and the filter itself before loosening any connections.
Oil filter location for the 3.5L V6 engine
Where to look and how to access it
For the 3.5L V6, the oil filter is mounted on the driver’s side of the engine block, near the front of the engine. Like the 2.5L, it is a spin‑on filter and is typically accessible from beneath the vehicle with the front of the car supported and the wheel on the driver’s side removed or the undercar shield loosened.
- The filter location is on the driver’s side of the engine block, toward the front of the engine bay.
- Access is usually from underneath the car; raise the vehicle safely and optionally remove the driver’s side splash shield for extra room.
- The filter is a standard spin‑on type and unscrews counterclockwise when viewed from above the engine bay.
Owners with the 3.5L V6 should expect the filter on the driver’s side near the front of the block, and you may need to maneuver a bit to reach it around nearby brackets and hoses.
Safety and preparation notes
Regardless of engine, always prepare for an oil change by:
- Parking on a level surface and applying wheel chocks.
- Raising the car with a jack and supporting it on jack stands if you’ll be working from underneath.
- Having an oil drain pan, the correct filter, and the appropriate tools (filter wrench, sockets) ready.
If you’re unsure about locating the filter or working under the vehicle, consult the owner’s manual for your exact trim and engine variant, or seek assistance from a qualified mechanic.
Summary
In a 2012 Altima, the oil filter location varies by engine: the 2.5L QR25DE places the filter on the passenger side of the engine block, accessible from beneath the car; the 3.5L V6 places it on the driver’s side near the front of the block, also typically accessed from beneath. Always verify by briefly inspecting the area and refer to the owner's manual for your specific model, especially if you’re performing an oil change yourself.
