The oil filter on a Nissan Altima is typically located on the engine block on the passenger side near the oil pan, and can be accessed from underneath with the splash shield removed or from the engine bay depending on the engine. Exact location varies by model year and engine type.
By engine type: 2.5L QR25DE I4
For most Altimas equipped with the 2.5-liter QR25DE, the oil filter sits on the passenger side of the engine block, near the front, and is often accessible from beneath once you remove the lower splash shield or wheel well liner. Some versions use a cartridge-style filter inside a housing on top or beside the engine.
To locate it, follow these steps:
- Open the hood and inspect the right-hand side of the engine block near the oil pan or timing cover for a cylindrical canister or a filter housing.
- Look for a filter element inside a metal canister or a plastic cap that unscrews to reveal the filter.
- If it isn’t visible from above, remove the front splash shield or inner fender liner to view the underside area around the oil pan.
- Using a flashlight, trace the oil lines and the oil pressure switch area to guide you toward the filter housing.
Access to the QR25DE filter can vary by sub-model and year; many setups are reached from below, while some permit top-side access.
By engine type: VQ35DE 3.5L V6
For Altimas with the 3.5L V6, the oil filter is typically on the front-right side of the engine block (passenger side), near the bottom by the oil pan. Some variants use a cartridge-type filter inside a small housing on the side of the engine, which may require removing a cover to replace.
To locate it, follow these steps:
- With the hood open, examine the passenger-side of the engine block near the oil pan and exhaust manifold for a filter housing or a visible canister.
- If you see a housing with a cap, twist or remove the cap to access the filter element inside.
- If the filter isn’t visible, you may need to remove the right front wheel well splash shield to view the underside area around the engine.
- Refer to a service manual for your exact year, as some early V6 models place the filter slightly differently.
Most V6 Altimas place the oil filter in the same general area, but access can differ by generation and packaging of the exhaust and intake components.
Additional tips for locating and replacing the filter
If you’re unsure of your engine type or year, identify your engine code (QR25DE for the 2.5L, VQ35DE for the 3.5L) and consult the owner’s manual or a repair guide for your exact model. In some cases, the filter is cartridge-style inside a housing, which may look different than a traditional canister filter.
What to do if you can’t locate it quickly
Safe navigation of the engine bay is essential. Consider these steps: check the service manual for your VIN, search for engine bay diagrams specific to your year, or watch model-specific tutorials that show the exact filter location. If you live in a region with easy access to a garage, a quick scan under the vehicle with a flashlight often reveals the underside filter housing behind the right front wheel well.
Summary
Across most Nissan Altima models, the oil filter is mounted on the engine block toward the passenger side near the oil pan. Access may require removing protective shields or intrusions in the wheel well, and the exact location depends on whether you have a 2.5L QR25DE or a 3.5L V6 (VQ35DE). For the precise layout of your year and engine, consult the owner’s manual or a reputable repair guide for your VIN, and proceed with caution when lifting or wading into engine components.
