The 2008 Nissan Altima uses a cartridge-style oil filter housed in a canister, not a traditional spin-on filter. This design applies to both of the year’s available engines: the 2.5-liter four-cylinder and the 3.5-liter V6.
In the 2008 Altima lineup, buyers could choose either the 2.5L QR25DE engine or the 3.5L VQ35DE engine. In both cases, Nissan menetains a cartridge-style oil-filter setup inside a metal housing. Replacement involves swapping the filter element inside the canister and resealing the housing with a new O-ring. Below is a closer look at the engines and the filter arrangement, followed by practical guidance on replacement.
Engine options and filter design
2.5L QR25DE
The 2.5-liter QR25DE in the 2008 Altima uses a cartridge-type oil filter inside a canister. Maintenance involves replacing the filter element inside the housing and the cap O-ring, rather than exchanging a traditional spin-on filter. Access is typically from the front of the engine bay, and the process is integrated with the standard oil-change service.
3.5L VQ35DE
The 3.5-liter VQ35DE also utilizes a cartridge-style filter housed in a canister. Like the four-cylinder, you replace only the filter element and the housing O-ring during service. The steps are similar, though the housing may be located in a slightly different position on the engine, depending on the exact vehicle orientation.
Before attempting any filter replacement, confirm the engine in your vehicle, since some markets or trims may vary slightly in positioning or part numbers. The general cartridge-in-housing design is the common thread across both engines for 2008 Altimas.
What you’ll need to replace the oil filter
Below is a practical list of supplies and tools commonly needed to replace a cartridge-style oil filter in a 2008 Altima. This list is intended to guide a routine oil-change procedure and can be adjusted based on your shop setup.
- Replacement oil-filter cartridge compatible with the QR25DE or VQ35DE engine
- New O-ring for the filter housing cap
- Correct grade and amount of engine oil as specified in the owner’s manual
- Drain pan to catch old oil
- Funnel for refilling oil
- Wrench or strap wrench suitable for loosening the filter housing cap
- Rags or shop towels for cleanup
- Gloves for hand protection
Having the right filter cartridge and O-ring on hand helps ensure a proper seal and avoids leaks after the service. Always consult your owner's manual or a reliable parts catalog to confirm exact part compatibility for your engine variant.
Replacement steps for the cartridge oil filter
The following steps outline a typical cartridge-filter replacement procedure during a standard oil change. Use these as a general guide and follow the specific torque specifications in the service manual for your vehicle.
- Warm up the engine, then park safely on level ground. Place a drain pan beneath the oil pan and gather all materials.
- Shut off the engine and carefully remove the oil filler cap and the drain plug to drain the old oil into the pan.
- Use the appropriate tool (wrench or strap wrench) to loosen and remove the oil filter housing cap. Remove the old cartridge filter from the housing and discard it, along with the old O-ring.
- Clean the inside of the housing and inspect for any debris. Install the new O-ring into the housing cap groove or onto the cap as directed by the service manual.
- Insert the new filter cartridge into the housing. Reinstall the housing cap and tighten to the manufacturer’s specified torque.
- Reconnect the oil drain plug, replace the drain pan, and slowly refill the engine with the recommended amount and grade of oil.
- Start the engine and check for leaks around the housing cap. Then, verify the oil level on the dipstick and top off if necessary. Reset the oil-change indicator if equipped.
Following these steps helps ensure a proper seal and correct oil level after replacement. Always dispose of old oil and filters in accordance with local regulations.
Summary
The 2008 Nissan Altima, whether equipped with the 2.5L QR25DE or the 3.5L VQ35DE, uses a cartridge-style oil filter housed in a canister rather than a traditional spin-on unit. Replacing the filter involves swapping the cartridge inside the housing and the O-ring, along with a standard oil change. With the right parts and tools, the procedure is straightforward and can be performed during a routine maintenance visit or at home with careful attention to the manual’s specifications.
