The oil filter on typical Infiniti Q50 models sits in a cartridge-style housing on the engine block’s passenger side, usually requiring access from beneath the vehicle after removing the undertray. This location can vary slightly by model year and engine choice, so always verify with your manual.
Location and access
In the Q50 lineup, the oil filter is not in a traditional spin-on location. It is generally housed in a black plastic canister on the engine block’s passenger side, near the front of the engine. Depending on your year and engine variant (2.0T or 3.7L), you may need to remove the engine cover, and most models require taking off the undercarriage shield to reach the housing. If you’re unsure, consult the service manual for your specific year and engine code.
Note: If you are not comfortable performing an oil change or filter replacement, seek professional service. Always follow safety procedures and local regulations for oil disposal.
How to locate and replace the oil filter
Use these steps to locate and access the oil filter and prepare for replacement. The steps assume you are performing routine maintenance and can require lifting the vehicle and draining oil.
- Prepare the vehicle: Park on a level surface, engage the parking brake, and let the engine cool before starting any work.
- Gain access: If your Q50 has an undertray or splash shield, remove it to expose the engine and the oil filter housing on the passenger side of the engine.
- Drain the engine oil: Place a drain pan beneath the oil pan drain plug, remove the plug, and allow the oil to drain completely.
- Open the filter housing: Use the appropriate socket to loosen and remove the housing cap. Keep the cap and any O-rings safe for reinstallation.
- Replace the cartridge filter: Remove the old cartridge, inspect the O-rings, and install a new cartridge with a fresh O-ring if supplied with the kit.
- Reassemble and refill: Reinstall the housing cap with the correct torque, replace the drain plug if needed, add fresh oil to the recommended level, and start the engine to check for leaks.
After completing the steps, check the oil level with the dipstick and monitor for leaks around the filter housing. Dispose of used oil and the old filter properly according to local regulations.
Notes and tips
Always refer to the owner's manual for your exact year and engine type, as location can vary between the 2.0T and 3.7L variants. If you are not comfortable performing this maintenance, consult a qualified mechanic.
Summary
The oil filter on an Infiniti Q50 is located in a cartridge-style housing on the engine block’s passenger side, typically accessed from beneath after removing the undertray. Replacement involves removing the housing cap, swapping in a new cartridge, and reassembling with the engine oil replenished to the proper level. Always check your specific model year and engine for any variations.
