The oil filter location on a 2018 Nissan varies by model and engine. In most 2018 Nissan vehicles with a conventional spin-on filter, you’ll find it on the front or side of the engine block near the oil pan, typically accessible from underneath after lifting the car and removing the splash shield. Some engines use a cartridge-style filter inside a small housing on the side of the engine; the exact spot depends on the engine code. To be sure, consult your owner's manual or service information for your model.
Overview
Location can differ across 2018 Nissan models because different engines use different filter designs. Always verify with the manual or a service professional if you’re unsure to avoid damaging components.
Common configurations
Spin-on oil filters
Most 2018 Nissan four-cylinder engines use the traditional spin-on oil filter. The filter is typically mounted on the front of the engine block and is reachable from underneath the vehicle, often behind the splash shield near the oil pan. You may need to remove the skid plate or splash shield to access it.
Cartridge-style oil filters
Some 2018 Nissan engines use a cartridge-type filter inside a small housing on the side of the engine. The housing is usually near the side or top of the engine. Replacing the cartridge involves removing the housing cap and swapping in a new cartridge and O-ring. The exact method and tools depend on the engine code; check your manual for details.
Locating the oil filter on your specific model
To locate the exact oil filter in your car, follow these steps:
- Check the owner's manual or the service/repair manual for your model and engine code.
- Open the hood and inspect the engine bay for a filter canister or a cartridge housing; look for a label that says "Oil Filter."
- If you don’t see it in the engine bay, check underneath the vehicle and behind the front splash shield for the filter or access panel.
- If the car has a skid plate, you may need to remove it to access the filter.
- If in doubt, consult a Nissan dealer or qualified mechanic.
Knowing your exact engine code (for example, 2.5L four-cylinder versus other variants) is key because the filter location changes by engine family.
DIY: changing the oil filter (tips and steps)
Before you begin, gather the right parts and tools and ensure the engine is cool. The steps below apply to many 2018 Nissan models and both filter types; always adapt to your engine's specifics.
What you’ll need
- New oil filter that matches your engine
- New oil filter O-ring if your model uses a cartridge with a replaceable seal
- Socket set and wrench for the filter housing or cap
- Oil drain pan, funnel, rags
- New engine oil of the correct grade and capacity
- Safety gloves and eye protection
Replacing the oil filter requires draining the oil, removing the old filter, and installing the new one with the correct torque on the housing cap or spin-on filter. After installation, pour in fresh oil and check for leaks, then run the engine and recheck the level.
How to perform the change (basic steps)
- Warm up the engine briefly, then turn it off and securely lift the car if needed and support with stands.
- Place a drain pan under the oil pan and remove the drain plug to drain the old oil; replace the drain plug seal.
- Locate and remove the old oil filter. If it’s a cartridge, remove the housing cap and extract the cartridge; replace with new cartridge and seal.
- Install the new filter (spin-on by hand snug; cartridge in housing per manual). Reinstall the housing cap or spin-on filter as appropriate and torque to spec.
- Replace the oil drain plug, add the recommended amount and grade of oil, start the engine and check for leaks; recheck the level and top up as needed.
Following these steps ensures a proper seal and avoids engine damage from leaks or over-tightening. If you’re unsure at any step, consult a professional.
Safety notes
Always work on a cool engine and securely lift the vehicle with jack stands. Wear gloves, eye protection, and dispose of used oil and filters at an approved facility. Do not over-tighten filter caps or spin-ons; torque to the manufacturer’s specification.
Summary
The oil filter location for a 2018 Nissan varies by engine design. Most 2018 Nissans with traditional spin-on filters have the filter on the front or side of the engine block, near the oil pan, accessible from underneath. Some engines use a cartridge filter inside a housing on the side of the engine. For an exact location, check your owner's manual or service documentation for your specific model and engine code, or consult a Nissan technician.
