The DIY Oil Filter Change: A Step-by-Step Breakdown
When should you check engine oil level? A good rule of thumb is to check it every time you fill up with gas or at least once a month. But when it's time for an oil change, replacing the oil filter is a non-negotiable part of the process for your 2018 Nissan Frontier. This procedure is well within the reach of the average DIYer, saving you money and giving you peace of mind.
Tools and Supplies You'll Need
Gathering your supplies beforehand makes the job smoother. For a 2018 Nissan Frontier oil filter change, you'll typically need:
- New 2018 Nissan Frontier oil filter (ensure it's the correct part number).
- New engine oil (check your owner's manual for the correct type and quantity).
- Oil filter wrench (cup style or strap wrench, depending on accessibility).
- Wrench for the oil drain plug.
- Drain pan capable of holding at least 5 quarts of oil.
- Funnel.
- Rags or shop towels.
- Gloves to keep your hands clean.
- Jack and jack stands (if needed for access).
Step-by-Step Procedure
This is how you check car oil and change the filter:
- Warm Up the Engine: Run the engine for 5-10 minutes. Warm oil flows better and carries more contaminants out.
- Safely Lift the Vehicle (If Necessary): Use a jack and secure jack stands under the frame rails for stable support. Never work under a vehicle supported only by a jack.
- Locate the Drain Plug and Filter: The oil drain plug is usually at the lowest point of the oil pan. The oil filter on a 2018 Frontier is typically found on the front or side of the engine block.
- Drain the Old Oil: Place the drain pan beneath the drain plug. Carefully loosen and remove the plug with your wrench, letting the old oil drain completely. This can take several minutes. Once drained, reinstall the drain plug, tightening it securely but not overtightening.
- Remove the Old Oil Filter: Position the drain pan under the oil filter. Use your oil filter wrench to loosen it. Once loose, unscrew it by hand. Be prepared for a small amount of oil to spill out.
- Prepare the New Filter: Apply a thin film of new engine oil to the rubber gasket on the new oil filter. This helps create a good seal and makes future removal easier.
- Install the New Filter: Screw the new filter onto the engine by hand until the gasket makes contact. Then, tighten it an additional 3/4 to 1 full turn, or as specified by the filter manufacturer. Do NOT overtighten with a wrench.
- Add New Oil: Remove the oil fill cap on top of the engine. Using a funnel, add the correct amount and type of new oil specified in your owner's manual.
- Final Checks: Reinstall the oil fill cap. Start the engine and let it run for a minute. Check for leaks around the drain plug and oil filter. Turn off the engine, wait a few minutes, and then check the oil level using the dipstick. Add more oil if needed to reach the 'full' mark.
Lubricate the new oil filter's rubber gasket with a bit of fresh oil before installation. This simple step prevents it from seizing and ensures a proper seal for the next oil change. It's the little things that truly count.
Regular oil filter changes are a cornerstone of effective oil maintenance. Your 2018 Nissan Frontier's engine will thank you for it, ensuring what's normal oil pressure remains consistent and performance stays high.
