🔧 QX50 - Engine Oil & Oil Filter Replacement

Changing your oil and oil filter keeps your engine properly lubricated and helps prevent wear and sludge buildup. On your QX50, you’ll drain the old oil, replace the spin-on oil filter, then refill with the correct oil and reset the oil maintenance reminder.

Difficulty Level: Beginner | Estimated Time: 1-2 hours

⚠️ Safety & Precautions

• ⚠️ Work on level ground and support the vehicle with jack stands; never rely on a jack alone.
• ⚠️ Engine oil can be hot; let the engine cool until the oil pan is warm, not scorching.
• ⚠️ Keep oil off belts and exhaust parts to avoid smoke and smells.
• ⚠️ Wear gloves and safety glasses; used oil is a skin irritant.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Warm the engine for 2-3 minutes, then shut it off. Warm oil drains faster.
• Open the hood and remove the oil filler cap (this helps the crankcase vent while draining).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the front

• Use a floor jack to lift the front at the center front jacking point.
• Set the vehicle onto jack stands at the left and right front support points.
• Give the vehicle a gentle push to confirm it’s stable before you go underneath.

Step 2: Remove the lower splash shield (if equipped)

• Use a 10mm socket and 3/8" drive ratchet to remove the shield bolts.
• Use a trim clip remover to pop out any plastic push-clips (a trim clip remover is a fork-shaped tool that lifts clips without breaking them).
• Set the hardware aside in a small tray so nothing gets lost.

Step 3: Drain the old engine oil

• Place the drain pan under the oil pan drain plug.
• Use a 14mm socket and 3/8" drive ratchet to loosen and remove the drain plug.
• Let the oil drain until it slows to an occasional drip (usually 5-10 minutes).
• Remove the old crush washer and install a new drain plug crush washer on the drain plug.

Step 4: Reinstall and torque the drain plug

• Thread the drain plug in by hand first to avoid cross-threading.
• Use a torque wrench with a 14mm socket to tighten the drain plug.
• Torque to 34 Nm (25 ft-lbs)
• Wipe the area clean with shop rags so you can spot leaks later.

Step 5: Remove the oil filter

• Move the drain pan
• Use an oil filter wrench (band/strap type) to loosen the filter, then spin it off by hand.
• Make sure the old rubber gasket comes off with the old filter. Double-gasket can cause a leak.

Step 6: Install the new oil filter

• Put a light film of fresh oil on the new filter’s rubber gasket using a gloved finger.
• Spin the new filter on by hand until the gasket touches, then tighten by hand an additional 2/3 turn.
• If you are using a torque-capable filter tool and torque wrench: Torque to 18 Nm (13 ft-lbs)
• Wipe the filter area clean with shop rags.

Step 7: Reinstall the splash shield

• Reposition the shield and start all bolts by hand.
• Use a 10mm socket and 3/8" drive ratchet to snug the bolts and reinstall any push-clips using the trim clip remover.

Step 8: Refill with new engine oil

• Lower the vehicle off the jack stands using the floor jack.
• Insert a funnel into the oil filler opening.
• Pour in about 5 quarts first, then wait 1 minute and check the dipstick.
• Top off gradually until the level is at (not above) the upper mark on the dipstick.
• Reinstall the oil filler cap.

Step 9: Start, check for leaks, then recheck level

• Start the engine and let it idle for 30-60 seconds.
• Shut the engine off and look underneath for leaks at the drain plug and oil filter.
• Wait 5 minutes, then check the dipstick and top off if needed using the funnel.

Step 10: Reset the oil maintenance reminder

• Use the steering wheel buttons to open the vehicle information display settings.
• Navigate to Settings > Maintenance > Oil and Filter > Reset

✅ After Repair

• Verify the dipstick level is correct after your first short drive.
• Recheck for seepage around the drain plug and oil filter the next day.
• Take used oil and the old filter to an oil recycling drop-off location (many parts stores accept it).
