📋 Before You Begin

  • 🅿️ Park your CX-5 on level ground and set the parking brake.
  • 🛞 Place wheel chocks behind the rear wheels.
  • 🌡️ Warm the engine for 2-3 minutes, then shut it off. Warm oil drains faster.
  • 🧰 A torque wrench tightens bolts to an exact tightness so parts are secure without being damaged.
  • ♻️ Have a sealed container ready for used oil recycling.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and Support the Front

  • Use wheel chocks behind the rear tires.
  • Use a floor jack rated 3-ton minimum at the front center jacking point to raise the front of your CX-5.
  • Place jack stands rated 3-ton minimum under the proper front support points.
  • Gently lower the vehicle onto the jack stands and give the vehicle a light shake to confirm it is stable.
  • Never crawl under a jack-only vehicle.

Step 2: Remove the Lower Engine Cover Access Panel

  • Put on safety glasses and nitrile gloves.
  • Use an 8mm socket and 3/8-inch drive ratchet to remove the fasteners from the oil service access panel under the engine.
  • Move the panel aside and keep the fasteners together.

Step 3: Remove the Oil Filler Cap

  • Remove the engine oil filler cap by hand.
  • This helps the oil drain smoothly from the engine.
  • Pull the dipstick slightly upward by hand to let air enter the crankcase.

  • Position the drain pan 8-quart minimum under the oil drain plug.
  • Use a 17mm socket and 3/8-inch drive ratchet to loosen the drain plug counterclockwise.
  • Remove the plug carefully by hand and let the oil drain completely.
  • Wait until the oil flow slows to a drip.
  • Keep your hand away from hot oil.

Step 5: Replace the Drain Plug Washer

  • Use shop towels to wipe the drain plug clean.
  • Remove the old crush washer by hand.
  • Install the new engine oil drain plug crush washer by hand.

  • Use a 17mm socket and 3/8-inch drive torque wrench to tighten the drain plug.
  • Torque to 30 Nm (22 ft-lbs).
  • Wipe the area clean with shop towels.

Step 7: Remove the Old Oil Filter

  • Move the drain pan 8-quart minimum under the oil filter.
  • Use the oil filter wrench 65mm 14-flute and 3/8-inch drive ratchet to loosen the oil filter counterclockwise.
  • Unscrew the filter by hand and keep it upright to reduce spills.
  • Check that the old rubber gasket came off with the filter.
  • Double gaskets cause major oil leaks.

Step 8: Install the New Oil Filter

  • Use a clean finger with fresh 5W-30 full synthetic engine oil to lightly coat the rubber gasket on the new oil filter.
  • Thread the new spin-on engine oil filter onto the engine by hand.
  • Tighten until the gasket contacts the mounting surface, then tighten about 3/4 turn more by hand.
  • If using a 3/8-inch drive torque wrench with the oil filter wrench 65mm 14-flute, Torque to 14 Nm (10 ft-lbs).
  • Wipe around the filter with shop towels.

Step 9: Reinstall the Lower Engine Cover Access Panel

  • Place the access panel back into position.
  • Use an 8mm socket and 3/8-inch drive ratchet to reinstall the fasteners snugly.
  • Do not overtighten the small cover fasteners.

Step 10: Refill the Engine Oil

  • Place a funnel into the oil filler opening.
  • Pour in about 4.8 quarts of 5W-30 full synthetic engine oil first.
  • Reinstall the oil filler cap by hand.
  • Push the dipstick fully back in by hand.

Step 11: Start the Engine and Check for Leaks

  • Make sure all tools are clear of the engine bay.
  • Start the engine and let it idle for 30-60 seconds.
  • Turn the engine off.
  • Use safety glasses and inspect the drain plug and oil filter area for leaks.
  • Use shop towels to wipe any spilled oil so new leaks are easy to spot.

Step 12: Lower the Vehicle and Set Final Oil Level

  • Use the floor jack rated 3-ton minimum to raise the front slightly off the jack stands.
  • Remove the jack stands rated 3-ton minimum.
  • Lower your CX-5 to level ground.
  • Wait 5 minutes for oil to settle.
  • Pull the dipstick, wipe it with shop towels, reinsert it fully, then pull it again to check the level.
  • Add oil through the funnel in small amounts until the level is near the full mark.
  • Total refill is approximately 5.1 quarts with filter replacement.

Step 13: Reset the Maintenance Reminder

  • Turn the ignition on without starting the engine.
  • Use the center display controller to select Applications > Vehicle Status Monitor > Maintenance > Oil Change > Reset.
  • If your screen shows Scheduled Maintenance instead, select Applications > Vehicle Status Monitor > Maintenance > Scheduled > Reset.
  • Turn the ignition off when finished.

✅ After Repair

  • ✅ Start the engine again and confirm the oil pressure warning light turns off within a few seconds.
  • ✅ Take a short 5-minute drive, then park on level ground and recheck the oil level.
  • ✅ Look under your CX-5 for drips at the drain plug and oil filter.
  • ✅ Recycle the used oil and filter at an approved oil collection center.
  • ✅ Check the oil level again the next day to confirm it stayed full.
