⚠️ Safety & Precautions

• ⚠️ Let the engine cool 15-30 minutes; oil can burn you.
• ⚠️ Support the vehicle with jack stands before going under it (never rely on a jack alone).
• ⚠️ Wear gloves and safety glasses; used oil is messy and irritating.
• ⚠️ Do not over-tighten the drain plug; the oil pan threads can strip.
• ⚠️ Battery disconnect is not required for this service.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear tires.
• Warm the engine for 2-3 minutes, then shut it off. Warm oil drains faster.
• Open the hood and remove the oil fill cap and dipstick (this helps the oil drain quicker).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and safely support the front

• Use a floor jack (rated 2-ton minimum) to lift the front of your CX-5 at the front center jacking point.
• Place jack stands (rated 2-ton minimum) under the front support points and lower the vehicle onto them.
• Give the vehicle a firm shake to confirm it’s stable before you go underneath.

Step 2: Open the lower splash shield access

• Under the front of the vehicle, locate the small service/access door in the lower splash shield (undercover).
• Use an 8mm socket with a 3/8" drive ratchet to remove the small bolts holding the access door, then swing/remove the door.

Step 3: Drain the engine oil

• Place a drain pan (at least 7-quart capacity) under the oil pan drain plug.
• Use a 10mm socket with a 3/8" drive ratchet to remove the drain plug, then let the oil drain fully (usually 5-10 minutes).
• Remove the old crush washer from the drain plug and install the new oil drain plug crush washer.

Step 4: Reinstall and torque the drain plug

• Thread the drain plug in by hand first (this prevents cross-threading).
• Use a torque wrench (3/8" drive) to tighten the drain plug: Torque to 30 Nm (22 ft-lbs).
• Wipe the area clean with shop towels so you can spot leaks later.

Step 5: Remove and replace the oil filter

• Move the drain pan under the oil filter area (a little oil will spill).
• Use an oil filter wrench (adjustable band type) to loosen the old filter, then spin it off by hand.
• Make sure the old rubber gasket (seal) did not stick to the engine. Double-gasket can cause a big leak.
• Put a thin film of fresh SAE 0W-20 oil on the new filter’s rubber gasket.
• Install the new filter by hand until the gasket touches, then tighten an additional 3/4 turn by hand.

Step 6: Reinstall the splash shield access door

• Reposition the access door and install the bolts using an 8mm socket with a 3/8" drive ratchet.

Step 7: Lower the vehicle

• Use the floor jack (rated 2-ton minimum) to lift slightly, remove the jack stands, then lower the vehicle to the ground.

Step 8: Refill with fresh oil

• Insert a funnel into the oil fill hole.
• Pour in 4.6 quarts of SAE 0W-20 full synthetic.
• Reinstall the oil fill cap and dipstick.

Step 9: Start, check for leaks, and verify oil level

• Start the engine and let it idle for 30-60 seconds.
• Shut the engine off and wait 3-5 minutes for oil to settle.
• Check underneath for leaks at the drain plug and filter using safety glasses.
• Check the dipstick and top off as needed (add small amounts using the funnel).

✅ After Repair

• Dispose of used oil and the old filter at an oil recycling center or auto parts store (never dump it).
• Re-check the dipstick the next day and top off if needed.
• Reset the oil maintenance reminder (your CX-5 may have one of these setups):
• 🧰 If you have a Maintenance menu:
  • Turn ignition to ON (engine off), then use the info controls to go to Settings > Maintenance > Oil Change > Reset.
• 🧰 If you do not see a Maintenance menu:
  • Tell me what warning you’re trying to clear (wrench light vs message), and I’ll give the exact reset steps for your cluster.
