You’ll be draining the old engine oil, replacing the oil filter, and refilling with fresh oil. This keeps your engine lubricated, clean, and running longer.

Difficulty Level: Beginner | Estimated Time: 1–1.5 hours

⚠️ Safety & Precautions

• ⚠️ Always work on a cool engine; hot oil can cause serious burns.
• ⚠️ Park on solid, level ground and use jack stands; never rely on the jack alone.
• ⚠️ Set the parking brake and keep the transmission in P.
• ⚠️ Wear safety glasses and gloves to protect your eyes and skin from oil.
• ⚠️ Used oil is hazardous waste; dispose of it at a recycling center, not in trash or drains.
• ⚠️ Keep rags away from the exhaust and catalytic converter under the car.

• Turn off the engine and let it cool for at least 20–30 minutes if it was hot.
• Gather all tools and parts so you don’t have to crawl out mid-job.
• Place wheel chocks behind the rear tires so the car cannot roll.
• You do not need to disconnect the battery for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and Support the Front of the Car

• Position the floor jack (3-ton) under the front center jacking point (under the subframe behind the front bumper).
• Pump the jack to raise the front high enough to place jack stands under the left and right front pinch welds (reinforced seams under the doors).
• Lower the car gently onto the jack stands and give the car a push to confirm it’s stable.
• Never work under a car supported only by a jack.

Step 2: Remove the Lower Engine Cover Access Panel

• Slide the oil drain pan and your tools under the front of the car.
• Locate the plastic under-cover (splash shield) under the engine; there is a small access panel near the oil pan and filter housing.
• Use the 10mm socket and 3/8" drive ratchet to remove any bolts holding the access panel.
• Use the trim clip removal tool or flathead screwdriver to gently pop out plastic clips if present.
• Remove the access panel and set the fasteners aside in a safe place.

Step 3: Loosen the Oil Filler Cap and Dipstick

• Open the hood and locate the engine oil filler cap on top of the engine cover.
• Turn the cap by hand counterclockwise to loosen or remove it.
• Pull out the dipstick slightly to allow air in; this helps oil drain faster.
• Set the cap where it won’t fall into the engine bay.

Step 4: Drain the Old Engine Oil

• Position the oil drain pan under the engine oil drain plug (rear of the oil pan, faces the rear).
• Use the 14mm socket and 3/8" drive ratchet to crack loose the drain plug.
• Finish unscrewing the plug by hand and keep a firm hold; then quickly pull it away so oil flows into the pan.
• Let the oil drain completely—this may take 5–10 minutes.
• Inspect the old drain plug gasket; remove it from the plug if stuck.
• Wipe the drain plug threads clean with a rag and install the new drain plug gasket.
• Thread the drain plug back in by hand to avoid cross-threading.
• Use the 14mm socket and torque wrench to tighten the drain plug to 39 Nm (29 ft-lb).
• Do not overtighten; the pan is aluminum.

Step 5: Remove the Oil Filter Cartridge Housing

• The 2.0L engine uses a cartridge-style oil filter, which sits in a reusable plastic housing under the engine.
• Move the oil drain pan under the oil filter housing (round plastic cap) near the front of the engine block.
• Some housings have a small plastic or metal plug in the center for pre-draining; if your filter kit includes a drain tool, you can remove this small plug first using a 3/8" drive ratchet and drain the housing.
• If you do not pre-drain, expect some extra oil to spill when removing the housing.
• Place the 64mm 14-flute oil filter cap wrench over the filter housing and attach the 3/8" drive ratchet or breaker bar.
• Turn counterclockwise to loosen and then unscrew the housing; keep it level as it comes off to avoid spilling too much oil.
• Dump the old filter and oil from the housing into the drain pan.

Step 6: Replace the Filter and O-Ring

• Pull the old filter cartridge out of the housing by hand.
• Use a flathead screwdriver gently to lift the old large O-ring off the housing groove (do not scratch the plastic).
• Lightly coat the new large O-ring with fresh engine oil using your finger; this helps it seal and prevents tearing.
• Install the new O-ring into the same groove on the housing, making sure it is not twisted.
• If your housing has a small center plug and the kit includes a small O-ring, remove the old small O-ring and install the new one in its place, lightly oiled.
• Push the new filter cartridge into the housing until it seats fully.
• Double-check O-ring is in correct groove, not higher up.

Step 7: Reinstall the Oil Filter Housing

• Wipe the filter mounting surface on the engine with a clean rag.
• Thread the loaded filter housing back onto the engine by hand; turn clockwise until it seats.
• Install the 64mm 14-flute cap wrench and use the torque wrench to tighten the housing to 25 Nm (18 ft-lb).
• If you removed a small center plug, tighten it (if separate) to about 13 Nm (10 ft-lb) with the correct tool.
• Wipe off any spilled oil with rags and a small amount of brake cleaner.

Step 8: Reinstall the Lower Engine Cover Access Panel

• Reposition the lower access panel under the engine.
• Reinstall any plastic clips by hand or using the trim clip tool.
• Use the 10mm socket and ratchet to reinstall the bolts snugly (do not overtighten; just firm).

Step 9: Refill the Engine with Fresh Oil

• Place the funnel into the oil filler opening on top of the engine.
• Pour in about 3.5 quarts (3.3 liters) of 0W-16 oil to start.
• Remove the funnel and reinstall the oil filler cap by hand.
• Push the dipstick fully back in.

Step 10: Start the Engine and Check for Leaks

• Remove tools from under the car, but leave the drain pan in place just in case.
• Start the engine and let it idle for 30–60 seconds.
• While the engine is running, look under the car with a flashlight:
  • Check around the drain plug for drips.
  • Check around the oil filter housing for leaks.
• If you see any leaks, shut off the engine and gently retighten the leaking part with the proper tool and torque.
• Turn off the engine and wait 5 minutes for the oil to settle.

Step 11: Check and Adjust the Oil Level

• After 5 minutes, pull out the dipstick, wipe it clean with a rag, then reinsert it fully and pull it out again.
• The oil level should be between the LOW and FULL marks, ideally near the top mark.
• If it’s low, use the funnel to add oil a little at a time (about 100–150 ml), rechecking the dipstick each time.
• Total capacity with filter is about 3.8 liters (4.0 quarts), but always go by the dipstick.

Step 12: Lower the Car and Final Cleanup

• Use the floor jack to lift the front of the car slightly off the jack stands.
• Remove the jack stands and lower the car fully to the ground.
• Check under the car one more time for any fresh drips.
• Pour the used oil from the drain pan into a sealed container for recycling.
• Wipe any spilled oil in the engine bay and on the engine cover.

Step 13: Reset the Maintenance Light (Oil Change Reminder)

• Turn the ignition to ON (engine off) with the START button (do not start the engine).
• Use the steering wheel controls to go to: Menu > Settings > Vehicle Settings > Scheduled Maintenance.
• Select Scheduled Maintenance, then choose Reset and confirm.
• Menu wording can vary slightly; look for “Maintenance Reset”.

✅ After Repair

• Take a short 5–10 minute drive, then park on level ground and recheck the oil level with the dipstick; top up if needed.
• Look under the car after the drive to confirm there are no new leaks.
• Verify the maintenance reminder is reset and no engine warning lights are on.
• Note the date and mileage of the oil change so you know when the next one is due.
