⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface and keep the parking brake fully applied.
• ⚠️ Support the front of the Equinox with jack stands; never rely on a floor jack alone.
• ⚠️ Engine oil can be very hot; let the engine cool 15–30 minutes after driving.
• ⚠️ Wear safety glasses and gloves to protect from hot oil and sharp edges.
• ⚠️ Keep oil off the serpentine belt and exhaust components.
• ⚠️ Used engine oil is toxic; dispose of it at a proper recycling center.
• ⚠️ Battery disconnect is not required for this job.

📋 Before You Begin

• Park the Equinox on level ground, set the parking brake, and place wheel chocks behind the rear tires.
• Let the engine run for 3–5 minutes, then shut it off. This slightly warms the oil so it drains easier.
• Gather all tools and parts so you don’t have to crawl out mid-job.
• Battery does not need to be disconnected for this task.
• Plan where you will take the used oil and filter for recycling.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Safely lift and support the front

• Place wheel chocks behind both rear wheels.
• Position the floor jack (3-ton) under the front center jacking point (under the subframe crossmember).
• Raise the front of the Equinox high enough to work comfortably under it.
• Place jack stands (3-ton) under the front pinch welds or frame points on both sides and lower the vehicle onto them.
• Always shake the vehicle slightly to confirm it’s stable.

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

• Slide under the front with your safety glasses on.
• Use a flathead screwdriver to gently pry out any plastic clips holding the lower engine splash shield.
• If there are bolts, remove them using the appropriate socket and ratchet (often 10mm, if present).
• Lower the shield and set it aside.

Step 3: Position the drain pan

• Locate the oil pan at the bottom of the engine (toward the rear of the engine bay).
• Find the drain plug on the back or side of the oil pan (hex head, 15mm).
• Slide the oil drain pan under the drain plug, slightly offset toward the rear (oil will arc out).

Step 4: Remove the oil filler cap and dipstick

• Open the hood and locate the oil filler cap on top of the engine cover.
• Twist the oil filler cap off by hand to allow air in so oil drains faster.
• Pull out the dipstick and wipe it with a shop rag, then set it aside.

Step 5: Drain the old engine oil

• Under the Equinox, use a 15mm socket and 3/8" ratchet to loosen the drain plug counterclockwise.
• Finish removing the plug by hand; keep pressure inward until the last threads to avoid a sudden oil gush.
• Let the oil drain completely into the drain pan; this can take 5–10 minutes.
• Inspect the drain plug and washer; replace the washer if it looks crushed, cracked, or distorted.

Step 6: Reinstall and torque the drain plug

• Clean the drain plug area on the oil pan with a shop rag.
• Thread the drain plug back in by hand to avoid cross-threading.
• Use the 15mm socket and torque wrench to tighten the plug.
• Torque to 25 Nm (18 ft-lbs).
• Do not overtighten; the oil pan is aluminum.

Step 7: Remove the oil filter cap and cartridge

• Back up top, locate the black plastic oil filter housing near the front/top of the engine.
• Place a few shop rags around the housing to catch drips.
• Use a 32mm socket and 3/8" ratchet to loosen the filter cap counterclockwise.
• Lift the cap straight up; the paper cartridge filter will come out attached to the cap.
• Hold it over the drain pan and let excess oil drip off.

Step 8: Replace the filter and cap O-ring

• Pull the old cartridge filter off the cap by hand.
• Use a small flathead screwdriver to carefully lift the old O-ring off the filter cap groove.
• Wipe the cap clean with a shop rag.
• Install the new O-ring in the same groove on the cap, making sure it is not twisted.
• Lightly coat the new O-ring and the new filter’s rubber areas with fresh engine oil using your finger.
• Push the new cartridge filter onto the cap until it clicks or seats firmly.

Step 9: Reinstall and torque the oil filter cap

• Slide the cap with the new filter straight down into the filter housing.
• Thread it in by hand first to avoid cross-threading.
• Use the 32mm socket and torque wrench to tighten the cap.
• Torque to 25 Nm (18 ft-lbs).
• Stop as soon as the torque wrench clicks.

Step 10: Reinstall splash shield (if removed)

• Under the vehicle, position the lower splash shield back in place.
• Reinstall any bolts using the correct socket and ratchet (commonly 10mm).
• Press the plastic clips back into their holes using your fingers or a flathead screwdriver to assist.

Step 11: Lower the vehicle

• Use the floor jack to raise the front slightly and remove the jack stands.
• Lower the vehicle slowly to the ground.
• Remove the wheel chocks from the rear wheels.

Step 12: Fill with fresh engine oil

• Place the funnel in the oil filler opening on top of the engine.
• Pour in about 4.5 quarts of the new 5W-30 synthetic oil.
• Reinstall the oil filler cap by hand.
• Insert the dipstick back into its tube.

Step 13: Start engine and check for leaks

• Start the engine and let it idle for about 30–60 seconds.
• Look underneath with a flashlight for leaks at the drain plug and oil filter housing.
• If you see any drips, shut the engine off and gently snug the leaking connection with the proper socket and ratchet, then recheck.
• Turn the engine off and wait 5 minutes to let the oil drain back to the pan.

Step 14: Final oil level check

• Pull out the dipstick, wipe it clean with a shop rag, then reinsert fully.
• Pull it out again and check the level; it should be between the MIN and MAX marks, closer to MAX.
• If needed, add oil in small amounts (about 0.25 quart at a time) using the funnel, rechecking the dipstick each time.
• Total capacity with filter is about 5 quarts, but always go by the dipstick.

Step 15: Reset the oil life monitor

• Turn the ignition to ON (engine off) or start the engine.
• Use the button on the turn signal stalk to bring up the Driver Information Center.
• Press the MENU button on the stalk until you see the vehicle information menu.
• Scroll to Oil Life using the scroll switch on the stalk.
• Press and hold the SET/CLR button on the stalk until the oil life resets to 100%.
• Confirm any “Are you sure?” prompts if they appear.

Step 16: Clean up and handle used oil

• Pour the used oil from the drain pan into a sealed container (like the empty oil jugs) using the funnel.
• Place the old filter in a leak-proof bag.
• Wipe any spilled oil from the engine and underbody using shop rags and a little brake cleaner if needed.
• Take used oil and the old filter to a recycling or service center.

✅ After Repair

• Check under the Equinox again for any fresh oil leaks after a short drive.
• Recheck oil level with the dipstick after your first short drive and top off if needed.
• Note the mileage and date of the oil change for your records.
