⚠️ Safety & Precautions

• ⚠️ Let the engine cool until it is warm, not hot. Hot oil can burn skin.
• ⚠️ Support your Grand Cherokee with jack stands if you raise it. Never work under a vehicle supported only by a jack.
• ⚠️ Wear safety glasses and nitrile gloves. Used oil is dirty and can irritate skin.
• ⚠️ Keep oil off the exhaust and belts. Wipe spills right away with shop towels.
• ⚠️ Battery disconnect is not required for this oil change.

📋 Before You Begin

• 🧱 Place wheel chocks behind the rear wheels before lifting the front.
• 🌡️ Run the engine for 2-3 minutes if cold, then shut it off. Warm oil drains faster.

• 📱 The oil life reset is done from the instrument cluster, not through Uconnect.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and Secure the Front

• Use wheel chocks behind the rear tires.
• Use the floor jack rated 3-ton minimum at the front lift point to raise your Grand Cherokee high enough to work safely.
• Place jack stands rated 3-ton minimum under the proper front support points, then lower the vehicle gently onto them.
• Give the vehicle a light push from the side to make sure it is stable before going underneath.

Step 2: Remove the Lower Access Panel if Equipped

• Put on safety glasses and nitrile gloves.
• Use a plastic trim clip tool to remove any plastic push clips blocking access to the oil drain plug.
• Set the clips and panel aside in order so they go back in the same spots.
• Tip: Take a phone photo first.

Step 3: Remove the Oil Fill Cap

• Open the hood and remove the engine oil fill cap by hand.
• Lift the dipstick slightly by hand. This helps the oil drain smoothly.
• Place the funnel nearby, but do not add oil yet.

Step 4: Drain the Old Engine Oil

• Place the oil drain pan 10-quart minimum under the oil pan drain plug.
• Use a 13mm socket and 3/8-inch drive ratchet to loosen the drain plug counterclockwise.
• Remove the drain plug by hand while keeping pressure against it, then pull it away quickly to avoid dropping it into the oil pan.
• Let the oil drain until it slows to a drip. This usually takes 10-15 minutes.
• Inspect the drain plug and washer. Replace the washer or drain plug if damaged.

Step 5: Reinstall the Drain Plug

• Wipe the drain plug area clean with shop towels.
• Thread the drain plug in by hand first to avoid cross-threading. Cross-threading means the plug starts crooked and damages the oil pan threads.
• Use the 13mm socket and torque wrench 10-100 ft-lbs to tighten the drain plug.
• Torque to 27 Nm (20 ft-lbs)

Step 6: Remove the Oil Filter Cap

• From the top of the engine, locate the black oil filter housing near the front/top center of the 3.6L V6.
• Use a 24mm socket, 3/8-inch drive extension 6-inch, and 3/8-inch drive ratchet to loosen the oil filter cap counterclockwise.
• Lift the cap straight up slowly. Keep shop towels around it to catch drips.
• Remove the old paper filter cartridge from the cap by pulling it straight off by hand.

Step 7: Replace the Filter Cap O-Ring

• Remove the old O-ring from the filter cap by hand or carefully with a clean fingernail.
• Do not cut or scratch the plastic cap.
• Lightly coat the new oil filter cap O-ring with fresh SAE 0W-20 full synthetic engine oil.
• Install the new O-ring into the correct groove on the cap.
• Tip: Match the old O-ring position.

Step 8: Install the New Oil Filter Cartridge

• Push the new engine oil filter cartridge onto the oil filter cap by hand until fully seated.
• Lower the cap and filter into the housing carefully.
• Thread the cap clockwise by hand first.
• Use the 24mm socket, 3/8-inch drive extension 6-inch, and torque wrench 10-100 ft-lbs to tighten the oil filter cap.
• Torque to 25 Nm (18 ft-lbs)

Step 9: Refill the Engine Oil

• Place the funnel into the oil fill opening.
• Add SAE 0W-20 full synthetic engine oil slowly.
• Initial fill amount with filter replacement is about 5.9 quarts.
• Install the oil fill cap by hand.

Step 10: Start and Leak Check

• Make sure all tools are clear of the engine bay.
• Start the engine and let it idle for 30-60 seconds.
• Shut the engine off and inspect the drain plug and oil filter housing with safety glasses on.
• Use shop towels to wipe any oil residue so you can tell if a fresh leak appears.

Step 11: Check the Oil Level

• Wait 5 minutes after shutting the engine off so oil drains back into the pan.
• Pull the dipstick by hand, wipe it clean with shop towels, reinstall it fully, then pull it again.
• The level should be near the full mark without going above it.
• Add oil in small amounts through the funnel if needed.
• Tip: Do not overfill the engine.

Step 12: Reinstall the Lower Access Panel and Lower Vehicle

• Use the plastic trim clip tool to reinstall any lower panel clips removed earlier.
• 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 Grand Cherokee slowly to the ground with the floor jack rated 3-ton minimum.
• Remove the wheel chocks.

Step 13: Reset the Oil Life Monitor

• Use the steering wheel buttons to turn the ignition to RUN without starting the engine.
• Use the cluster controls to select Vehicle Info > Oil Life.
• Press and hold the OK button until the oil life resets to 100%.
• If that path is not shown, use this alternate pedal method: turn ignition to RUN, slowly press the accelerator pedal fully 3 times within 10 seconds, then turn ignition OFF.

• ✅ Confirm the oil life display reads 100%.
• ✅ Pour used oil into a sealed container and recycle it at an auto parts store or approved oil collection point.
• ✅ In Panipat, use a local authorized waste-oil recycler or service garage that accepts used engine oil. Do not pour oil into drains, soil, or trash.
