• ⚠️ Keep oil off belts, exhaust parts, and painted surfaces. Wipe spills right away.
• ⚠️ Used engine oil must be recycled properly at an auto parts store or recycling center.

📋 Before You Begin

• 🅿️ Park your Grand Cherokee on level ground and set the parking brake.
• 🧱 Place wheel chocks behind the rear wheels before lifting the front.
• 🌡️ If the engine is cold, run it for 2-3 minutes, then shut it off. Warm oil drains faster.
• 🔒 Open the hood and remove the oil fill cap. This helps the oil drain smoothly.
• 📱 No scan tool or infotainment service mode is required for this oil change.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and Secure the Front

• Use the floor jack rated 3-ton minimum to lift the front of your Grand Cherokee at a proper front lift point.
• Place jack stands rated 3-ton minimum under the front support points and lower the vehicle onto them.
• Use wheel chocks behind the rear wheels.
• Gently shake the vehicle by hand to confirm it is stable before crawling underneath.
• Stability first. Speed second.

Step 2: Position the Drain Pan

• Put on safety glasses and nitrile gloves.
• Slide the drain pan 10-quart minimum under the engine oil drain plug.
• Position the pan slightly behind the plug because oil may shoot outward at first.

Step 3: Remove the Oil Drain Plug

• Use a 13mm socket and 3/8-inch drive ratchet to loosen the drain plug.
• Finish removing the plug by hand while pressing inward slightly, then pull it away quickly.
• Let the oil drain until it slows to an occasional drip.
• Inspect the drain plug threads. Replace the engine oil drain plug gasket.
• Keep fingers away from the oil stream.

Step 4: Reinstall the Drain Plug

• Wipe the drain plug and oil pan sealing area with shop towels.
• Thread the drain plug in by hand first. This prevents cross-threading, which means the plug is started crooked and can damage the oil pan.
• Use the 13mm socket and 3/8-inch drive torque wrench to tighten the drain plug.
• Torque to 27 Nm (20 ft-lbs).

Step 5: Remove the Old Oil Filter

• Move the drain pan 10-quart minimum under the oil filter area.
• Use the oil filter wrench 93mm 15-flute with the 3/8-inch drive ratchet to loosen the oil filter.
• Unscrew the filter by hand once loose.
• Keep the open end of the filter facing upward as much as possible to reduce spills.
• Check that the old rubber gasket came off with the filter. A gasket is the rubber sealing ring on the filter.
• Double gaskets cause major leaks.

Step 6: Prepare the New Oil Filter

• Use your finger to apply a light film of clean engine oil 5W-20 full synthetic to the new filter gasket.
• This helps the gasket seal smoothly and makes the next oil change easier.
• Do not fill the filter before installation if it cannot be kept upright during installation.

Step 7: Install the New Oil Filter

• Thread the new engine oil filter on by hand until the gasket touches the mounting surface.
• Tighten it by hand an additional 3/4 turn.
• If using the oil filter wrench 93mm 15-flute, only snug it gently.
• Torque to 22 Nm (16 ft-lbs) if using a compatible torque setup.
• Do not overtighten the filter. It can crush the gasket and cause leaks.

Step 8: Add New Engine Oil

• Lower the vehicle if needed using the floor jack rated 3-ton minimum after removing the jack stands rated 3-ton minimum.
• Place a funnel in the oil fill opening on top of the engine.
• Add about 6.5 quarts of engine oil 5W-20 full synthetic first.
• Reinstall the oil fill cap by hand.

Step 9: Start the Engine and Check for Leaks

• Start the engine and let it idle for 30-60 seconds.
• Use safety glasses and look under the vehicle for leaks at the drain plug and oil filter.
• Shut the engine off and wait 5 minutes so the oil can drain back into the oil pan.

Step 10: Set the Final Oil Level

• Pull the dipstick, wipe it clean with shop towels, fully reinsert it, then pull it again.
• Add engine oil 5W-20 full synthetic through the funnel in small amounts until the level reaches the full mark.
• The normal refill capacity with filter is approximately 7 quarts.
• Do not overfill. Too much oil can cause foaming and engine damage.

Step 11: Reset the Oil Life Monitor

• Close all doors and press the ignition button to RUN without starting the engine.
• Use the steering wheel controls to select Vehicle Info > Oil Life in the instrument cluster display.
• Press and hold the OK button until the oil life resets to 100%.
• If the menu method does not reset it, keep ignition in RUN, fully press the accelerator pedal slowly 3 times within 10 seconds, then turn ignition off.
