🔧 Express - Engine Oil & Oil Filter Change

Changing the oil and filter keeps your 4.8L V8 properly lubricated and helps prevent engine wear. You’ll drain the old oil, replace the oil filter, then refill with the correct dexos-approved oil and reset the oil life.

Difficulty Level: Beginner | Estimated Time: 0.8-1.5 hours

⚠️ Safety & Precautions

• 🛑 Let the exhaust and oil pan cool a bit; hot oil can burn.
• 🛑 Support the van with jack stands on the frame; never rely on a jack alone.
• 🛑 Chock the rear wheels; your Express is RWD and can roll.
• 🛑 Keep oil off belts/hoses; wipe spills immediately.
• 🛑 Battery disconnect is not required for this service.

📋 Before You Begin

• Park on level ground and set the parking brake.
• Place wheel chocks behind the rear tires.
• Warm the engine for 2-3 minutes, then shut it off. Warm oil drains faster.
• If ground clearance is tight, raise the front with a floor jack and support with jack stands at the frame.
• Assumption: Oil capacity is about 6 quarts with filter for the 4.8L; always verify with the dipstick after filling.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fill point

• Open the hood.
• Remove the oil fill cap (twist by hand).
• Pull the dipstick up slightly (by hand). This helps the oil drain quicker.

Step 2: Drain the old engine oil

• Slide the drain pan (at least 10-quart) under the oil pan drain plug.
• Use a ratchet (3/8" drive) with a 15mm socket to loosen the drain plug, then finish removing it by hand.
• Let the oil drain until it slows to an occasional drip (usually 5-10 minutes).
• Inspect the drain plug threads and the sealing surface; replace the drain plug gasket/washer if your plug uses one.

Step 3: Reinstall and torque the drain plug

• Thread the drain plug in by hand first to avoid cross-threading.
• Use a torque wrench with a 15mm socket to tighten the plug: Torque to 25 Nm (18 ft-lbs).
• Wipe the area clean with shop towels so you can spot leaks later.

Step 4: Remove the old oil filter

• Move the drain pan under the oil filter (it will spill when you remove it).
• Use the oil filter wrench (76mm 14-flute) with a ratchet and socket extension to loosen the filter, then spin it off by hand.
• Make sure the old rubber gasket came off with the filter (it can stick to the engine). If it’s stuck, peel it off by hand using a shop towel.
• Double-gasket = guaranteed leak.

Step 5: Install the new oil filter

• Put a thin film of fresh oil on the new filter’s rubber gasket (dip a gloved finger into new oil).
• Thread the new filter on by hand until the gasket touches the engine.
• Tighten by hand an additional 3/4 turn. (Hand-tight is correct here; don’t use the wrench to tighten.)

Step 6: Refill with new oil

• Place a funnel into the oil fill opening.
• Pour in 5.5 quarts of SAE 5W-30 dexos1 to start.
• Reinstall the oil fill cap (by hand) and fully insert the dipstick.

Step 7: Start, check for leaks, and set the level

• Start the engine and let it idle for 30-60 seconds.
• With safety glasses on, look underneath for leaks at the drain plug and oil filter.
• Shut the engine off and wait 3-5 minutes for oil to drain back into the pan.
• Check the dipstick, then add oil in small amounts until it reaches the full mark (most end up near 6 quarts total).

Step 8: Reset the Oil Life Monitor

• Common Express method (no DIC): Turn key to ON (engine off). Fully press and release the accelerator pedal 3 times within 5 seconds. Turn key off, then start to confirm the oil life reset.
• If equipped with Driver Information Center (DIC) buttons: Turn key to ON (engine off). Use the cluster buttons to reach the oil life screen, then press/hold the reset button until it shows 100%.
• If it didn’t reset, repeat slower but within 5 seconds.

✅ After Repair

• Take a short 5-10 minute drive, then re-check for leaks with safety glasses on.
• Recheck the dipstick level on level ground and top off if needed.
• Dispose of used oil and the old filter at a recycling center or auto parts store that accepts waste oil.
