🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise the Front of the Tahoe

• Place the vehicle ramps directly in front of the front tires.
• Drive slowly onto the ramps until both tires are centered on top.
• Apply the parking brake, switch off the engine, and place the wheel chocks behind both rear tires.
• Push firmly on your Tahoe to verify that it is stable before going underneath.

Step 2: Open the Oil Fill Point

• Open the hood and locate the oil filler cap on top of the engine.
• Turn the cap counterclockwise by hand and remove it.
• Pull out the engine oil dipstick by hand and wipe it with a shop towel.
• Opening the cap helps the old oil drain smoothly.

Step 3: Drain the Used Engine Oil

• Put on safety glasses and nitrile gloves, then move underneath using the mechanic’s creeper.
• Position the 10-quart drain pan beneath the oil-pan drain plug. Allow room for the oil stream to travel outward initially.
• Use the 15mm socket and 3/8-inch-drive ratchet to loosen the drain plug counterclockwise.
• Finish removing the plug carefully by hand and let the oil drain completely.
• Wait until the oil has slowed to an occasional drip, normally about 10 minutes.

Step 4: Reinstall the Drain Plug

• Clean the drain plug and the sealing surface on the oil pan with shop towels.
• Install the new drain plug seal, then thread the plug clockwise by hand to prevent cross-threading.
• Use the 15mm socket and torque wrench to tighten the plug to 25 Nm (18 ft-lbs).
• Do not overtighten the plug; the oil pan threads can be damaged.

Step 5: Remove the Old Oil Filter

• Move the drain pan beneath the oil filter, which is mounted vertically near the rear underside of the engine.
• Use the adjustable strap-style oil filter wrench to turn the filter counterclockwise.
• Once loose, remove the filter by hand while keeping it upright.
• Check the engine’s filter mounting surface. Make sure the old rubber gasket did not remain stuck to it.
• Wipe the mounting surface clean with a shop towel.
• A doubled filter gasket causes a major oil leak.

Step 6: Install the New Oil Filter

• Apply a thin film of fresh SAE 0W-20 oil to the new filter’s rubber gasket using a gloved finger.
• Thread the new filter clockwise onto the mounting stud by hand.
• When the gasket first touches the mounting surface, tighten the filter by hand another three-quarters to one full turn.
• Do not use the filter wrench to tighten the new filter.

Step 7: Add Fresh Engine Oil

• Place the long-neck automotive funnel in the oil fill opening.
• Pour in seven quarts of SAE 0W-20 full-synthetic oil meeting the dexos1 specification.
• Add approximately three-quarters of the eighth quart, then remove the funnel.
• Install the oil filler cap clockwise by hand until secure.
• Insert the dipstick fully.

Step 8: Start the Engine and Check for Leaks

• Verify that no tools remain in the engine compartment or underneath your Tahoe.
• Start the engine and confirm that the oil-pressure warning goes out within a few seconds.
• Let the engine idle for approximately 30 seconds; do not rev it.
• Switch off the engine and inspect the drain plug and oil filter for leaks using a flashlight-free visual check from beside the vehicle.
• Do not crawl under your Tahoe while the engine is running.

Step 9: Lower the Vehicle and Set the Oil Level

• Remove the wheel chocks by hand and carefully reverse your Tahoe off the ramps onto level ground.
• Reapply the parking brake, switch off the engine, and wait five minutes.
• Remove the dipstick by hand, wipe it with a shop towel, insert it fully, and remove it again.
• Add small amounts of the remaining SAE 0W-20 oil through the long-neck funnel until the level reaches the upper crosshatched mark.
• Do not fill above the upper mark. Total capacity with a filter change is approximately 8.0 US quarts (7.6 liters).
• Reinstall the dipstick and oil filler cap securely by hand.

Step 10: Reset the Engine Oil Life System

• Switch the ignition on without starting the engine.
• Use the steering-wheel controls to open Driver Information Center > Info > Oil Life.
• Press and hold the check-mark button until the display resets to 100%.
• Switch the ignition off, restart the engine, and verify that the oil-life display remains at 100%.
