Tools and Materials You'll Need:
* New oil: Check your owner's manual for the correct type and quantity of oil (usually 5W-30 or 5W-20, but this varies).
* New oil filter: Again, check your owner's manual for the correct filter type.
* Oil filter wrench: The type needed depends on your Suburban's oil filter. Some are easily removed by hand, others require a strap wrench or socket wrench.
* Wrench for drain plug: This is usually a 1/2-inch or 3/8-inch drive socket wrench, but check your owner's manual.
* Drain pan: Large enough to hold at least 6 quarts of oil.
* Funnel: To avoid spills when adding new oil.
* Jack and jack stands (or ramps): To safely lift the vehicle. Never work under a vehicle supported only by a jack.
* Gloves: To protect your hands.
* Rags or paper towels: For cleanup.
* Torque wrench (optional but recommended): To tighten the drain plug to the correct specification (found in your owner's manual).
Steps:
1. Warm up the engine: Run the engine for 5-10 minutes to warm the oil, making it flow more easily.
2. Prepare the vehicle: Park on a level surface, engage the parking brake, and chock the rear wheels.
3. Raise the vehicle: Safely lift the Suburban using a jack and secure it on jack stands. Alternatively, use ramps.
4. Locate the oil drain plug: It's usually located on the bottom of the oil pan. Consult your owner's manual if you're unsure of its location.
5. Drain the oil: Position the drain pan under the drain plug and carefully loosen the plug with the wrench. Once loosened, unscrew it by hand. Let the oil drain completely – this can take 15-20 minutes.
6. Locate the oil filter: This is usually near the oil pan.
7. Remove the oil filter: Use the appropriate wrench to remove the old oil filter. Be prepared for some oil to spill.
8. Lubricate the new oil filter gasket: Lightly lubricate the rubber gasket on the new oil filter with fresh oil.
9. Install the new oil filter: Screw on the new oil filter by hand, tightening it according to the manufacturer's instructions (usually about ¾ to 1 full turn after the gasket contacts the engine).
10. Replace the drain plug: Once the oil has finished draining, reinstall the drain plug and tighten it securely with the wrench. Use a torque wrench if you have one to tighten it to the correct specification (found in your owner's manual). Overtightening can damage the oil pan.
11. Lower the vehicle: Carefully lower the Suburban using the jack.
12. Add new oil: Use the funnel to pour the correct amount of new oil into the engine (check your owner's manual).
13. Check the oil level: Use the dipstick to check the oil level. Add more oil if necessary until it reaches the "full" mark.
14. Run the engine: Run the engine for a few minutes.
15. Check for leaks: Inspect the area around the drain plug and oil filter for any leaks.
16. Check the oil level again: After running the engine, turn it off and wait a few minutes before checking the oil level again. Add more oil if needed.
Important Safety Precautions:
* Always work in a well-ventilated area. Engine oil fumes are harmful.
* Never work under a vehicle supported only by a jack. Use jack stands for safety.
* Dispose of used oil properly. Most auto parts stores and recycling centers accept used motor oil.
* Be careful not to burn yourself on hot engine parts.
This is a general guide. Always refer to your owner's manual for the specific instructions and torque specifications for your Chevy Suburban's year and engine. If you are not comfortable performing this task yourself, it's best to take your Suburban to a qualified mechanic.
