1. Gather Your Supplies:
* New oil: Consult your owner's manual for the correct type and quantity (typically 4-5 quarts for a 4-cylinder, slightly more for a V6). Use the recommended weight (e.g., 5W-30).
* New oil filter: Again, check your owner's manual for the correct filter. Have the old filter handy for comparison.
* Oil filter wrench: The type depends on your filter; a cap-type wrench or strap wrench works well.
* Wrench for drain plug: This is usually a 15mm or 13mm socket, but check your owner's manual.
* Drain pan: Large enough to hold at least 5 quarts of oil.
* Funnel: To avoid spills when adding new oil.
* Jack and jack stands (or ramps): Essential for safe access to the drain plug. 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 (check your owner's manual).
2. Prepare the Vehicle:
* Warm up the engine: Run the engine for 5-10 minutes to warm the oil, making it flow more easily. Don't let it get too hot to touch.
* Secure the vehicle: Raise the front of the vehicle using the jack and securely position it on jack stands. If using ramps, drive the vehicle slowly onto them. Engage the parking brake.
3. Drain the Old Oil:
* Locate the drain plug: It's usually located on the bottom of the oil pan, towards the front of the engine.
* Position the drain pan: Place it under the drain plug.
* Remove the drain plug: Carefully loosen and remove the drain plug using your wrench. The oil will flow out, so be prepared. Let it drain completely (this may take 15-20 minutes).
* Replace the drain plug: Once the oil has stopped dripping, carefully replace the drain plug and tighten it securely (but don't overtighten). If using a torque wrench, consult your owner's manual for the correct specification.
4. Change the Oil Filter:
* Locate the oil filter: It's usually near the top of the engine.
* Remove the old filter: Use the oil filter wrench to loosen and remove the old filter. Some oil will likely spill, so be prepared. Let the oil drain from the filter before discarding it properly.
* Lubricate the new filter's gasket: Lightly lubricate the rubber gasket on the new filter with fresh oil.
* Install the new filter: Screw the new filter on by hand until it's snug. Then tighten it an additional ¾ to 1 full turn. Don't overtighten.
5. Add New Oil:
* Locate the oil fill cap: It's usually located on the top of the engine, often marked with an oil can symbol.
* Remove the oil fill cap.
* Add new oil: Using the funnel, slowly pour in the correct amount of new oil as specified in your owner's manual.
* Check the oil level: After adding the oil, use the dipstick to check the level. It should be between the minimum and maximum marks. Add more oil if needed.
6. Clean Up and Lower the Vehicle:
* Dispose of the used oil and filter properly: Take them to a recycling center or auto parts store that accepts used oil.
* Lower the vehicle: Carefully lower the vehicle using the jack.
* Double-check oil level: After the engine has run for a few minutes, check the oil level again and add more if necessary.
7. Run the Engine and Check for Leaks:
* Run the engine for a few minutes: Check for leaks around the drain plug and oil filter.
* Check the oil level again: After running the engine, let it sit for a few minutes before checking the oil level one last time.
Important Notes:
* Consult your owner's manual: This guide provides general instructions, but your owner's manual has specific information for your vehicle. Always prioritize your owner's manual.
* Safety first: Always use jack stands when working under a vehicle. Never work under a vehicle supported only by a jack. Wear safety glasses.
* Proper disposal: Used oil and filters are hazardous waste and should be disposed of properly.
This detailed process should help you successfully change the oil in your 2002 Chevy S-10. If you're uncomfortable performing this task yourself, it's always best to have a qualified mechanic do it.
