Before You Begin:
* Gather your supplies:
* New oil (refer to your owner's manual for the correct type and quantity – typically 4-5 quarts of 5W-30)
* New oil filter (check your owner's manual for the correct type)
* Wrench that fits your oil drain plug (usually a 13mm or 15mm – check your owner's manual)
* Oil filter wrench (depending on the filter type)
* Drain pan (large enough to hold at least 5 quarts of oil)
* Funnel
* Jack and jack stands (or ramps) – CRITICAL for safety
* Wheel chocks (for added safety)
* Rags or paper towels
* Gloves
* 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, though.
* Safety First: Never work under a car supported only by a jack. Always use jack stands. Engage your parking brake and chock the wheels.
Procedure:
1. Locate the oil drain plug: This is usually on the bottom of the oil pan, located underneath the engine. Consult your owner's manual if you are unsure of its location.
2. Position the drain pan: Place the drain pan under the oil drain plug.
3. Remove the drain plug: Carefully loosen and remove the drain plug using your wrench. Be careful, as the oil will be hot. Let the oil drain completely – this may take 15-20 minutes.
4. Replace the drain plug: Once the oil has drained, carefully replace the drain plug and tighten it securely with your wrench. Don't overtighten!
5. Locate the oil filter: This is usually near the oil drain plug, but its exact location varies depending on the engine. Consult your owner's manual if necessary.
6. Remove the oil filter: Use the oil filter wrench to loosen and remove the old oil filter. Some oil will likely spill, so be prepared.
7. Lubricate the new filter's gasket: Lightly lubricate the rubber gasket on the new oil filter with a little fresh oil.
8. Install the new oil filter: Screw on the new oil filter by hand until it's snug. Then tighten it according to the manufacturer's instructions (usually about ¾ to 1 full turn after it contacts the engine).
9. Add new oil: Using the funnel, carefully pour the correct amount of new oil into the engine. Refer to your owner's manual for the precise amount.
10. Check the oil level: Use the dipstick to check the oil level. Add more oil if needed, until it reaches the "full" mark.
11. Run the engine: Start the engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter.
12. Check the oil level again: After running the engine, turn it off and wait a few minutes for the oil to settle. Check the oil level again using the dipstick and add more oil if necessary.
13. Dispose of used oil properly: Take the used oil and filter to a recycling center or auto parts store that accepts them for proper disposal.
Important Notes:
* Consult your owner's manual: This guide provides general instructions. Always refer to your owner's manual for specific details and torque specifications for your 2000 Oldsmobile Alero.
* Safety is paramount: Always use jack stands and chocks. Never work under a vehicle supported only by a jack. Hot oil can cause serious burns.
* Regular oil changes are crucial: Follow the recommended oil change interval in your owner's manual to keep your engine running smoothly and extend its life.
If you are uncomfortable performing this task yourself, it's best to take your Alero to a qualified mechanic. This guide is for informational purposes only and does not replace professional advice.
