Here's a general guide:
1. Gather Supplies:
* New oil: Check your owner's manual for the correct type and amount (usually 4-5 quarts). Use the recommended weight, often 5W-30 or 10W-30.
* New oil filter: Again, check your owner's manual for the correct filter. Auto parts stores can help you find the right one based on your vehicle's year, make, and model.
* Oil filter wrench: The type you need will depend on your oil filter. Some are easier to remove by hand.
* Wrench for drain plug: Usually a 13mm or 14mm, but double-check.
* Drain pan: Large enough to hold at least 5 quarts of oil.
* Funnel: To help pour the new oil without spilling.
* Jack and jack stands (or ramps): For safe access to the oil pan. Never work under a car supported only by a jack.
* Gloves: To protect your hands.
* Rags or shop towels: To clean up spills.
2. Prepare the Car:
* Warm up the engine for a few minutes to thin the oil. This makes it drain easier. Don't let it get too hot.
* Securely position the car on jack stands or ramps. Engage the parking brake.
3. Drain the Old Oil:
* Locate the oil drain plug underneath the engine. It's usually towards the front.
* Position the drain pan underneath the plug.
* Carefully loosen and remove the drain plug using the correct wrench. The oil will be hot, so be cautious.
* Let the oil drain completely. This can take 15-20 minutes.
4. Replace the Oil Filter:
* Locate the oil filter. It's usually near the oil drain plug.
* Use the oil filter wrench to loosen and remove the old filter. Some oil will likely spill out, so have rags ready.
* Lightly lubricate the rubber gasket on the new filter with fresh oil.
* Screw on the new filter by hand, tightening it according to the instructions on the filter (usually about ¾ to 1 full turn after the gasket contacts the engine).
5. Replace the Drain Plug:
* Once the oil has finished draining, carefully screw the drain plug back into the oil pan. Tighten it securely with the wrench, but don't overtighten.
6. Add New Oil:
* Locate the oil fill cap (usually marked with an oil can symbol) on top of the engine.
* Remove the cap and use the funnel to pour in the correct amount of new oil (refer to your owner's manual).
* Add a little less than the full amount at first, leaving room to check the level.
7. Check the Oil Level:
* Replace the oil fill cap.
* Wait a few minutes for the oil to settle.
* Use the dipstick to check the oil level. The level should be between the minimum and maximum marks. Add more oil if necessary.
8. Start the Engine and Recheck:
* Start the engine and let it run for a few minutes.
* Turn off the engine and wait a few minutes.
* Recheck the oil level and add more if needed.
9. Dispose of Used Oil Properly:
* Take the used oil and filter to a recycling center or auto parts store that accepts them. Don't pour used oil down the drain or onto the ground.
Important Considerations:
* Safety First: Always use jack stands when working under a vehicle.
* Owner's Manual: This guide is general. Consult your owner's manual for specific instructions and torque specifications.
* Engine Type: The location of the oil drain plug and filter might vary slightly depending on whether you have the 3.1L or 3.8L engine.
If you are uncomfortable performing this task yourself, it's best to take your Intrigue to a qualified mechanic. This is a relatively straightforward process, but mistakes can lead to engine damage.
