2. Draining the Old Oil: Locate the oil drain plug under the engine (consult your manual if you're unsure). Place the drain pan under the plug, then carefully unscrew the plug, allowing the old oil to drain out. Let it drain completely. This can take a while, so be patient. While the oil is draining, you can start removing the old oil filter. Be sure to dispose of the old oil properly, either by taking it to a recycling center or following your local regulations. Make sure to choose a drain pan that is large enough to contain all of the old oil. If the oil is hot, take extra precautions to avoid burns. Properly disposing of the oil protects the environment and avoids potential fines.

3. Replacing the Oil Filter: Locate the old oil filter (consult your manual for its location). Use the oil filter wrench to remove it. Before installing the new filter, lubricate the rubber gasket with a bit of fresh oil. Screw the new filter into place by hand, then tighten it according to the instructions on the filter (usually, a certain amount of turns after the gasket makes contact). This step is crucial for ensuring a proper seal and preventing oil leaks. Remember to check the instructions on the filter to avoid over-tightening. Doing so could damage the filter or its housing, resulting in oil leaks. It's a simple step that can prevent future headaches and ensure that your engine stays in optimal condition. Check that the old gasket comes off with the old filter.

4. Replacing the Drain Plug: Once the old oil has completely drained, clean the drain plug and install a new crush washer (if your kit includes one). Screw the drain plug back in and tighten it to the manufacturer's specifications (check your manual). Over-tightening can strip the threads, so be careful. Having a torque wrench is handy here, but if you don’t have one, just make sure it's snug. The drain plug is responsible for sealing the oil pan, and the crush washer provides a tight seal. Make sure to use the correct size and type of drain plug to ensure that it fits properly and doesn't leak. If you strip the threads, you may need to get the oil pan repaired or replaced.

5. Adding New Oil: Locate the oil fill cap on the engine (again, check your manual if you're unsure). Remove the cap and add the correct amount of new oil (remember, around 5.7 liters, but always check your manual). Use a funnel to avoid spills. Add the oil slowly and check the dipstick periodically to avoid overfilling. Overfilling can cause damage, so be sure to check and double-check. Once you've added the oil, replace the oil fill cap and make sure it's secure. Always add the oil in small increments and let the oil settle before checking the level using the dipstick. The dipstick is your primary tool for monitoring oil levels, so make sure to take your time and read it correctly.

6. Checking for Leaks and Final Steps: Start the engine and let it run for a few minutes. Check for any leaks around the drain plug and the oil filter. Turn off the engine and let it sit for a few minutes. Check the oil level on the dipstick and add more oil if needed. Dispose of the old oil and oil filter properly, according to local regulations. Finally, reset your oil change indicator, if your car has one. The oil change indicator alerts you when it's time for an oil change. It's easy to reset, so check your owner's manual for instructions. This helps you keep track of your oil change intervals. Properly disposing of the old oil and filter protects the environment and ensures that your vehicle is operating correctly.
