Before installing the new filter, lubricate the rubber gasket with fresh oil. Screw in the new oil filter by hand until it's snug, and then tighten it according to the instructions on the filter or in your owner’s manual.
Replace the Drain Plug: Once the oil has drained completely, clean the drain plug and install a new crush washer if needed. Reinstall the drain plug and tighten it to the torque specification provided in your owner’s manual.
Fill with Fresh Oil: Locate the oil fill cap on the engine and remove it. Insert a funnel and pour in the correct amount of fresh oil, as specified in your owner's manual.
Check the Oil Level: Use the dipstick to check the oil level. Add more oil if needed to bring it to the correct level.
Check for Leaks: Start the engine and let it run for a few minutes. Check around the oil drain plug and oil filter for any leaks.
Dispose of the Old Oil: Properly dispose of the old oil and oil filter at a recycling center or auto parts store.

Replacing the Air Filter

A clean air filter is essential for the performance and efficiency of your engine. A clogged filter restricts airflow, which can reduce power and fuel economy. Here's how to replace the air filter on your 2012 Hyundai Sonata:

Locate the Air Filter Housing: The air filter housing is usually a large black box located near the engine. Refer to your owner’s manual for the exact location of the air filter housing.
Open the Housing: The air filter housing typically has clips or screws that hold it together. Carefully open the housing, taking care not to break any of the clips or damage the housing.
Remove the Old Filter: Take out the old air filter and inspect the housing for any debris or dirt.
Install the New Filter: Insert the new air filter into the housing, ensuring it fits snugly and correctly. Make sure you use the correct air filter for your specific model.
Close the Housing: Close the air filter housing and secure it with the clips or screws. Make sure the housing is properly sealed to prevent unfiltered air from entering the engine.

Replacing Brake Pads

Brake pads wear down over time and need to be replaced to maintain safe braking performance. Here's how to replace the front brake pads on your 2012 Hyundai Sonata:

Gather Your Supplies: You'll need new brake pads, a jack and jack stands, a lug wrench, a brake caliper tool (or a C-clamp), and a wrench or socket set.
Prepare the Car: Park the car on a level surface, engage the parking brake, and loosen the lug nuts on the front wheels.
Raise the Car: Use the jack to raise the car and secure it with jack stands. Always place the jack stands on a solid, weight-bearing part of the car's frame.
Remove the Wheel: Completely remove the lug nuts and remove the wheel.
Remove the Caliper: Locate the brake caliper and remove the bolts that secure it to the brake rotor. You might need to use a wrench or socket set.
Compress the Piston: Use a brake caliper tool or a C-clamp to compress the caliper piston back into the caliper. This creates space for the new brake pads.
Remove the Old Pads: Remove the old brake pads from the caliper.
Install the New Pads: Insert the new brake pads into the caliper. Make sure they are correctly positioned.
Reinstall the Caliper: Reinstall the brake caliper over the brake pads and rotor, and tighten the bolts to the manufacturer’s specifications.
Reinstall the Wheel: Put the wheel back on and tighten the lug nuts by hand.
Lower the Car: Lower the car, and then fully tighten the lug nuts in a star pattern.
Test the Brakes: Before driving the car, pump the brake pedal several times to ensure the brake pads are properly seated.

Engine Knocking

Engine knocking, also known as pinging or detonation, is a serious issue that can damage your engine. If you hear a knocking sound coming from your engine, it’s super important to address it right away. Common causes include using low-octane fuel when your engine requires high-octane fuel, carbon buildup in the combustion chamber, or issues with the ignition system. Here's how you can troubleshoot:
