For those of you who enjoy getting your hands dirty, we've included some step-by-step repair guides. These guides provide detailed instructions and illustrations to help you tackle common repairs on your 2021 Lexus LX 570 Sport. Let's start with changing your oil. First, gather your tools and materials, including new oil, a new oil filter, a wrench for the oil drain plug, and a drain pan. Next, warm up the engine, then locate the oil drain plug under the vehicle. Place the drain pan under the drain plug and remove the plug, allowing the old oil to drain.

Next, we can move onto replacing your brake pads. Gather your tools and materials, including new brake pads, a wrench or socket set, a jack and jack stands, and a brake caliper tool. Jack up the vehicle and secure it with jack stands. Remove the wheel, then locate the brake caliper. Use the brake caliper tool to compress the brake caliper piston. Remove the old brake pads and install the new ones. Reassemble the brake caliper and reinstall the wheel. Repeat this process for the other wheels. Finally, pump the brake pedal several times to ensure proper brake function. Another common repair is replacing a headlight bulb. Gather your tools and materials, including a new headlight bulb, a screwdriver or pliers, and gloves. Locate the headlight assembly. Refer to your owner's manual for the specific location. Disconnect the electrical connector from the headlight bulb. Remove the old bulb and install the new one, being careful not to touch the glass with your bare hands. Reconnect the electrical connector and reinstall the headlight assembly. And lastly, replacing a car battery. Gather the tools and materials, including a new car battery, a wrench set, and gloves. Locate the battery, usually under the hood. Disconnect the negative (black) terminal first, then the positive (red) terminal. Remove the old battery and install the new one, connecting the positive terminal first, then the negative terminal. Make sure all the cables are secure. These are just a few examples. Your owner's manual often has these step-by-step instructions. Always refer to your owner's manual and follow all safety precautions when performing repairs. If you're not comfortable with any of these repairs, it's always best to consult with a qualified technician.
