Next, disconnect the black cable, then the red cable, and remove the battery from the vehicle. After that, detach the other ends of the cables from the engine block in the same order.

Then, install new cables by attaching the red cable to the starter and the black cable to the engine block before putting the battery back in. Finally, connect both cables to the battery before starting the car to make sure that it works. For tips on how to handle rusted bolts or bolts that are hard to loosen, keep reading!

Car batteries contain a mixture of sulphuric acid and water that could cause serious harm if it gets into your eyes.

Ensure the car is turned off. If your car is a standard, make sure the parking brake is engaged instead of having the car in park. Locate the battery. Different automakers place the batteries in their cars in different locations for a number of reasons. Most car batteries can be located near the front or nose of the car on the left or right.

It looks like a large, usually black box with two metal terminals sticking out of the top, each with cables attached. Make sure the hood struts can support the weight of the hood before you release it, otherwise it could fall and hurt you.

If you cannot locate the battery under the hood of the car, it may be in the trunk. It will show you how to locate and access your battery. Determine which is the positive and which is the negative terminal. Once you have located the battery, you will need to differentiate between the positive and negative terminals. Car battery cables are usually colored to match their use: red cables are positive, black cables are negative. In some cases, the wires may both be black, but they will have red and black boxes or accents at the ends of the cable.

Negative cables bolt directly to the body of the car or engine block, positive cables attach to the starter. The plus is the positive cable terminal, the — is the negative. Part 2 of Remove boxes or tape covering the end of the cable.

You will often find other wires attached to a battery cable using electric tape particularly on the positive side. Sometimes these wires are held in place more securely using metal or plastic retainers. Do not remove these wires, but cut off any tape that prevents you from reaching the bolt that keeps the cable secured to the terminal. Be careful not to cut any wires when trying to access the bolts.

Disconnect the negative cable. The negative cable, which is also called the ground cable, should be the first you disconnect. Once you disconnect this cable, the car will no longer have a completed electrical circuit, and you may notice any dashboard, interior or engine bay lights that were on will instantly shut off. This indicates that the battery is no longer connected to the car in a manner that can power it.

If the bolt is seized or will not turn, try spraying some WD on it. It will eat away some of the rust and oxidization and allow the bolt to turn more freely. Do not allow the negative cable to come into contact with the positive terminal at any time. Disconnect the positive cable. Because the negative cable is the one most often disconnected while working under the hood of a car, the positive one may by slightly more difficult to remove. Once the positive cable is disconnected from the battery, the battery will be completely disconnected and may be removed.

If your battery is in the trunk, the positive cable will attach to another connector near the body of the car. Simply disconnect it from there. Remove the battery.

Some cars will not require the removal of the battery while replacing battery cables, but even if it is not necessary, it may make the process easier. Removing the battery can free up room to work and removes any possibility of the cables coming back into contact with their terminals and shocking you. Removing this bracket usually requires unscrewing two bolts.

Make sure to set the battery upright after removing it from the car. Remove the negative cable, then the positive. Start by following the negative cable from the now loose end back to where it is bolted to the engine block or body of the car. Take note of how it is routed so you can follow the same path with the new cable. Once you locate the other end, use a wrench to remove the bolt that holds the negative cable in place.

Then repeat the process for the positive cable, which will be attached to the starter on the other end. Compare the new and old cables. With both the positive and negative cables removed, compare them to your replacement cables. If you purchased cables specific to your car, they should match in length and have the same terminal connectors at each end. If you are using universal cables that you cut to length, use the old cables as your guide.

Make sure the connecting ends at either side of the new cables match the old ones for easy installation. Part 3 of Prepare the new cables for installation. You will also need to ensure that there is no paint or dirt stuck on the new cable ends before you install them. You can use a steel-toothed brush to clean off the connector ends of the cables in order to ensure a good electrical connection. Attach the positive cable to the starter. Use the same bolt you removed to disconnect the old cable to attach the new one in its place.

If the bolt is rusted, you may want to use a steel wire brush to remove the rust from the bolt and ensure a proper connection. If it is too rusted, you may need to replace it. Run the new positive cable back through the engine bay in the same way the old one was. Attach the negative cable to the body or block.

Locate the hole the old negative cable was attached to and use the same bolt to connect the new cable. Once again, ensure the bolt is in good enough condition to hold the cable in place and allow electricity to pass through the cable. Use a flashlight to ensure neither cable is coming into contact with any belts. Belts spin at high speeds under the engine bay and can damage battery cables. Place the battery back in the car.

Make sure not to let the new cables come into contact with the battery terminals as you return it, as that could result in you receiving a shock. If the terminals on the battery appear to be oxidized or rusted, use a steel tooth brush to clean off the connection area before you place the battery back into the car. Be sure you placed the battery back in the same way it was before you took it out, so the positive terminal is closer to the positive cable, and the negative terminal is closer to the negative cable.

Connect the positive battery cable to the battery. You may want to purchase a corrosion inhibitor that you can put on the battery terminal prior to connecting the new cable. Squeeze the inhibitor onto the terminal, then slide the new positive cable connection over it. Make sure the cable is connected firmly. It if jostles loose while you are driving the car will turn off.
