You can Select Your Vehicle to check if 12157287 fits your vehicle.

Periodically inspect the entire length of each battery cable for damage, cracked or burned insulation and corrosion. Poor battery cable connections can cause starting problems and decreased engine performance. Check the cable-to-terminal connections at the ends of the cables for cracks, loose wire strands and corrosion. The presence of white, fluffy deposits under the insulation at the cable terminal connection is a sign the cable is corroded and should be replaced. Check the terminals for distortion, missing mounting bolts or nuts and corrosion. If only the positive cable is to be replaced, be sure to disconnect the negative cable from the battery first. Caution: On models equipped with a Delco Loe II audio system, disable the anti-theft feature before disconnecting the battery. Disconnect and remove the cable(s) from the vehicle. Make sure the replacement cable(s) is the same length and diameter. Clean the threads of the starter or ground connection with a wire brush to remove rust and corrosion. Apply a light coat of petroleum jelly to the threads to ease installation and prevent future corrosion. Inspect the connections frequently to make sure they are clean and tight. Attach the cable(s) to the starter or ground connection and tighten the mounting nut(s) securely. Before connecting the new cable(s) to the battery, make sure they reach the terminals without having to be stretched. Connect the positive cable first, followed by the negative cable. Tighten the nuts and apply a thin coat of petroleum jelly to the terminal and cable connection.
