| − | #Disconnect the battery. Use an appropriate sized hand or socket wrench to loosen the nut that secures the cable on the negative terminal on the battery. You don’t need to remove the nut completely; once its loose simply slide the cable up and off the terminal. Tuck the cable to the side of the battery to ensure it won’t touch the terminal as you work.<ref>http://shop.advanceautoparts.com/o/article-car-starter-replacement</ref> | + | #Disconnect the battery.

| − | #Compare the new starter to the old one. Place the old starter side by side with the new one on a table and compare them for similarities and differences. The two should look nearly identical and the holes for the starter retainer bolts should be in the exact same place. The starter solenoid may have four terminals instead of two, but that won’t be an issue.<ref>https://www.pepboys.com/car_care_corner/do_it_yourself_guides/haynes_tech_tips_starter_replacement/</ref> | + | #Compare the new starter to the old one.
