Use a 10mm ratchet attachment to remove the battery from the vehicle. Negative terminal first, then positive. Be careful not to cause an arc between the two terminals as intense pain will result.
Remove the plastic plate that the battery sits in. 2. Using the 10mm attachment again, remove the 6 bolts that hold the passenger side front splash guard from underneath the front bumper. 3. From underneath the vehicle, locate the oil filter. Look above oil filter and you will see the starter. Locate the bottom 14 mm bolt that attaches the lower portion of the starter to the engine. The bolt drives from left to right. The starter is mounted toward the front of the vehicle and underneath the intake manifold. Still cant find it?
Follow the cable that leads from the positive battery terminal. It ends at the starter. Not sure you have the right bolt? Stick your 14mm attachment on it with your fingers and see if it fits on properly
