I just replaced the starter motor on my 1990 4 cylinder engine Chevy Lumina. The starter is located in front of the oil pan. It was reachable and can be seen from under the front of the car a little to the right. You have to remove a three bolt attached plastic part by the oil pan to be able to get to one of the starter motor bolts. Good luck.
