Jeep Grand CherokeeWhenever you turn the key to the start position you expect the car engine to turn over and start. When it doesn't it is usually a dead battery which can be frustrating enough. However, on occasion it is not the battery but another part of the starting system. The starting system consists of the battery, starter relay, starter motor and the wiring connecting them together. This article deals with the starter motor assembly portion of the starting system. If any part of the starter motor fails, including the solenoid, the entire assembly must be replaced. The starter motor is located on the lower part of the engine, next to the transmission. The following steps will take you through the process of replacing the starter motor assembly.
