On some vehicles, it may be necessary to remove the exhaust pipe(s) or frame crossmember to gain access to the starter. In extreme cases it may even be necessary to unbolt the mounts and raise the engine slightly to get the starter out. Detach the negative cable from the battery. Caution: On models equipped with the Theftlock audio system, be sure the lockout feature is turned off before performing any procedure which requires disconnecting the battery. Remove the air cleaner and duct assembly, as necessary. On the 3800, remove the upper mounting bracket, the cooling fan, and the oil cooler lines from the radiator. Raise the vehicle and support it firmly on jackstands. On 3.4 liter, 3800, and 3100 V6 engines with 4T60-E/4T65-E transaxles, remove the flywheel inspection cover. Remove the oil filter splash shield, if necessary. On the 3800, remove the engine harness retainers and position the harness away from the starter. Clearly label, then detach the electrical connectors from the starter. Remove the mounting bolts and nuts (if equipped), then remove the starter. Note the location of any shims used. Installation is the reverse of removal.

If the starter motor does not turn at all, check that the shift lever is in Neutral or Park (automatic transmission) or that the clutch pedal is depressed (manual transmission). Ensure that the battery is charged and that all cables, both at the battery and starter solenoid terminals, are clean and secure.
