How do you replace the alternator on a 98 Oldsmobile Cutlass?
Remove serpentine belt, remove three bolts ,an 2 wires. The alternator will pull up off the motor to remove. Put new alternator in replace bolts, replace wires, an replace the serpentine belt..
Not that difficult - everything is on the top of the engine. Take the serpentine belt off first, disconnect the wires and attach them to the new alternator in order. Then take the bolts out (they are obvious) and change the alternator - put the belt back on - that's usually the hardest part and your done.
The 1998 General Motors/Oldsmobile Cutlass came equipped with the 3100 V6. This vehicle has multiple O2 sensors located up and downstream of the catalytic converter. Removal and replacement of the O2 sensors requires first disconnected their wiring harnesses. Then they can be removed from the exhaust piping by a wrench. If the mileage is sufficiently high enough it is advisable to replace them altogether.
