How do i replace a 1987 mercury cougars starter and where is it located

Hi Devon, Disconnect the battery and then follow the heavy positive cable to the starter motor. Remove the securing nut which hols the same cable and the smaller cable to the solenoid. You may also find a thin cable which is an earth connection. Do not mix these two cables when reassembling. Remove the mounting bolts and once done remove the starter motor, fit in new unit and assemble in the opposite as disassembly. Regards John

It's on passenger side of engine two wires and two bolts
