All O2 sensors are threaded into the exhaust system at various points.
From what I understand, you have to diconnect the exhaust system on the side that the starter motor is located on. To reassemble you have to replace the exhaust gasket with a new one. If you are replacing the starter, there is a GM starter that is a direct replacement for the Isuzu starter and costs quite a bit less.
