S-10 O2 Sensor

After the "service engine soon" light came on in the S-10 and finding the P0139 code with the scan gauge, the O2 sensor was replaced.

The old one was removed and the new one was spliced on using the included kit.

S-10 Alternator

We changed the alternator in the truck.

Process: As the Chilton book says:

Remove negative battery cable.
Remove alternative.
Install new alternator.
