Trouble Ticket Help Requests for DTC P0128
Help Request Posted
2017 Cadillac XT5 3.6L Steering VIN: 1GYKNBRS6H
P0128: Coolant temp. P0128 Seems to need a thermostat- the thermostat seems to be rather involved job- any precautions, advice or any other information on doing this job? Do I need other items- gaskets, orings etc to compete the job? Thanks
