CAUTION:
{
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you
can be seriously injured. Do your own
maintenance work only if you have the
required know-how and the proper tools and
equipment for the job. If you have any doubt,
see your GM Goodwrench
qualified technician do the work.
Some maintenance services can be complex. So,
unless you are technically qualified and have the
necessary equipment, you should have your GM
®
Goodwrench dealer do these jobs.
When you go to your GM Goodwrench
service needs, you will know that GM-trained and
supported service technicians will perform the work
using genuine GM parts.
