Please Use a Service Manual.

I will bet you that lots of people on these internet web forums, have probably never heard of a factory mainenance manual, or a Motors, Chiltons, manual.
People that all that they know is from what a computer screen tells them.
Different generation of modern people, that don't know what they are doing, repair wise, on a automobile.
And our infastructure in America is falling apart, with only a few knowing how to repair things anymore.
Were all doomed.
