I can replace a flat fine, I understand how to use a jack and a torque wrench and have tangential knowledge regarding a little bit of mechanical engineering from a previous job.
The feeling I get is that auto work goes much much deeper though, and I am interested in resources that offer that knowledge.
If you know not only what a torque wrench is, but how to use it properly you will likely have no trouble changing brake pads.
Full engine rebuilds, or even troubleshooting intermittent CANbus issues, sure. But basic maintenance like brake pads or changing out a failed alternator just require basic hand tools and some minor knowledge you can get from youtube.
Thanks!
You're right... it does go a lot deeper. If you're in the USA, your local community college might have classes. Consider starting with some formal instruction. The problem with YouTube is that you (the one lacking knowledge) has to decide whether the YouTuber knows what they're doing. There's a lot of great stuff on YouTube, but there's plenty of wrong and unsafe stuff too.
Also, avoid super cheap tools for the tools that interface with screws, nuts, and bolts, like wrenches, sockets, screwdrivers, hex and torx drivers. Cheap tools make it wasier to damage screw heads and bolts.
