Ed gets the gold star..... there's only so much information that they can
put in to an owners manual... and any owners manual I have ever seen only
ever covers roadside emergencies.....
"Next we'll see "My owners manual doesn't tell me how to change my spark
plugs" or "My owners manual doesn't tell me how to overhaul my
differential".... as the complaint of the day.
All of these manuals assume previous knowledge for many things...... In my
job, there are many times when it is important to consiuder what the manual
"doesn't" say along with what it does.... But if we are to do mechanical
things, it is very important that we have some sort of a skill set in place
to begin with. If not, it is far better to find someone knowledgeable help
teach us the rudimentary skills and we can build from that.
For the OP.... community colleges, auto clubs, high schools and even
retailers sometimes offer "auto maintenance for beginners" kinds of courses.
I heartily recommend taking something like this in order to familiarize ones
self with cars in general before they get carried away with wrenches.
A couple of years back, a friend had her son (late teens) change the oil in
her Mazda MPV.... when she tried to go to work the next morning, the car
wouldn't move and the engine was 5 litres overfull.... The boy had drained
the transmission pan by mistake..... Sadly, a "maintenance for neophytes"
type class will not teach us to look twice, act once.
