every car is different. common sense is to
have a repair manual, for every car you own.
It will show what the job entails, and from
there you can decide if you trust yourself,
or not. It's always worth research for every
reason. If you can't do it, you bring your car
to the mechanic and tell them what the problem
is and what you can't do. That way they can't
get away with ripping you off.
Everybody has an ego. Every mechanic is not
going to want you to be better at his job than
him. Chances are, if you tell him what's wrong,
and admit you can't do it, his ego will kick in,
and he will try to prove his skillfulness by making
it an easy job.
Common sense.
