The internet cops have pretty much shut down most sites that offered
online manuals.  If you don't want to buy a manual, but still insist on
doing the "simple" things on your car then go see if your local library
has a manual to cover your make and model year.

$30 for a manual is going to be the cheapest expense you will encure in
your goal of learning how to maintain your car.  Like was mentioned in
your other post Don't skimp on the tools, buy something good.  Dont buy
something from the "lucky star tool company" you'll see at the local
flea markets.

Snow...

www.autozone.com is pretty good sometimes.

Look on Amazon.com and E-bay.
   A lot of times you can find a good used manual pretty cheap.  It's not
like you need a "virgin" one... because you're just gonna put your greasy
fingers all over it anyway!  >;-}

Library.
I get my books from the library.  I go online to the library's website
and do a title or subject search of all the area's libraries.  I have
them send the books to my local branch (6 blocks away), they email when
they are in, and I go get them - sometimes walk there and back.
Yesterday I picked up a Haynes and Motors for my son's Dodge.
I renew them online if I need more time.

You might want to just change your mind.  Repairing your own car will save
you $1000 a year or maybe more.  Some factory manuals are very expensive and
well worth it.  Manuals you can buy in the store are $30, but they're not
very good.  It kind of depends on what kind of car you have.

Some GM shop manauls are very cheap.  If you're lazy, you can look at them
on ebay and see which ones are the cheap ones.

The public library will lend them out to you for the cost of getting a
membership card ... usually that is free.
