I maintain an account with alldata...It is the next best thing to having a
factory service manual

Chilton also has one and it is $20 per vehicle

I use Autozone's repair info. frequently.  As Pete says, it isn't as
comprehensive in some areas as say Alldata or a factory service manual,
but has enough for most people to feel confident about doing their own
repairs. The Autozone site doesn't go much past the year 2000, and
doesn't cover too many cars in certain years, but it is useful.  Sort
of a combination Chilton's/Haynes and a bit of factory put together.

Best of all, it's free.  Works for me, LOL.

Why don't you just get him to grab a for real factory service manual/s
for the car? They'll be far cheaper in the long run than Alldata, and
much more convenient.

This place has them by the ton... If your car's manuals come in multiple
volumes, be sure to get them all.

Alldata is good, especially if your in a shop environment working on
different stuff all the time. For your own, get the for real printed
manuals... they'll save you a bundle in the life of the car, don't tie
you to your computer, and they're a good selling feature if and when you
ever sell the car.

Should the car end up being totaled, ripped or scrapped, manuals sell
well on eBay. You can't loose.

If you ever buy a new car, get the dealer to throw them in as part of
the deal. It's not a common request, and they'll hem and haw, but can
get them through their parts department just like any other accessory.

By Mitchell On-line- 9.99 per car per week.  At my last shop we had
Mitchell-on-line, and I was pleased with it. but the dealership has Subaru
tech only and doesn't see the need for the expense of the complete service,
so I am allowed to charge enough to the account for diagnostics for a
specific car when needed. Mostly I use it for wire schematics; and in a few
cases they were easier to dig through then the OEM stuff for the Subies.
