Immediately after purchasing DB9 1936 I was on a quest to find a DB9 Service Manual. I started in the usual fashion by Googling for it. At best, I was lead to sketchy websites and forums where a zillion people had be asking looking for one to download, and usually someone overseas would post a link that wouldn’t work anymore (or worse leads to some site with Spyware).
It’s illegal to post a copy of the PDF of the manual. Aston Martin frowns upon this greatly it appears.
This search did lead me to the ‘legal’ solution to the issue. Aston Martin has a Technical Information website where it publishes EVERYTHING for its cars, old and new. This is really a resource for shops and dealers, but even us lay persons can get in on the action.
You can find it here https://www.astonmartintechinfo.com
Go ahead and create your login account. The account is free, but you’ll soon find the documents you want can only be viewed/downloaded with an active subscription that costs a few $$.
You can enter your VIN number and it will filter down the library to just the relevant items to your car. I did this first to see what is available for my car. The answer is a lot of stuff, from nearly irrelevant minutia to the full on Service Manual.
Convinced I wanted to get access to it, my sweetie Karen gave me a one-day subscription for Christmas. You can get a 1 day, 1 month or 1 year subscription. One day costs 70 British pounds (about a hundred USD). If you are whining about spending a hundred bucks – you bought the wrong kind of car. Think of it as the cost of going and buying a Chilton’s manual. If you have an earlier model DB9, its highly unlikely that anything new will be published, so doing this one time should suffice for a lifetime.
The day I signed up I was fully prepared to download EVERYTHING available in that one day. I sucked down the manuals, service bulletins, checklists, everything. I saved them all in a folder on my computer (my Dropbox folder actually so its backed up and available from my phone, ipad, and PC). Now I have everything I need!
The manuals are NOT written like a Haynes or Chilton DIY guide. They are written for Factory trained technicians and short on some of the advice and finesse that might be needed. I still find it completely helpful to see the instructions, have all the specifications, and diagrams.
