How large are the files and how will the download work?

The PDF files vary from 5MB to a maximum of about 1000 MB. The email you receive will contain a link that will redirect you to a file sharing called Send-space. This link will automatically start the download for your desired manual.

How will I open the PDF manual?

All of our manuals are PDF files that will open with Adobe Reader. 95% of computers come with this program already installed. If your computer does not have this software, it can be downloaded for free at: http://get.adobe.com/reader/

How will I be able to browse through the manual?

Almost all of our manuals contain a very easy-to-follow index. In the case that you have purchased a manual without an index, all manuals are fully searchable. This means that holding Ctrl and pressing “F” will open a search function in Adobe Reader, you can then search the entire manual for any specified word or phrase.

Are your service manuals printed by the manufacturer of the vehicle or by an aftermarket company like Clymer or Haynes?

Our manuals are all OEM factory service manuals; they have been written and printed by the original manufacturer of the vehicle itself.
