Engine diagrams and service manuals are usually available online from specialty websites or forums, or they may be purchased from some auto parts stores. While some websites and forums charge money for a hard copy or a digital download, others may provide picture files of engine diagrams for free.
Websites such as the S10 Forum provide a place for owners of Chevrolet S10 trucks and S10 Blazers to share information with one another. This includes links to other websites that sell hard copies of owner's manuals and diagrams and suggestions for other websites that may provide free diagrams. Searching images on search engines such as Google also yields graphic results of many S10 diagrams, depending on the year the vehicle was made.
