I appreciate instructor feedback about Automotive Service 5E and/or Automotive Engines 7E. If you find errors, these can often be corrected prior to a reprint after books in stock have become exhausted. I also use instructor comments and suggestions as I revise the text for a new edition. These books are also available in electronic form, where changes can be made immediately. 


I have many reviewers for each text revision.  If you would like to be a reviewer, please let me know.


You can send me an e-mail at TimGilles@TimGilles.com
