Free Auto Repair DiagramsBelow we provide access to three basic types of diagrams that will help in the troubleshooting and diagnosis of an automotive related problem. Wiring diagrams are one of the most common these days with all the added electronics. The bells and whistles tend to break the most often. Vacuum diagrams are less common but still viable with the controlling of the air conditioning and heating systems on older cars and a few components on newer cars.
Belt diagrams come in handy when replacing the drive belt especially when the old one breaks and falls off and you are left with the job of figuring out how it goes back on. What ever the situation, these three basic diagrams are invaluable when it comes to troubleshooting any car repair.
