The CHILTON 2011 LABOR GUIDE MANUALS features new models and new labor operations in order to stay current with new technologies. In addition, Chilton's editors have split up larger model groups into smaller ones so that users can find vehicles quicker. The 2011 edition provides repair times for 1981-2011 import and domestic vehicles. Chilton's editors consider warranty times, component locations, component type, the environment in which technicians work, the training they receive, and the tools they use when calculating a labor time. To allow for vehicle age, operating conditions, and type of service, the Chilton 2011 Labor Guide provides standard and severe service times, plus OEM warranty times. Vehicle makes and models conform to current Automotive Aftermarket Industry Association (AAIA) standards.
