Chilton has added so much to its labor guide manual that we?ve had to put it in two volumes! We?ve added hundreds of new labor operations? including maintenance services and electronic system diagnosis?to the Chilton 2006 Domestic Labor Guide manual. All labor times for 1981 through 2006 domestic vehicles consider the real world environment in which technicians work: worn, rusted or dirty components, being serviced with tools commonly used in the aftermarket. Chilton labor times are accepted by most insurance and extended warranty companies. Vehicle makes and models conform to current Automotive Aftermarket Industry Association standards.
