heating, ventilation, and air conditioning systems. The book focuses on the generic theory that underlies the operation, diagnosis, and repair of the units and subassemblies found in the many makes and types of vehicles students will likely encounter on the job. Formatted to better meet the learning needs of today's technical trade readers, it visually supports concepts covered throughout, and includes many practical shop tips that guide students through important problem-solving procedures they'll need on the job. New content for this updated edition includes new SAE J-standards and expanded information on antifreezes and coolants.
