This text covers all the mandatory and popular optional units of the IMI Technical Certificates and NVQ Level 1 & 2 syllabus, from health and safety regulations to fault finding and replacing components. Fully updated, it also has vehicle maintenance procedures integrated throughout, making it the indispensable first classroom and workshop text for all students of motor vehicle engineering, apprentices and keen amateurs. The text is made accessible to all levels of ability through its clear, logical approach, excellent illustrations and step-by-step development of theory and practice. There is guidance on preparing portfolios of evidence, and practical exercises are included to demonstrate actual workshop practice.
