PREFACE:

Although this book has been written mainly for those who wish to gain an NVQ in motor vehicle work, it is equally suitable for a wide variety of people who are undertaking the City & Guilds, BTEC as well those who just want to know about cars to enable them to undertake their own servicing with a greater degree of confidence. 

It can be used in schools, colleges and garage workshops as each task is being undertaken. It covers the fundamental principles for each system found in the motor vehicle. It is by no means exhaustive, but it does allow the student to take simple steps in understanding how each system works. The NVQ qualification is not as daunting as many people think.

 The main problem seems to be in the gaining of evidence and the assembling of a portfolio, so, with this in mind, there are a number of exercises at the end of each section for the student to complete. 

The evidence required by the NVQ assessor from the student will be gained gradually and built into a student portfolio. Each completed job sheet (suitably signed after the job has been checked) should show evidence of what you have done, how you did it and that it was completed to a satisfactory standard. 

When the student feels confident enough to complete the task alone then he or she may request an assessment. Examples of assessments are given in the book to show what might be required by the assessor. 

The text has a number of words and sentences that are highlighted when they first appear in the text. These are mostly key words that will help the student to remember what is essential from the text. No matter how much the student ‘waffles’ when answering questions, unless he or she understands the subject and uses the key words, it will be very difficult for the assessor to give marks.

 Remember the key words and you will be half-way there. Some of the words used are specific to the motor vehicle and to the NVQ. We have tried to explain those relating to the motor vehicle in the text and those relating to the NVQ in a glossary at the end of the book. There are a number of practical assignments and learning tasks in each chapter. 

If these are undertaken in a realistic way, they will enable the student to complete the task repeatedly, up to an acceptable standard, without supervision, which is the requirement of the NVQ.

 The workshop job sheet should contain all the elements of the performance criteria as requested in the NVQ. They should be signed by both the person undertaking the task (you) and the assessor/supervisor to say the task has been completed satisfactorily.

 The illustrations have been selected to give the maximum amount of support when learning about new topics.

 We advise students to attempt the learning tasks when they have completed the related section of their training and education. 

This book is based on many years of teaching and helping students and apprentices who have gone on to become successful and valued mechanics.

 Some of them have become owners of their own motor vehicle workshops, each in turn has appreciated the training that was given to them in their early years.

 Our hope is that this book will enable a wider variety of people to achieve their hopes and ambitions.

In order to take account of feedback from practicing teachers and to allow for developments in technology, education and training this 2nd edition includes coverage of developments such as; variable value timing, on board diagnostics, computer controlled systems etc.

 maintenance aspects are covered and a range of learning tasks and self assessment question is included.
