Book structure
Each section consists of the following parts: theory, maintenance, repair.
Theory.
Contains a description of the arrangement of nodes, parts, mechanisms and their interaction. Here you will find
Technical dictionary.
It explains the basic terms and definitions, gives brief characteristics, purpose and operation of vehicle components and systems.
Below is a sample design «technical dictionary».
Maintenance.
All the necessary work is presented in detail, step by step.
Work symbols characterize the time spent on each action, the degree of complexity and risk in carrying out work for personnel and the environment. Illustrations make the material more accessible and facilitate the work.
Repair.
Detailed description of repair operations. Practical advice will help you when replacing parts and troubleshooting problems. This section lists possible malfunctions, their causes and solutions.
The table of contents at the beginning of each section will help you quickly find the information you need.
The illustrations given in the book give a visual representation of the design of components and assemblies; sometimes they determine the sequence of work or the order and directions of removing and installing parts when performing maintenance and repair.
The technical dictionary provides information in a concise manner on the basic concepts, purpose and relationships.
TECHNICAL DICTIONARY
The main parts of the engine
Cylinder block. It contains the moving parts of the engine. In most engines, the cylinder block is made of gray cast iron. Auxiliary units, such as a generator and a starter, are also installed on the cylinder block, elements of the ignition system are located.
Cylinder head. Closes the cylinder block from above. It contains the inlet and outlet ports for the air-fuel mixture and exhaust gases, valve seats, bearings and valve guides, threaded holes for spark plugs, channels for the cooling system and combustion chambers. The gasket between the mating surfaces of the block and the block head prevents coolant and air from entering the cylinders.
SEQUENCE OF WORK
1. Remove the intake manifold. On vehicles with diesel engines, remove the suction pipe. On vehicles with all engines, disconnect the electrical wiring.
2. Turn away six bolts of fastening of a cover of a head of the block of cylinders and carefully remove it. If the cap is firmly attached to the head, remove it by gently tapping it with your hand or the handle of a hammer
3. To measure compression and check the serviceability of the valves of one of the cylinders, the intake and exhaust valves must be completely closed. To do this, turn the camshaft so that both cams of the first cylinder (in driving direction to the right) were symmetrically in the upper position (it is necessary to follow the marks that determine the TDC) completely closed.
PRACTICAL ADVICE
Compressed air leak
If there is an air leak at any point during compression, the most likely causes are as follows.
Faulty intake manifold or air filter housing (the latter due to a faulty intake valve).
The cap of the radiator or coolant reservoir is open.
The following list of faults, indicating their causes and methods of elimination, will help to detect damage in various vehicle systems.
Subsection «Practical Tips» allows you to quickly and efficiently detect a malfunction and eliminate it.

|
A. The arrow of the coolant temperature gauge is in the red sector
|
1. Insufficient tension of the V-ribbed belt or it is torn
|
Tighten or replace poly V-belt
|
|
2. Too little liquid in the cooling system
|
Add liquid

3. The temperature gauge wire is shorted to "mass"
|
Disconnect the wire from the temperature sensor; the sensor needle should return to zero, otherwise there is a short to "mass"; check the wire from the sensor to the temperature gauge

Maintenance during the warranty period
When operating a new Ford Fiesta, be sure to follow the maintenance intervals prescribed by the manufacturer. First of all, refuse to do the work yourself: even justified claims during the warranty period, Ford will only accept if the maintenance work on your car was carried out by an authorized service center. This provision also applies if you operate a vehicle with an overhauled engine.
Working symbols
Symbol «tree» should remind you to protect the environment. This symbol is placed in all cases where the operations performed or the waste associated with them are harmful to the environment.
the number of wrenches indicates the degree of complexity of the work performed:
1 key - easy work;
2 keys - serious work that requires appropriate effort;
3 keys - hard work.
Hourglass - indicate the approximate time spent on repairs. The risks on the clock correspond to a quarter of an hour; with a fully filled clock, you need to count on an hour of work.
Exclamation point - indicates operations on which the safe operation of your vehicle depends. If you are not sure that you can competently perform these works, do not undertake them! Contact an auto repair shop.
Control symbol - This symbol marks the work on preparing the car for technical inspection. You will save time and money if you carry out the maintenance and service work marked with this pictogram before the due date for the inspection.
This pictogram indicates all maintenance work on your vehicle, which is carried out at service stations. All items correspond to the official lists of maintenance work.
