Next, you need the most complete set of good tools. Quality is the main law, since a cheap tool can cost more when it breaks or falls off and damages valuable parts. A good tool lasts a long time and pays for itself. The main part of the tool is the wrenches, which can be used anywhere on the car where there is sufficient access. It is advisable to have a set of box wrenches for working with bolts and nuts with high tightening torques or in places where access is difficult.
To save money, you can purchase a set of combination spanners, which have a regular spanner on one side and a spanner of the same size on the other side. Key heads are the best purchase. If the outer diameter of the head is not very large, they can be used to unscrew recessed nuts in places with particularly difficult access.
The necessary tools are a set of Phillips screwdrivers, pliers and a hammer.
Additionally, you also need to have some special tools, which usually provide invaluable assistance when carrying out work that is performed frequently. It saves a lot of time. An example is an impact screwdriver, without which it is difficult to remove Phillips screws that are installed at the factory. This screwdriver can also be used to tighten screws to ensure a tight connection. Snap ring pliers are also required, as quite often transmission gears, shafts and similar parts are secured with circlips. There are two types of these pliers, one for external and the other for internal circlips. They also come with straight or bent legs. The most necessary tool is a torque wrench, which is rotated at a certain tightening torque of the nut or bolt. There are wrenches with a scale on which you can count the tightening torque. Tightening torques are indicated in every modern operating and repair manual, so that the most complex components, such as the cylinder head, are not damaged when tightening the mounting bolts and nuts.
The more complex models become, the more tools are required to ensure the owner maintains the car. Unfortunately, some very special work cannot be carried out at all without special devices, which are very expensive if you do not contact a specialist. And here you need to be especially careful, because there are a number of jobs that are best entrusted to a specialist. For example, a universal tester that allows you to determine a fault in electrical equipment can cause great harm in the wrong hands.
Although this repair manual will tell you how to remove and install certain components without using special tools, it is best to purchase the most common special tool. This pays off when they want to keep the car for a long time.
Various parts can be removed without fear of damage and using recommended, improvised methods and tools. However, in any case, a special tool made and sold by the vehicle manufacturer will save a lot of time (and troubles).
