A necessary component in the repair is a complete set of high-quality tools. Quality is the most important requirement here, as a cheap tool can become very expensive because it jumps off and destroys expensive parts in the process. A good quality tool can be used for a long time and ultimately compensates for the cost of acquiring it. The basis of the tool kit is a set of wrenches that can be installed in any well-accessible place. The ring wrench set is an excellent addition to the previous set, especially in the case of tight bolts and nuts or when there is not enough space. To reduce costs, you can also use a set of combination wrenches, at one end of which there is a regular open-end wrench, and at the other a box wrench of the same size. The figure below shows what these keys look like.

You will also need a socket set. They can be used to loosen deep seat bolts and nuts. The next required item is a set of Phillips screwdrivers, pliers and a hammer. In addition to the basic kit, you can add several special tools that in most cases provide invaluable assistance, especially if certain work needs to be done quite often. This saves a lot of time. As an example, we can mention an impact screwdriver, without which it is hardly possible to loosen industrially tightened Phillips bolts without damaging them. It can, of course, be used to tighten tight fittings. Also, circlip pliers are often needed to secure gears, shafts and similar parts, and it is quite difficult to remove the circlips with a conventional screwdriver. There are two types of circlip pliers, one for outer rings and one for inner rings. They have straight or curved grips. One of the most useful tools is a torque wrench, a type of wrench that can be adjusted so that it will turn freely when a certain torque is reached. There are similar wrenches with a dial indicator that indicates the torque reached. Tightening torques are specified in any modern repair manual, so that complex groups of elements, such as a cylinder head, can be tightened without the risk of damage due to overtightening.
The more modern the car model, the more tools are required to keep the car in a ready-to-use condition. Unfortunately, some specific jobs cannot be done without the use of special equipment, and which can greatly undermine your budget if not entrusted to specialists. There are also simple jobs that are also best left to professionals. While a multimeter is a great help, in the wrong hands it can cause major damage to electrical equipment.
Although this manual shows how various jobs can be done without special tools (when it is not required), However, it is better to work with a special tool. This is especially worth doing if the car has high mileage. Various parts can also be removed and installed using improvised methods and tools without the risk of damaging them. However, the use of a special tool prescribed by the company will in any case save a lot of time and nerves.
