Progress in car construction in recent years has resulted in the reduction or elimination of many control and regulatory activities, which systematic performance was previously necessary. For example, there is no longer any need for constant control and adjustment of the ignition, or idle adjustment. A greater number of elements that work long and stably, which include e.g.. electronic ignition systems and electronically controlled injection systems, contributed to reducing the frequency of repairs. On the other hand, checking electronic components, which replaced the more unreliable mechanical parts requires the use of expensive diagnostic equipment, often intended only for a given type of vehicle. Their purchase is usually unprofitable for an amateur mechanic.
Because the car is getting more and more technically complex, it can no longer be used consciously, whether to work with it without specialist instructions. This applies not only to amateur mechanics, but also professionals, even when it comes to replacing the friction inserts, muffler, shock absorbers, removal of signs of corrosion or the like, used to be routine maintenance and repair activities. Users often subject their car to modernization procedures (tuning), they install additional equipment, etc.. However, every DIY enthusiast must be aware, that you don't become a car mechanic just because of a book. Therefore, only these jobs can be undertaken, which we can actually cope with. This especially applies to repairs that affect the safety of driving, which we pay special attention to. In case of any doubts, it is recommended to have the repair done by a specialist workshop.
Accusations are sometimes raised by interested bodies, that self-repairs have a negative effect on road safety. The opposite is apparent from my contacts with amateur mechanics. The user who maintains and repairs his vehicle tries very hard, that his car is safe and tidy. It is not just about cutting expenses, As a rule, communing with modern technology gives him pleasure.
It's always a good idea to check this page before getting started. This will allow the extent and difficulty of the repair to be assessed. Moreover, it will be known, what spare parts to purchase and possibly, what special tools will be required. Most threaded connections have a tightening torque. In cases that absolutely require the use of a torque wrench (cylinder head, driveshafts etc.) the torque values are shown in bold (it is advisable to tighten all bolts and nuts with a torque wrench).
Even a well-prepared amateur mechanic who repairs his car on his own should remember, that the skilled worker has more practice, and thanks to training and exchange of experience, he is better versed in the latest technology. Therefore, to monitor and maintain the safety of your vehicle, you should visit authorized service stations regularly. It was impossible to cover all the topical technical issues. But I do hope so, that the choice made with regard to repairs, service and care provides answers to most of the problems that arise. Because there are constant technical and technological changes in the production and servicing of cars (improvement of the structure, other consumables, new replacements etc.), it may happen, that the descriptions published in the book are not fully up-to-date. Therefore, informed users and amateur mechanics are advised to constantly observe the changes introduced by the vehicle manufacturer.
