There is a timing belt between the shafts (camshaft and crankshaft) in the car engine. With its help, movement is transferred from one shaft to another, and the belt wears out. When should you change it?
The timing belt drives the camshaft, which in turn opens and closes the valves in the desired sequence. Thus, either fuel is injected into the working area, or exhaust gases are discharged.
When the timing belt needs to be changed
The timing belt is subjected to quite powerful forces, so it wears out. How do you know after what period of time it needs to be replaced? If a new one is not installed in time, the old one may burst, the valves in the engine may be bent. This entails quite expensive repairs, which will hurt the car owner's wallet. Although the engines in modern cars are insured against such a nuisance, all the same, problems cannot be avoided.
It is better to change the timing belt, which still has a margin of safety, than to repair the engine later.
The timing belt must be replaced after 40-50 thousand kilometers, if the car is of the domestic auto industry. If the car was purchased in the salon, new, then during the maintenance everything that is needed in the auto repair shop will be replaced on the basis of the warranty card. If the car is of foreign production, the critical mileage for the timing is much higher, about 70 thousand kilometers. Despite the fact that manufacturers declare a certain number of kilometers of mileage for the need to replace the timing, it is better to divide this figure in half for domestic cars, and subtract 40% of the declared figure for imported ones. It will be safer and safer this way.
If the car is purchased from hands, that is, already with mileage, you need to ask the owner when this belt changed, and whether it ever changed at all. If this is not known, you need to build on the run. If you exceed 30 thousand km, you just need to change this spare part so as not to risk it. Repair will cost more than replacement. If you buy a foreign car, then again look at the mileage. Are there 50-60 thousand km? Change definitely.
What should be the timing belt
Do not forget about the adage that the miser pays twice.
It is best to put this spare part in the salon, and the one that the plant itself installs on new cars. In a workshop around the corner, they can offer to save money by installing another belt, but this is obviously a losing one, since it will last 10 thousand km at best. And you will have to change it again. The best option is the original timing belt for a particular car brand. A quick failure of the timing belt is due to the fact that in the conditions of Russian winters in parking lots it is necessary to warm up the engine for 15 minutes, all this time the speedometer does not change readings, but wear is in full swing. And it means that you should not save on this detail.
