Replacement schedule The timing chain drive on the Opel should be changed after 150,000 km. Although the manufacturer does not regulate the frequency of replacement, experts recommend this interval. But the chain can work out its resource a little earlier. Therefore, it is very important to carry out diagnostic procedures from time to time. If you do not do this, you can miss the moment when the chain stretches. And this can happen earlier than expected. There may be several reasons for this. Firstly, the service life of the chain drive can be significantly reduced if the car is constantly subjected to increased loads, if a trailer is often used, for example. Using the car mainly in the city also does not contribute to an increase in the service life of the chain. Some drivers practice aggressive driving, and this also wears out the chain ahead of time. Bad oil is another reason for premature wear of the chain drive. Oil in general requires special attention. Use only high-quality motor oil in your cars, and also monitor its level. The chain is lubricated through a whole system of injectors. Its quality must be very good. In addition, you could simply buy a low-quality consumable, and it worked out ahead of time. If the chain is worn out, then this can be determined both by ear and visually. If the engine has stopped making a pleasant rustling sound when running, if an unusual noise and grinding sound is heard during engine operation, then it is time to think about the condition of the chain drive. As a rule, this is the reason why drivers decide to look under the hood of their iron horse. If there are chips on the chain, then it is time to replace it. If the usual tension of the transmission no longer gives the desired results, this also indicates the need to replace the chain. So, if you have determined that the chain drive needs to be replaced and decided to do the replacement yourself, first of all, prepare everything you need. Go to the store and buy a new chain there. In addition to it, you need to buy related consumables, such as a tensioner and dampers. You should also buy a set of oil seals. Experts recommend changing the gears along with the chain. But you should only do this if they are really worn out. They may still be quite suitable for use. If you don’t really trust your competence, then it’s better to invite a specialist who will carry out the necessary diagnostics and tell you whether only the chain needs to be changed or the gears also need to be replaced. #viktorgarage #opel #timing
