Пять признаков износа ремня ГРМ.

There are five signs that our timing belt sends us to tell us that it is worn out, and that we should not ignore: let's see what they are. Before inspecting it, we must remove the timing belt cover, although sometimes it will be necessary to remove some engine components. 1) The timing belt is too tight and could skip some gears and lose timing: the engine will run unevenly, there will be difficulty starting, loss of power, and increased fuel consumption. We will need to check the timing marks and that the tensioner is at the right degree of tension. 2) Leaks under the timing belt cover indicate that technical fluids have deposited on the belt, which can slip or break. We will need to check all the seals before changing the belt. 3) Strange sounds coming from the belt, which occur if the belt is very worn, misaligned, or if the bearing is stuck. The noise depends directly on the engine's rotation speed. 4) Damaged belt such as fraying, cracking, tooth wear, or fiber breakage. It must be replaced even if only the edge is worn. Check the distribution mechanism and, if necessary, install new components. 5) Incorrect positioning of the belt. It is indicated by the axial movement of the belt relative to the pulley. The reason may be a poorly installed component or a fault in the tensioner pulley. Incorrect positioning of the belt generates irregular wear and tear. The timing belt replacement is usually done at 50/100,000 km or 5 years, depending on which of the two conditions occurs first.
