Ремень ГРМ 127 BOSCH NEXIA DOHC 1.6 (1987949403)

The timing belt is responsible for synchronizing the crankshaft and camshafts. This ensures the exact coincidence of the working cycles of the engine: the valves open and close exactly at those moments that correspond to a particular position of the piston. How to understand that you need to change the timing belt? Visually assess the condition of the belt is not easy in most cars, it is hidden under the casing, and it will not do without disassembly. But if the engine started to run unevenly, this may be one of the true symptoms. Ticking and clicking sounds from under the hood, smoke from the exhaust pipe and oil or coolant leaks from under the casing can also serve as indirect signs. All this does not necessarily indicate the wear of the timing belt, but requires prompt diagnostics in the service.
