If a coolant hose bursts while driving, temporarily seal the leak with adhesive tape. To be on the safe side, slightly loosen the radiator cap: then the operating...

Air filter (air intake noise damper)
In order to extend the service life of the engine, the intake air - before it combines with the fuel to form a flammable mixture - passes through a special filter...

Cleaning and replacing the air filter insert
You should clean the filter element and the place where it is installed - the foam dust collector in the air filter box - at least once a year and change it at least...
