I am told that there should be a tensioner
bolt head and it has a very long
thread which screws into the backside of the center
bolt / nut that is 90 degrees of the center
bolt / nut but I can not find it.
You should also pay attention to such possible malfunctions and defects as unreliable
thread for cylinder
head bolts, thermostat flows, high demands on the quality of petrol (not for TU versions), lower average lifespan in comparison with its predecessor.
