I have a wierd noise in the of the motor, it appears to be comming from
the belt tensioner ( not the chain tensioner).
I changed the fan and clutch, the tensioner pulley, and the shock
absorber. The shock absorber is constantly in motion
an becomes very hot, the new one diminished the noise, but still got
hot. Using a mechanics stethascope I could only find an increase in
sound on the area of the tensioner-not the motor itself. I have not yet
checked the tensioner for a possible loose socket head bolt.(100nm).
Flaw in any of the belt driven accessories (sufficient for one of them
to bind) or even a bad idler wheel bearing can result in the tensioner
arm jittering and if it jitters, the shock will quickly wear out. This
is NOT likely to be caused by the socket head bolt - if it becomes
loose, the arm will cock and the idler will NOT be aliggned with the
belt (will be several degrees off). This seldom causes the arm to jitter
or advance shock failure.
