A6 V6-12V 97' - Rattle from front end of engine resolved.. |
|
|
Hello
Just to put out some information to people that are hearing lots of rattle
at start-up of the V6-12V engine..
After listening to the bad sounds for too long I finally got to do the
work.. I dismounted the serpentine belt first to rule out the involved
parts there.. However there was no change to the bad sounds..
I therefore dismounted the covers for the timing belt and found the
cause.. A slack timer-belt... adjusting the timing belt tensioner made the
horrible sounds disappear..
I can't blame any other than myself, as I changed the timing belt this
spring.. Seems like the bolt-tension/ friction barely overcome the forces
from the running timing belt.. It even got loose again just after having
put on the covers again, so I had to redo the work..
A sunshine story in mid winter.. :-)

Maybe when you changed the timing belt, you didn't change the tensioners?
Always worth doing.... |

Changed tensioner, timing belt roller, water pump and thermostat.. So all |
were done by the book..
However I got a bit confused about if the tensioner should be rotated
clockwise or anti clockwise to tension the belt..
There seem to be a difference between the 12V and the 24V as the later
have an extra spring loaded tensioner system..
This time I chose to rotate the tensioner clockwise..
