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.. :-)
