Message Previous owner changed the timing belt ( twin turbo ),
water pump, idler pulley, and various seals
at 120k...but not the auto-tensioner ( it still met tension specs and was changed back at 60k ). Don't want to do it all over
just for the auto-tensioner ( currently running fine ). Do these have a mile life ?
Do they give any warning signs when they start to go bad?
Can you visually check their positioning to render a verdict?
What do you have to remove to be able to see its deflection?
