Re: Noise from Cam Belt Tensioner 156 V6
The tensioners are self adjusting, so if it is starting to tick then the bearing is starting to go.
It may last for quite a long time like it is but do you want t take the risk? Don`t panic too much, if it has just started then you should be ok for few thousand miles yet but don`t hang about for too long.
If you are changing the tensioner then you have to change the belt really. It depends on how recent the previous change was as to whether the idlers should be changed as well, all though are you sure it is the tensioner and not an idler that is ticking? See - best to change the lot and feel safe and you can also check out the water pump whilst you are at it.
