Hi my tensioner seems to be moving far too much and the engine sounds louder than normal. Can you tighten these? Its a 2012 leg Dsl 2.0 i have video but this site wont allow me upload. Thanks 

Any help be great, all mechanics closed here in Ireland due to covid lockdown. Please!!!! Ive still to get to work in early hours of morn and dont wanna break down. Thanks 

Unfortunately I've never seen under the bonnet of a diesel subaru but that doesn't seem right to have that amount  of movement to me .

Is that just a auxiliary belt tensioner ?

If so you could try to remove the belt completely,  just to see if the noise goes away and pin point where the noise is definitely coming from .

Unfortunately I don't know anything about that type of tensioner but it does appear to be spring loaded ?

Maybe @Mr B can help ?

Thanks savage bulldogs yeahits drive belt for AC, steering, alternator etc. I think it is the spring thats gone. Trying to get replacement part but its not easily available off the shelf, not locally anyway.
