Belt Tensioner Assembly (CRD)

[TPC]

I know there are plenty of threads about belt tensioners but there is some advising to use aftermarket and some say to use genuine.
I am assuming mine is stuffed as I have a high pitch squeal coming from that area on idle that disappears when I accelerate so am planning to change it.

Who has changed one on a CRD and what did they use, genuine or aftermarket and where is the best place to buy?

Being mechanically challenged should I change it myself or leave it to a mechanic?

I had aftermarket fitted and it shit it's self 4 weeks after left me stranded for the weekend. Fitted genuine and it lasted 2 years and many water crossing etc no dramas. Just my experience .

I had a similar noise that went away with some revs ended up being the alternator clutch pulley.

I replaced mine using a aftermarket one, was on there for maybe a year and didn't have any issues.

TD did you replace that?
If so what sort of $ was it and did you do it yourself?

I am not certain it is the tensioner, could be coming from the alternator.

Looks like the general conscientious is go genuine.

Ended up snapping the alternator shaft on the way home from the Murray
Replaced with an OE alternator.
The noise was ever so slight you wouldnt think twice about it.
BUT 100ks later,, it went
