Cambelt noise/whine after new kit fitted

[benwalk15]

So I’ve fitted a new INA cam belt kit (belt, tensioner, w/pump, idler) to my 2015 Berlingo hdi (DV6ETED) and it’s now got a distinct “whine” noise especially when it has warmed up, which follows the engine revs

Have run without the aux belt and definitely still there.

All bolts torqued to correct spec and the tensioner is bang on where it should be (I think!? - see pic!)

Anyone experienced this? Have I got to take it all apart again to reduce tension on the belt until the noise stops?

Sounds to me as if its a little too tight , but it does look as if you've got it right in the photo.

Someone else may know better.

The tensioner is automatic and it's set up correctly.
Could be just the newness of the components.
Keep an eye on the coolant level once the air pockets have completely purged(mine took about 200 miles to settle down completely)

Thank you both for your input.

I now have a horrible feeling that although I set the tensioner up properly (bang on centre), there is a small chance I turned the tensioner the wrong way with the HEX key and therefore the spring isn't doing its job.

Will be stripping it down again later to check it all thoroughly and not starting it again until I have. 

I wish they'd made it easier to get to the bloody thing without taking the arch liner/engine mount/crank pully off, but I guess that's just modern engines for you!!!

Will update with my findings.

Nothing will stop those nagging doubts -still gnawing at me 2000 miles later.I've convinced myself I left the idler pulley bolt loose.
Iirc, the tensioner would not behave correctly if the Allen screw was turned clockwise so you would have known straight away it was wrong.
At least you've had the practice beforehand to get it done a lot quicker this time around.

Been there got the T shirt and still confused ???

Bearing in mind I'm no novice with timing belts etc .... read on.

Service interval reached ( no whining ) so a new belt kit was fitted - whining started after the new belt ( Gates )

Stripped out and checked, all my work good - still whining.

The alternator belt and all pulleys also replaced - still whining.

left it alone for a few months - still whining .... my mind was being nagged and nagged so I bought and fitted ANOTHER new timing belt kit - still whining !L

left it alone for another few months - still whining - in the meantime my alternator had failed so I fitted a new one - still whining so that wasn't it either !

Still whining all these months later  .... ?????

What else can it be ????

Anyway I'm confident my work was good so left all alone and its now been a couple of years - no plans to dive in deep again.

Go figure as the Yanks say.

Thanks again for all the help/info so far people.
 
I believe have now stopped the whining (from my cambelt at least…)!!!
 
As I suspected, I’m pretty confident it was down to the tensioner not being positioned correctly, which must have prevented the spring mechanism from doing its job, even though the tension was indicated as being 100% right.
 
Clearly it is completely my error. The only thing I can think of is that when I was adjusting the tensioner with the hex key originally to get the new belt on, I must have turned it in such a way (clockwise instead of anti-clockwise!?) that got it in the “wrong” position.
 
I have since taken the tensioner off all together, pre-loaded spring with the little pin that comes with it (thankfully I still had it), and put the cam adjuster in the “loose” position on the tensioner.
 
Popped it back on, pulled pin to give initial tension and rotated hex key ANTI clockwise to re-set the tension correct.
 
I decided to run the engine up to running temp (where this whining was at it worse) with the lower cam cover off (just in my garage – not out on the road) and this time no whining.
 
I could also see the tensioner adjuster marker had moved upwards, showing it was doing its job accommodating the thermal expansion.
 
All back together now with another new crank pulley bolt!
 
Hoping that’s that job done for at least another 5 years or so!!

Well done!

I'm quite a confident mechanic but I still take quite a few photos of things I'm taking apart because in my younger days I didn't think I'd need to and sometimes cocked things up.
