Hi All

Need a bit of help with my car, it has an annoying squeal when under load and the AC is on. I am trying to diagnose the issue and have narrowed it down to one of the following:

1. The bearings in the AC pulley are gone (unlikely as at speed it doesn't make a noise)
2. The belt is slipping (the belt looks ok, no cracks etc...)

So rather than take this to a mechanic I would like to try to fix this myself. I want to check the belts tension but not sure how to increase the tension on the belt, the below picture is a shot of the engine. Can somebody check and tell me how I would go about increasing the tension? If this is too hard a job I can take it to a garage. Car in question is a Seat Ibiza 1.2 2005.

Also note that using my hand none of these move side to side and when running none of them move side to side.

I would think its the pulley on the left of the alternator(?) (the small one)

Thanks all.

Just googled the tensioner and it looks like the pulley in between the 2 larger ones at the bottom of the photo, just to the left of where it says EPDM on the belt.

There'll be more info out on the googleweb.
 
There doesn't look like there's any manual tension adjustment there to me - are you sure isn't a spring loaded system?

Your belt also looks reasonably new, going solely by the fact the writing is still so visible
 
Hi guys

Thanks for the replies.

I think the tensioners are spring loaded, if that's the case I guess then the tension is fine or the spring isn't which would mean its lost a bit of tension?

i'll have a look one evening and see if I can find anything else.
 
Sometimes you find that kind of tensioner design simply seizes up over time, and so doesn't ever automatically adjust.

Next time you've got a free half hour, whip the belt off, get some wd40 and spend some time moving the tensioner to see if it frees up a bit - you can check for play/noises whilst you're at it.
 
wow look at all that space! :)

Squeaky belt, first thing I'd do is change it and lube the tensioner. your gonna have to undo it all so you may as well stick on a new belt for the sake of £15 it will be worth it and that belt doesn't look all that new.
 
Thank you all for your advice, I'm a keen DIY'er and not a mechanic but have serviced this car before so I am keen to learn (that and I'm a tight git :D)

Haha the perks of having a little 1.2 engine eh? Means everything is dead easy to get to. :p. Don't get me wrong I would love a bigger engine to be filling all that empty space :(

When you say lube the tensioner wouldn't this just make the belt slip even more? or do you mean lube where the bolt is?

Thanks again
