:confused:

hi to all,,

i have a phase 2 3ltr gtv with 49k on clock.
it had cam belt and tensioner change at 45k miles last sept.

both idlers and water pump were not changed at that point.

is this normal practice?, if not does that mean the whole lot [cam belt, tensioner, water pump, and idlers] need to be done again??

any advice would be gratefully received.

many thanks :)

Unless the tensioners are worn or you ask for them to be done they won't be done.

You can change them afterwards without doing the cambelt. :thumbs:

My cambelt was done 25k ago, and the Aux tensioners were not done. Now one of them is squeaking on startup and at tickover.

They are quite expensive so brace yourself. An aux belt and the three tensioners costs around £150

They should be ok to fit yourself though by the looks of it.

cheers symonh for the info that the aux tensioners can be changed without the cam belt thats good to know!
but i am a bit confused, is the aux. tensioner the same thing as an idler pulley? also i have never heard of an aux belt is this the same as the cam belt??

excuse my ignorance im kinda new to mechanics but certainly looking forward to getting my teeth into sorting my pride and joy out!! i sold my motorbike and bought the gtv for the missus as it is the only car she has ever wanted and now im totally hooked into alfaworld!:D

one other thing i have noticed, when i take my foot off the throttle at low revs there is a faint whistling (closest thing i could describe it as) sound for a couple of secs, any idea what this could be?

cheers again :)

The cam belt is under the cover and drives only the camshafts.


As for the auxillary belt this is on the outside of the cambelt cover and drives the alternator, air con compressor, the power steering pump and the water pump. It can bee seen and changed from under the driver side (on RHD) wheelarch. After removing the wheel you need to remove a small access cover, then you can see the belt and tensioners.

The Fixed tensioners/pulleys are often referred to as idlers, where as the adjustable tensioner is the one that is sprung so tensions the belt.

There are 2 fixed tensioners and one moving tensioner on the V6.

If you need a copy of the V6 24V manual that shows the belt layout, PM me your email address.

Regards,
Simon.

@ Symon - By that do you mean the cambelt idlers can be done without having to remove the cambelt. That would be great.

I think the cambelt and tensioner on my car were replaced just over 2 years and about 10,000 miles ago, so they should be ok for a while yet, but I don't think the idlers were done. If they could be done separately it would save me a bomb!

The Auxillary belt and tensioners can be done without touching the cambelt.

The Cambelt idlers and tensioner have to be changed along with the cambelt.

Cheers.

Ok, I wouldn't feel happy diving the car "spiritedly" if the idlers haven't been changed. I've heard they can disintegrate. After all, the ones on my car have probably never been replaced in the 140,000miles the car has done. They've done their bit. I'd like to do some sprinting later this year and the car needs to be tip-top.

Looks like it a full cambelt, tensioner and idlers job then... At least it will be good for another 4 or 5 years.

The cambelt idlers on the V6 are made form metal so they shouldn't disintegrate as such, althought the bearings themselve could in theory seize up.

Cheers Symon. That reassuring. I'm wondering whether to leave things alone to be honest. The cambelt and tensioner were definitely replaced in Sept 07 and the car has done just over 10k since - which should mean it'll be good for another 18 months to 2 years.

The only place I've heard of the idlers breaking up is from a specialist.

Has anyone heard of the cambelt idlers breaking up? If they are indeed made of metal then the chances of them "breaking up" is minimal I would think.

I would say your car is ok for the time being.

Autolusso (and many other specialists) recommend 5 years or 60k

Even if you play it safe and do the job at 4 years or 48k you still have a year left.


Mine were last done 28k and 3 years ago.

Yes, if no-one has any horror stories of the idlers breaking up then I'm going to leave it be for a bit.

Right, more money for the respray :thumbs:

Seriously though, if anyone has heard of these breaking up or causing problems then please let us know.
