Title: CAMBELT CHANGE INTERVAL
Post by: Bose Addict on 08 May 2010, 10:52:53
Does anybody know why Vauxhall changed the cambelt life from 40k/4 yrs to 80k/8yrs for the 2003 model year?  Did they improve the belt or tensioner or were they simply having us on before then?   :-?

who told you it went from 40k to 80k?

Its other way around, it was dropped from 80k to 40k/4 years, due to too many tensioner failures. The belts don't really snap, its just the tensioners fail, and let the belt slip.

For all V6 and I4 engines its 4 years / 40k  :y

Actually it went from 36K (service intervals used to be every 9K) to 40K (10K service intervals) then to 80K (20K service intervals) then as you say back to 40K after various tensioner failure issues, however the 20K / 1yr service intervals stayed on.

Of course anyone who runs a car on 20K oil really doesn't wish to keep the car for more than the warranty period!

A Vauxhall service manager gleefully told me years ago that it went back up to 80k after my own 2002 model.  Now I've recently seen it with my own eyes in the service handbook of a late 2003 V6.  It's real, but I wonder if they beefed anything up to risk that?   :'(

service book was printed and delivered with the car, THEN the srevice interval was changed, so even though the book says 80k, the new service schedule superceeds this info, the book is out if date.

No parts where changed, and your service manager was either talking before a service schedule change or out of his wrong end, the later probably.

So be of no doubt, the service schedule is 40k or 4 years,

The End.

Fair point, but my 2002 book states 40k alright and VX website (text below) suggests it went up.  Perhaps there was a service bulletin in 2003 bringing it down again as you say.  Odd. 
'Vauxhall recommends for multi-valve engines up to and including 2002 models, a cambelt change interval of 4 years or 40,000 miles, whichever comes first. For all other engines and diesels, then please refer to your service book or consult your local MasterFit retailer.'

Put it this way mate...if your tensioner failed at 78k you would certainly be beating yourself up that you didnt stick to the 40k as you sat there with your scrap engined car! :) 40k is a good safe interval to change it and not to be messed with...leave it longer at your risk and quite often at your peril...

Think the OPs got a 2003 model mate and his service book says 80K.

Agree should be 40K or 4 years ALL V6 models. 

OP - ignore at your peril  ;)

changed mine at 80k (dealer at 40k)

out of interest, does anyone know the difference or have pictures of an original tensioner set up compared with an aftermarket ie "gates" kit  :-?

The bearings in the Contitech kits I used were stamped skf.

Regardless of which kit you buy the tensioners and rolllers are always skf.
Re. change intervals the revised tensioners and rollers from mini facelift onwards are certainly an improvement on original design from 1993.However I have seen cars with as much as 93k and 8 years old (ex met police)on the original be perfectly ok to having one with 66k seize and break belt.
Its also probably considering the number of hours running v actual mileage.

I'd guess that driving style will also have an effect on likelihood of trouble.  I'm no bearing expert, but surely the faster a bearing is rotating, the faster it 'wears out', as it will get/run hotter.  Red line it all the time and you're surely more in danger of a premature failure than if you drive it like an oldie?

Dunno, just wondrin'.  :)

Absolutely agree.  The problem is that I cannot trust the 80k statement in the 2003 service book unless I am sure that there has not been a service update bulletin or somebody can confirm that they improved the design in the last Omegas of 2003.  I'm sure that driving style must have an impact too.  Pity!   :(

When was the cam belt kit last changed? What date and mileage?

That's the whole point! GM didn't trust the 80K interval after so many tensioner failures they lowered it back to 40K.

There wasn't any 'improvement to design' of the kit as such, just three different backplate designs and the replacement of a lower tensioner with an idler IIRC. Point is, whatever the Omega petrol engine, change the whole cambelt kit every 40K.

The dealer notification was sent via TIS, point is that if anyone who works for a VX dealership (including the service manager) does not know the intervals I wouldn't trust them to polish a pair of shoes.

dont know how else to put it, 80k means nothing to any petrol omega, ignore it. But if you want to bang your head against a brick wall full of bent valves, carry on.
