It seems that you have dodged a bullet, there!  :y

Not really... The 40k interval was introduced to prevent idler/tensioner pulley failure caused by dealers literally only changing the belt at 80k...

No, it was the high number of idlers not lasting 80k/8yrs.  If it was caused by dealers making mistakes, it would not be a reason to change it ;)


*High number = probably lowish percentage, but deemed an unacceptably high number of failures.

Wonder how well the idler from the ContiTech Timing Belt Kit lasts on average.

That's the one put on mine.

No way of knowing unless you keep driving until it comes apart.  ;)
Shouldnt be any problems doing 40k / 4 years, but beyond that, who knows. I suspect it would go well beyond that, as Ive seen cars that havent had the job done for many miles and many years.
Its a gamble though.

Donk go over 40k by 1 mile, or the engine will explode, go over 4 years and car will catch fire. ;D,

10k over isn't a problem.

I've used their kits in the past, no issues.

I change my cambelt in the summer, as my old bones struggle rolling around in the rain, which means it can easily be 5-10k over.  I'd probably not want to leave it another 20k/year beyond that, for the sake of 70-80 and 90mins work.

I'll wait until the warmer weather then change it and do an oil change at the same time. Off to North Yorkshire near the end of summer so better to be safe than sorry.  :y

Thanks all for your advice.  :y

That's a very good price for a V6 timing belt kit. There used to be a kit on e-bay that only included belt, tensioner and one pulley (car needs two) at 19.99. Members bought 2 kits for a complete set up, and got a complete kit for 39.98, still a bargain. Most kits cost well over 100.

Can't recall how much mine cost[40-50 seems to ring a bell]bought off e-bay belt was contitech bearings were SKF and the kit included a German made water pump which had a metal impeller.It had everything in the kit that was needed and all DLK[he fitted it for me]did was change tensioner/roller onto the back plate already on my car and changed the water pump as his preferred method of doing the job.

On my 2003 Thames Valley Police Omega I note in the records that TVP changed the cam belt at 80k and 160K. In the same period they changed the clutch 4 times.

I purchased a  QH QBK337 kit which should contain all the tensioners,backplate and a belt from research,
(due delivery monday) I don't know what bearings quinton hazell use in their kits or what belt  :-\
if the belt is poor, i'll just fit a gates belt ,I've been using gates belts for years without issue on many cars
as i say, the kit fitted currently only has 7k miles on and is skf but feb 2012  :o
that's over 6 years and the car has NOT caught fire  ;D

I have never had a cambelt failure, but have suffered 2 auxiliary belt failures, both due to tensioner pulley bearings stiffening up. Not catastrophic failures, but very inconvenient. Following advice from Nick W, I now take the pulleys off occasionally and grease the bearings.

I suffered one as well, on my old 2.5. Luckily it was local. Wish I kept that car. :(
