Guys,

Just been towed home tonight after my daily smoker breaking down

Anyway, it turns out the cambelts broken (well not actually broken but has slipped, the teeth have been worn away). Now I had EXACTLY the same thing happen in August and fitted a new belt.

Looking back through old paperwork the car has had two belts in 4k miles

What can be causing this ? first belt I can't comment of standard of installation but second was donr by a very trusted mechanic............ can't see what would cause two to fail so quickly ?

Only thing I thought of was maybe an incorrect cam/ crank pulley has been installed ?

At least there's no engine damage as they are a non interference design

Cracking engines these.
Only seen this happen once, on a 1.2 Nova, took about ten teeth off, didn't do it again.
All I can think of is not enough tension, and it slipped taking teeth with it.
Are you saying all teeth are worn down, or just a section where it's slipped?

Cossiep

Not sure about how many teeth are gone as haven't got it off yet.............. however the last time it happended the belt was in a mess all the way round

This most recent belt was fitted using the proper tensioning tool as well

i was gonna suggest it being a wrong size tensioner or a bad batch of belts, did you get them from the same place mate??

Cossiep

mk2rstaff............... was a branded Contitech belt, these 8valvers dont have tensioners just uses the water pump

mk2rstaff

is the water belt pulley running straight and true then , not much else i can think of mate good luck though

Cossiep

not 100% sure but was a new pump in the summer..... will check tomorrow though, cheers

i had the same problem on a xe engine so might be relevant for this, the belt kept sounding like it was coming loose and on inspection i found alot of teeth missing, it happened twice so i dealt into it more the second time and found someone had fitted the wrong water pump (square toothed type) and the pulleys and belt where round tooth, may be worth a look.

Cossiep

Spot on m8, just what i've been thinking................. as it had a new water pump last year before i bought it therefore feel this can be the only cause

C4llyT

On one of mine Vaux gave me wrong belt despite giving them engine number, so may be onto something there

dave green

sure the water pump is not the problem. some have round teeth and some square, very easy mistake to fit the wrong pump


Dave

Cossiep

not the problem ?

i.e. pump selection isn't important ?

Water pump gets my vote too.

Cossiep

The Vauxhall guru has spoken

Will have a look at the pump tomorrow

sounds like a job well done and yet again i have learnt something new well done pf

even though i would never buy or work on a nova
