New Cambelt Problem

[Fred@BTM]

torque settings in autodata are still incorrect IIRC

i "can" do the job in 2.5 hours (bumper off method) but when people are paying over £600 i like to take my time

It starts leaking.

Mine never leaked it made a racket instead (dephaser type noise)

I'll have a look tommorrow, Im buying one of the trade-ins at work.The customer has part ex'd a nice 182 with both the cups for a Insignia 160cdti with a kit on and I cant find any evidence to suggest the belt has been done or not.

If you dont mind what would you recommend changing. My works copy of autodata says the dephaser if it moves and the crankshaft spocket if its the keyless type,bolts regardless of the type too. also people say water pump,aux belt and tensioners. This will cost a fortune with all the tools and if you've got it stripped you may as well change the dephaser while your at it.

I had a clio valver many moons ago and the belt was a doddle on that,room was a bit on the tight side but a really simple job,

[Fred@BTM]

waterpumps are quite rare, i've done maybe 30 ever

dephaser is a must plus the seal kit that goes behind both pullies - £25 for that, so is the aux kit (FULL KIT)

crank pulley info is wrong, reuse the non keyway pulley, no need to replace plus it cam be a tw*t to time up if its keyed

we did a vaxhaull master tech's car 2 weeks ago funnily enough, his exact words were "f**k doing that job!"

the process of fitting the belt isn't mentioned in autodata, you have to fit it in a weird order to get the plastic lower cover in/out without breaking it, then the belt need to be tensioned, the whole lot rotated backwards, recheck tension, lock it all up, tourqe it, turn the engine over reinsert tools yada yada yada

Im not a master tech, but I wont be put off just because its french Im suprised a mechanic would admit defeat like that lol. I like a challenge. Ive done timing chains and belt replacments on all the vauxhall units, The only thing that would put me off is if the price of all the tools actually outweights the cost of labour at a specialist.Even then I'd think i would have missed out on some fun if I went down that route. What addition of Autodata do you have? is it a cd based one on or is it the timing belt book?

[Fred@BTM]

we've got the latest CD, plus full renault manuals (which funnily enough are wrong too in places, translated from french)

I have heard back from the garage and they said that the timing is spot on and that a hose had come loose and this was what was causing the revs to fluctuate and the car to almost stall. Does this sound likely or should I be worried?

Thanks

Yes this would happen if a sensing pipe was pulled off, such as the one going to the MAF sensor.

i have picked it up from the garage. It is definately much better now than it was before. However now when i stop the revs are about 1000 then slowly dropped to about 8000 then do not move.

Is there a way of telling if the timing is still out?

Thanks for all the help with this.

I think you mean 800RPM and not 8000RPM! Its normal for it to drop to 1000ish, then settle to 800, especially when the engine is cold. If the timing was out, you would know straight away because it would be down on power - put your foot down and see if it feels like its got enough power. As a rough guide, you should be able to do a 0-60mph sprint in under 7 seconds when the car is hot (allowing you to rev it a bit higher). If you cant do 0-60mph in under 10 seconds, then i would say your timing is definitely off. However from what you have described, I dont think it is.

[The Fatty]

i would have had the water pump changed while they had it all off. i spent a fortune when i had mine done and had everything changed including all vvt gubbins. a bit over the top but piece of mind and i dont have to have it done again.

And with all that being done, you still dont have peace of mind with the way these engines like to drop a valve!

[jack_davey]

renault manuals (which funnily enough are wrong too in places, translated from french)

On that subject I don't think it actually gives you a torque setting for the lower idler in the timing belt section!
It says the upper one is 45Nm, then you look in the engine builders manual, and it says 50Nm!

[phate23]

I havent had a chance to look at our timing belt book yet, but if there is a conflict of info regards to tourque settings, I think its a case of might is right lol.

Is yours a genuine autodata CD?. I work at a Franchised dealer and they charged the company about £400 a year for that, and when the licence expired £400 the next year. it wasnt even pay your £400 and then your subsequent updates were extra,finally they stopped buying it and just got a T-belt book for "Foriegners" as we call them in the workshop.

I work for Vauxhall the system we use TIS2WEB is quite good the old tis2000 was loads better thou,whats the renault one called?

[phate23]

ive got the book now the guide rollers are stated @ 50nm tensioner @28nm camshaft locking tool nuts @ 80nm exhaust sprocket new nuts @80nm +86d and inlet sprocket @100nm blanking plug 25nm and crankshaft 40nm + 110d. does look tricky.

[Dan@519Automotive]

renault manual is full of mistakes and contradictions too. I use 20nm then 115deg +/-15deg for the crank pulley.

It also says to refit the lower cover before fitting the crank pulley, which isn't necessary at all
