Having finally purchased a 916 GTV V6 Lusso after years of hanging my my nose over them, thought I had better start addressing a few maintenance issues by starting with the cambelt. The car is a UK 2000 (W) registered model with one previous owner and 66,000 miles on the clock. I was informed when I bought it that the cambelt had never been changed! I have fitted new belts on Vauxhall and Peugeot V6s before so thought I knew more or less what I was letting myself in for. Perhaps not. There is way less room to work in the Alfa and the documentation is somewhat lacking though the official workshop manuals and various articles here have helped a lot. I have everything locked up at TDC and the old cambelt, idlers, tensioner and two of the four cam pulleys off. Despite the age, the belt and bearing all look and feel perfect though the tensioner is showing some signs of wear on the pulley surface and slight movement in the bearing. Whilst I am (slowly) taking things apart I am also thinking about putting it all back together and unless I am mistaken I am likely to have problems fitting the cam pulleys, tensioner and idlers as there is so little room to fit a torque wrench and socket. On top of this, and despite looking extensively, I can't find a torque figure for the idlers. So can anyone tell me how you have refitted the above, have you found a suitable stubby hex/allen socket that fits? Have you manged to get a torque wrench into the gap and if so what wrench have you used and what torque figure did you use for the idlers please? Think I will be coming back quite a bit over the coming months for advice so hope I can tap into all your extensive and detailed knowledge.

hello v6coop, great choice on the gtv v6 got any pics :thumbs:

its highly recommended you replace all the pulleys and tensioners while doing the belt change along with the waterpump. well done for giving it a go, my v6 need a cambelt and although i have done a ts cambelt i think the v6 belt is beyond me i will be taking it to a specialist (£600).

this guide might help you theres a few good tips and pics

Thanks Jon. I already have an SKF cambelt kit so both idlers and the tensioner are included with the belt, hence my question about the correct torque for the idlers. Thanks for the link I had looked through this one but no info on my questions unless I have missed it. I was not sure about doing the water pump though. I understood the 3.0 V6 had a metal impeller and this was not prone to the problems that have plagued the plastic ones. I suppose you will all tell me it is sensible to do it whilst I have everything stripped down?

Change it for the sake of £80. Even metal impellers have shown signs of failing just takes a bit longer.

Thanks for the advice sounds like I will be doing the pump as well. Any thoughts on this one? Looks to be a good price and apparently the same brand as at Alfa Workshop (Bugatti????) for considerably less. Are there any torque figures for the idler bearings please? How have others refitted pulleys idlers, waterpump etc. with the engine in situ? Is it down to guesswork and threadlock using hex keys and ring spanners or is there a way of torquing them properly ?

Presumably you've 'locked' it using the correct cam lockers?

I'd leave the water pump until the next belt change, it's only done 66k.

I can't advise on reassembly as I leave cambelts etc to the experts.

Thanks for the replies.

JETRO - Isn't this torque figure for the camshaft pulleys not for the idler bearing?

CGTV - Thanks for the advice about the water pump this was my thinking too especially if I can't get a torque wrench into the gap. The cam locks were certainly advertised and provided as being the correct ones for the job and they fit perfectly so no reason to think otherwise.

My question was meant: 'how are you locking the cams' rather than were you using the correct ones.

I'm in the planning stages of doing the Cambelt on my V6 spider but I'm in the 'engine out' camp. If you were to do this again would you remove the engine or is it reasonably practical with the engine in?

I'm going to do a clutch (maybe GTA/solid flywheel conversion) and possibly a Quaife differential at the same time.

Don't scrimp, that's what kills these cars...

For the sake of saving £80? - With respect, that's pretty poor advice! :eek:

It's all to easy to just blow £80 - it doesn't go far.

I think he should replace the pump (while he's in there..) and think of it like an extra insurance policy!

Money well spent in my book...!

It's not just me that doesn't advise changing the 3.0 V6 24v water pump at every belt change. but hey what do I know?:rolleyes:
