Timing belt change - parts?

AJ · 01-11-07, 10:44

You've already figured it but just to clarify..
On non AC cars the power steering pump mounts between the mounts of the aircon and the mounts for the power steering (with aircon). So there are 3 belts for that combination:
with aircon:
-belt from crank to air con pump
-belt from aircon to power steering

without aircon:
-belt from crank to power steering (which is a different length to the crank -> air con above)

I went through all this headache trying to figure what I needed when I junked the aircon pump. The mountings for the aircon & power steering are quite cleverly designed.

When I changed my belts I got bearings from Tanc Barrett (Which he recommended) to fit in the tensioner and the idler IIRC. You'll have fun with the bolt holding on the rear section of the belt cover.....

It goes through a water jacket so when you take it out, you'll get soaked :-)

I think the only other thing that gave me trouble was that bl**dy PAS & AC arrangement.

So....can I just replace the cambelt tensioner bearing and not the whole thing???

I got it as one piece item from Walkers.

Can you remember how much? Never thought of going to them, was just going to the dealer

I dont unfortunately, didnt ask. I believe they are just main dealer prices though.

**jimnielsen** · 27-10-08, 09:25

Now that I have had a fair bit of track time with the Q4 - I'd like to replace its timing / balance and accessory belts if I can. I have read this thread - and I am still confused as to what exactly i need. I'd like to remove the air conditioner compressor at the same time as well - so I'd like to use a belt set that will allow this..

Is there a single part number from a single supplier that I can use for all of this?

Thanks - jimn~

**AlfaJack** · 27-10-08, 09:56

Would you order them by an Alfa dealer or would you want to order them via the UK?

http://www.alternativeautos.co.uk/ are very helpful...I dont think there is one single part number for a kit though.

**jimnielsen** · 27-10-08, 10:16

I'd don't think that I can get any of the required parts here, I'll email the guys at alternative autos - and see if they will ship to oz

... thanks for the lead.

I contacted Steve from Alternative autos - a complete kit is 125.95 (pounds) including the belts and tensioner parts. Does that sound about right? They will even ship it direct to me...

cheers, jimn~

**wrinx** · 27-10-08, 10:46

Sounds reasonable to me, the parts from a dealer would be much more.

I would check exactly what the kit consists of...don't want to be short of an idler or bearing!

Yes, that is about right, probably plus 17.5% and shipping..

**jimnielsen** · 27-10-08, 19:17

thanks - I will get them ordered. Is the operation needed to fit them all - more OR less difficult than changing the clutch? Space looks, well um.. tight!

**wrinx** · 27-10-08, 20:18

Dead easy job imho...but then I've not changed the clutch yet

A flywheel locking tool makes life MUCH easier and you'll need another "special" tool to remove the Balancer shaft bolt.

Then it's just like doing the belts on any car really. Thought I posted my experiences recently....
If you change the water pump you'll need to drop the engine, I managed by just taking out the upper and lower engine mounts (belt side) and letting it down the inch or so that it drops.

Edit: I'm wrong, my only post was this:

Not a bad job to be honest...just time consuming

I can confirm that dropping the engine 25mm (undo the top and bottom engine mounts) will give enough space...although I did have to get naughty and use a crowbar to get the WP pulley wheel out

So none of that nonsense that the manual tells you!

This might help too:

**jimnielsen** · 27-10-08, 20:55

thanks, Wrinx - I'd forgotten about the flywheel locking too - will have to make one - not so sure about the other special tool that is needed. It'll probably still be two weeks before I have all the stuff. I've never changed the timing belts on a car before - hence my apprehension. I am not planning on changing the water pump - if it fails I will use an electric one instead anyway. Any hints on the problems associated with changing to a 'non ac compressor' config?

thanks, jimn~

**wrinx** · 27-10-08, 21:17

Gery has also asked this question http://forum.berlinasportivo.org/showthread.php?t=1279 and I can confirm it was AJ who did this as his post is at the top of this very thread

Doing belts on cars is fairly straight forward....just make sure the timing marks line up correctly, tension the belt so it's tight when twisting approx. 90degrees by hand, along it's longest run.

These are the timing marks:

Rotate the engine BY HAND at least twice after fitting the belts, to check for valve to piston contact and other nasty noises.

Got to be less difficult than the clutch...few hours work really. I remember you wanted a guide which typically I didnt get round to but I did find one on the Fiat Coupe website:

http://www.fiatcoupe.net/howto.php?I...ter=9#content2

BTW, when the water pump breaks it doesn't just stop pumping water, it leaks everywhere too

**wrinx** · 28-10-08, 16:08

...although hopefully you'll get some warning like I did, fluid leaking and copious amounts of steam

**jimnielsen** · 03-11-08, 04:30

I received my timing belt kit today - I'd like to put it on before I use the car again. Should be interesting. You can see the part numbers of the various components in this pic.

cheers, jimn~

Does someone have a pic of what looks like to mark for the countershaft pulley (intake side)?
I?ve always aligned to the bolt of the water pump iirc.

@jimn, great to have the parts #, thanks!

That is correct - pointing down.
