Cam Belt Kits and Tools 1.8 CF2

Hi Folks,

I've had my 156 for nearly 2 years, itís a 1.8 t-spark CF2. The cam belt was done just before I bought at 74k, it's pushing 104k now. I've done pretty much all the maintenance so far and I want to have a go at the cam belt myself. I could leave it go for another few months but I've got a window of opportunity with the use of another over the next few weeks so I can afford to take my time and not be stuck without a motor. I've ordered a set of cam locking blocks, a tensioner tool and variator tool so they're covered but have a few questions about the kit:
1. From my research, the kit I need for a 1.8 CF2 is the same as all 2.0 16v engines but different to the 1.8 CF3; is this correct? Just want to be sure when there's two different kits for 1.8's.
2. From peoples experience, should I stick with an Alfa kit or can they recommend either an alternative manufacturer or an alternative supplier of an original alfa kit?
3. The variator was changed with the last belt, it's not noisey, should I change it anyway? If so, I believe there is a newer design that's more robust, has anyone got a part number, I might just check the part number and if it's not the newer design I'll get a new one?
4. Based purely on a cursory glance in the engine bay, there seems to be plenty of room for access, for anybody who's done one before, are there any bits that are tricky to access, bearing in mind the work will be done without the benefit of a lift (have axel stands and all that)?

Cheers,

Bryan

Re: Cam Belt Kits and Tools 1.8 CF2

The only tricky part I found first time I did one was putting the cambelt cover screws back in! They're different lengths so have a template of the cover with holes in it which match and as you remove a screw put it into the hole. You might need another set of hands/eyes.I used dial gauge and holder, some say its not absolutely necessary but I found it helped. Doing variator is not difficult as long as you have a good bench vice with jaw protectors and the tool that fits the variator (which you've ordered). You'll need heavy duty Locktite too.

Re: Cam Belt Kits and Tools 1.8 CF2

The hargest part I found on my 156 (Which is a 2 litre so may be different) was removing the auxillary belt fixed tensioner. The bolt inside is recessed so you cannot use a regular spanner on it, and there is not enough space between the bolt and the cross member to use a socket.
The solution is a swan neck spanner (15mm) my solution was to cut off most of the square drive end of a socket and weld half a spanner to it.

There is probably more space on a 1.8 though, but I cannot say for sure as I have never changed a belt on one.

Re: Cam Belt Kits and Tools 1.8 CF2

1. yes that is correct.

2. i dont trust oem gear, especially considering the number of premature belt breakages on this particular model. there are plenty of beter brands out there, i prefer gates but i'm sure dayco/contitech/bando and similar will be fine.

3. if it was changed 30k ago i would not change it again, wait for the next belt change, then the variator will have done 65-70k, which is a perfectly safe bet.

4. remove the driver's side wheel arch liner and access is shockingly good for a fiat.


here's a link to a well priced kit including the idler and tenisoner (but it should still be slightly cheaper at your local motor factor)

I'll have a swan neck spanner at the ready. I think the 1.8 and 2.0 blocks are much the same externally just with a different bore/stroke.

Thanks to everyone else for their help too, it's been most useful. I'll keep you op to date on my exploits.
