Seicento 1108 Alternator removal and refitting
Without removing the engine mount

Getting started

Before we start I am not going into too much detail here as many of the routines are simillar others posted.

1. Nip down to your local motorist discount shop and invest in an 8mm allen key or socket - the type with the ball end so that you can attack allen screws from angles other than 90 degrees or straight on. This is crucial to making the job easier as the bolts not only have a 16mm hex head but the 8mm socket too.

2. You can only get to the alternator by jacking up the car and removing the right front wheel and the plastic inner wheel arch covers (seems almost all the jobs I have to do involve doing this)

3. You will now see the alternator nested neatly in the top right hand corner of the gap, along with the two bolts: The bottom mounting bolt is easy to get at, it is the adjusting bolt at the top that is the pig.

Re: Seicento 1108 Alternator removal and refitting

A very inventive solution to the problem.
I had just done the alternator on a Cinq sporting before I read this, I loosened the engine mount as per the manual, and it can be a ballache!
I used a jack and a piece of wood to support the engine- that was no problem, the difficult bit is the top two bolts on the engine mount are impossible to access with a socket as they are too close to the body. Removal of the expansion tank (push it to one side still connected) makes this just about possible but the smaller bolt is still really awkward to get to without a 13mm cranked ring spanner.

So there you go two methods, you pays your money and takes your choice!

Absolutely brilliant guide. Cut about a cm off the bolt and still plenty of thread going in and even easier. Thanks. Dan

Is this the same on the Cinquecento?

Thanks

Re: Seicento 1108 Alternator removal and refitting

Can I just say, you DON'T need to remove the Engine mount.
Get a small block of wood & a trolley jack, place the block on the jack, and place the jack under the sump, then lift the engine up a few mm then you can get the the bottom adjuster bolt with a 16mm open ended spanner.

I did this a few weeks ago on my Sei Sporting, hence whay I said you don't need to remove the engine mount.

Big thanks to Ming (ycming) & Steve (Clock34) for the help getting my beast running again.

Post Re: Seicento 1108 Alternator removal and refitting

Have just taken the alternator off my daughter's 1.1 Seicento SX. The advice is spot on, the top bolt does foul the engine mounting a little as you remove it, but it comes out with a bit of downward coaxing and 17mm open ended spanner. Taking 5mm off the end should leave enough clearanceto get it back in comfortably and with enough threads engaging to nip up tight.

Thanks very much for the advice. Saved me taking the engine mounting off which would make an already unnecessarily complicated procedure just crazy. FIAT - engineering by Roald Dahl ! Most alternators I've changed on other cars have taken about 15 minutes.

Fantastic guide my alternator was seized solid after sitting for some time this guide helped extensively, I didn't cut the bold just inserted it from above the mount.

3. You will now see the alternator nested neatly in the top right hand corner of the gap, along with the two bolts: The bottom mounting bolt is easy to get at, it is the adjusting bolt at the top that is the pig.

[BREAK=Removing the alternator]

1. Disconnect the earth lead from the battery (for safety - don't want to be shorting any electrics here do we?). Discoonect the two wires from the back of the alternator (one is a simple terminal and the other is bolted on). This done you can attck the mounting bolts.

2. You will need to initially loosten the mounting bolts with a 16mm spanner as the allen key won't be beefy enough. However, when loostening the top adjusting bolt use an open ended spanner and not a ring spanner. The reason is it gets trapped by the drive belt and wont budge, which means you have to cut the belt like I did (I was replacing the belt anyway, but that's not the point)

3. Once loostened you will find it easier to continue to remove them with the allen key. Fully remove the bottom mounting bolt first and then the top adjusting bolt.

4. You will find that in the final stages this bolt will foul the engine mount, but by holding the alternator at an angle and with some patience you should be able to get the bolt out.

[BREAK=Putting it back]

This is where my FIAT mate got cocky: "Yeah it comes out ok but it won't go back herrrr herrrr herr". WRONG!!!! it will and here's how.

1. Take the bolt you intend to use as the top adjuster bolt at cut approx 0.5cm off the end (that's half a cm not 5) - there is plenty of thread on the bolt and cutting this off the end makes no difference.

2. Carefully file the end of the bolt and the lead in to the thread to make screwing back easier and to avoid it becoming cross treaded. If you don't there is a chance it may go in cross threaded and knacker it all up. It is an idea to try it in the screw thread without the alternator first to see how easy it goes back in. If it won't a bit more work is needed.

3. You will find the top bolt goes back in easy peasy, especially if you do the majority of the tightening up with the allen key. It is easier to use this whilst keeping tension on the drive belt, and will nip it up sufficently to stop it moving whilst you get the spanner on it.

[BREAK=Final Stages]

1. Conect all the electrics back up, replace the plastic wheel arch bits and stick the wheel back on

2. And remember always use axle stands when working under your car - never rely solely on the jack.

[BREAK=Why Bother?]

Yes I know that the engine mount is only three bolts, but you have to find a way of supporting the engine without the mount. Easy when you are a main dealer full of equipment, not so easy at home; and I dont fancy renting a hoist just for this either.

The only other way is a trolly jack under the sump (feasible - but not really recomended that one).

Plus once it is done, it is done for good and you never know when you might need to remove the alternator again.

Re: Seicento 1108 Alternator removal and refitting

I tried to do this at the weekend on my 2002 Seicento. two questions:
1. What is the best spanner to get at the top bolt? I couldn't get enough torque on a standard length 16mm open ended spanner, and (as you say) a socket set is no good. Do you use an extra-long 16mm or a stubby spanner, or something else? I didn't have the tools so gave in.
2. What is the allen key for? My alternator just has the two 16mm bolts.

PS, what I find irritating about this is that this whole job needs to be done to get the timing belt case off. My alternator is fine, I just need to access the timing case.
