Alternator replacement

Has anyone replaced an alternator on a 150 multijet. I am desperate to find out if you need to remove partially or completely the offside transmission driveshaft for access.

Re: Alternator replacement

Does this not answer the question:

https://www.fiatforum.com/croma/1978...ml#post2313839

I know it is a little cryptic but he is I believe a Fiat technician and it sounds like he removes and replaces them via top access.

Of course that does mean that whoever replaced your alternator did it via top access.

To remove the N/S drive shaft requires the car to be lifted, wheel removed, hub nut taken off and the steering/hub lower swivel joint undone. Suggest you poke your head underneath the car and inside the front N/S wheel arch with the steering on full left hand lock an see if you can see any evidence of nuts or bolts having been removed.

The way the suspension and hub parts get cakes up in fine dust/dirt then the use of spanners and sockets will disturb the dirt.

Re: Alternator replacement

Thanks for the reply s130 but 'no' it doesn't answer my quetion. The alternator cannot be removed from the top unless the engine is out and that will probably take more then the 4 hrs labour quoted for the job. There appears to be not enough clearance if you need to remove it from below and I was really asking for probably an experienced 'FIAT' mechanic if in the official procedure for replacement, the shaft is removed. Thanks once again for your answer as you were the only one to respond.

Re: Alternator replacement

if I may elaborate.....1.9's you get from top. 2.2's are bit trickier but no need to remove driveshaft. Just weigh things up & look for shortcuts, manuals are not always the quickest/best way to do things.

Then again I can extract a 20 note from the wifes purse while its in her grasp with a straw

Re: Alternator replacement

Mine went too last weekend. Completely seized so total and immediate loss of power couldn't even switch the hazzards on -quite scary. Part had to come from Italy but arrived in 4 days so not bad. MJ150 had to come out through the bottom with removal of drive shaft etc. All told with new belt and front pads 430.

Are you saying that the alternator seized and the drive belt was just running over the alternator pulley shredding itself?

Can't understand why such a sudden seizure would cause total loss of electrics, unless you had been driving round, shredding the belt (no noise????) and the battery went flat over several miles.

Also what year is your car? (Same question to others who have had alternator failures)

Re: Alternator replacement

Internal short in the alternator (aka catastrophic failure) would cause a massive power drain - I'm guessing. No plans to try my theory out though

Could be that there is some missing information here. Seizure implies mechanical failure. A diode/regulator/winding failure could result in exessive drain currents, even to the extent of possibly stalling the alternator, but I find this somewhat difficult to believe unless the drive belt was so slack as to allow the alternator to stall due to short circuit conditions. If this were the case then I would expect noise, burning/rubbing smells and ultimately belt failure.

Re: Alternator replacement

Agreed, hence the stated need for belt replacement. I'm guessing at bearing failure followed by seizure. The only way I can rationalize complete power failure would be if, during the seconds before seizure, the rotor contacted the main alternator body - hence the term 'catastrophic failure'. I would think that connecting the alternator output directly to earth would cause a few problems.

As you say, perhaps more information is required - if nothing else, to give other owners an idea of what might be about to happen / has just happened.

HTH.

Re: Alternator replacement

Sorry I haven't responded but not been on for a while. When whatever happened happened there was a catastrophic failure and a total loss of power draining even the battery. As soon as the AA tried to charge the battery there was smoke from the alternator as if about to catch fire. The next time I saw the alternator the fly wheel wouldn't turn and the belt had no flex and had a fixed shape as when in position probably caused by the heat. Can't tell you anymore other than it's fine now.

Re: Alternator replacement

Seems alternator failure is becoming a common problem as mine has just been replaced too (see Electricty - why can't the Italians get it to work?), so why are they so damned difficult to get - mine had to come from Turin which kept the car off the road for a week? Although it didn't seize like yours, so I was able to drive it home.

Not only that, the component is not unique to the Croma being used across the Zafira, Vectra and Signum range of cars using the 1.9 16v engine (and Alfa 159). In addition there are other manufacturers such as Lucas who offer alternatives.

Mine was done under warranty, but would have cost me 170 plus labour and Vat had I paid.

46.7K mls & alternator expired last night!

Noted various comments - but seems a little short on P/No.s etc.

What replacements have folks fitted? ... P.Nos? ... Opel? Vauxhall? Saab? Alfa?

(What is OE make?)
