Having just spent a long time under and over the Croma 150 and replacing the auxilary drive belt I can see that the alternator replacement from the top side is certainly a tight proposition/job.

Would you care to share with us any hints/secrets that you have in replacing the alternator from above.... PLEASE

I removed mine from my 1.9 Croma last weekend after sudden failure at 41k miles. I will agree that it is a very fiddly and tight job to remove, many swear words later I got it out from the top & without taking the oil cooler off as stated on E-Learn, although I had to have the car raised. I was unable to get it reconditioned, the auto electrician said the parts were not readily available, he said it is physically the same as the Vauxhall unit but has a 150 amp output as opposed to the Vauxhall's 140. I had no success sourcing one anywhere until I contacted alernatormart.co.uk who have a link at the foot of these pages, they have supplied a brand new unit for 166.00 includingVAT & next day delivery with the pulley attached and no exchange with the old unit required. I hope this is some help to other Croma owners.

Re: Alternator replacement

Hi Nick,

No real tricks involved, It is just a job I wouldn't like to do too often, it seems you have to take half the car apart to gain access. My new alternator arrived from alternatormart.co.uk today and is as described in their advertisement, brand new with the pulley fitted. I will fit it tomorrow and hope this is the last problem I will have with this car.

What manufacture is this unit? ... any cross-ref numbers? 73501591? 102211-8270? My understanding is the 1.9/16v 150hp requires a 140A unit (?)

I didn't check the numbers on the unit I took off, I donated it to the auto electrician but I know it was a Denso, and he said it had a 150amp capacity. I fitted the new unit this morning which was delivered yesterday and all is sweetness and light again. I did not check the new part for numbers etc, but it is running o.k. Hopefully I will have no more trouble. Alternatormart.co.uk are quite helpful, the contact there is Martin who gave me my information if you need to speak to him.

Yep, me too, I was under the impression that the JTD150s were 140A alternators and the 2.4 had a 150A unit, so I'm confused

Re: Alternator replacement

Thanks for the alternatormart tip, Bobbyblue.

The original for a 1.9D 16v is a Denso MS1022118270 140A (taken from the original label on mine).

The replacement from them is a 140A one, made by Hella, which is related to Bosch apparently. Made in Europe (Denmark I think he said). 156.53 including VAT and delivery if you ring up with this part number. The price allegedly includes 10 discount for having the part number.

Don't bother with their website enquiry - they didn't reply to mine at least.

Re: Alternator replacement

Hi

Have just had the alternator go on my 1.9 16V Croma... same symptoms as others, light came on then everything failed except engine managed to limp home... bot forgot how hard it is to steer without power assistance!

OH is now looking at getting it out, have tried to download Elearn but no joy, can anyone email a copy to me or gives us some tips? Can it defo be taken out the top, what do we need to shift to get it out?

Cheers
J

Re: Alternator replacement

I'm told (via several posts here) that it can be taken out from the top.

Having said that I don't recall any specific details other than to connect the leads to the new alternator before replacing it.

Hi thanks for response, have read posts about taking from top but OH needs some convicing. He is experienced at taking cars apart but this one is offering a few challenges so any hints or at least a starting point would be appreciated, from anyone who has done it.

Re: Alternator replacement

Our Croma has just given birth to an alternator, there was lots of huffing, puffing and swearing and I quote 'the wiring harness will never look the same' but it is out.
Have a quote of 150+ Vat for a new one (have to give back the old one) or the possibility of 90 for one from an auto electricians (refurbished) Car will be off the road for a few days though.

Re: Alternator replacement

Ok, here's some tips from how OH did it.

Firstly remember to disconnect the battery before mucking about.

Remove wiper arms and plastic trim under windscreen. This allows you to remove the fuel filter and bracket, this is done by removing 3 10mm nuts below the washer jets (there are 2 pipes and electrical connections that need disconnecting here too). Once the fuel filter and bracket is out of the way, the job now looks possible! Slacken as much of the wiring harness as possible by disconecting sensors and removing cable ties this should allow the harness to be moved.

Take the right hand front wheel and cover behind off, this gives access to the belt tensioner and bottom mounting bolt (torx) back at the top of the engine remove the two torx bolts on the link between cylinder head and alternator. The two alternator electrical connectors are under a pivotting cover on the back of the alternator, you will need 13 and 10mm socket to disconnect them. To provide clearance when dragging the alternator out, the brake pipes can be pushed towards the bulkhead.

Good luck!
Thanks Roberto Blanco, dave thanked for this post
