Faulty/ noisy alternator- advice please


Recommended Posts

Hello, the - what I think is the alternator or the area near it has suddenly become very noisy (see video) sounds like a bearing noise. If it is the alternator can it be fixed or is it a replacement. The belt appears to be in good condition but is it best to replace that also? If replacement where is the best place to buy one and can anyone supply me with a part no. please. Series 1 hybrid  E4 - vin ATH10 0013973. many thanks

Picasso will supply you with part numbers, if he can.

 

What part numbers do you need ?

 

Belt, alternator, both, any other parts ?

Not sure what is needed, I assume if it is the alternator I would have to replace it but if anyone can advise me what is required and if anyone has had a similar issue.

Alternator part no. G128028011  on hybrid these are not normal alternators they are high voltage and cost over £1200 + vat from toyota they also not repairable i personaly dont think its the alternator i would be looking at the belt tensioner  which is part no. 1662028030   have atatched a drawing circled in red

Hi, thanks for the info- if it is the belt tensioner where is the best place to get one- I clicked the link but Partsouq showed "nothing found"- I searched on Toyota EPC and found the info attached- are there any other suppliers I could try?

Just had the garage check it and you were correct- it is the belt tensioner- need a new belt also so if you can advise the part no. it would be appreciated. Garage say I can still use the vehicle which is a relief. Thank you for the help.
