LS400 Alternator needed please

[MerchantOfVenice]

Hey all where can I get a genuine denso alternator from for my 1997 ls400 please?

Many thanks

No joking…you could get your unit rebuilt.

it’s not too bad to remove. That said obvious route is Lexus Dealer like Lexus parts direct the OE one, not to be confused by parts dismantler by same name but a second hand unit from them is an option with obvious risks. Or Amayama is a good source.

In olden days refurbing was very common.

You might get a Denso unit not made for Lexus but wiring plug might not fit and need sorting and it won’t necessarily be made to Lexus specification. 🙂

Thanks for that.

Could anyone recommend a good rebuilder that they have used before?

Any idea on how to remove it?

Many thanks !

Have a search on this Forum and other Lexus forums plus YouTube.

Folk will pitch in…from memory release auxiliary belt. Identify alternator fixing bolts.

jack up and support vehicle. Undo from top and underneath as practicable. Draw unit forward and out. This will expose electrical connector for disconnection.

It’s a step taken in a cambelt change so it will feature in those guides too. Hope that helps.

Use your usual Lexus servicing guy to advise and assist maybe ? 
Where in London are you ?

I’m in bucks. Problem is I can’t drive the car as all the lights are lit on the dashboard when you start it and mot has ran out. So need to get this sorted then get mot.

i was reading the alternator is most likely at fault.

Disconnect the Battery first before removing the alternator.

You can try the company below, it's local to me and I had my alternator tested by them - not rebuilt/refurbished but having visited the company I would take my alternator there for a rebuild without hesitation.
You can send your alternator to them, they will sort it out and send it back, visit the website or give them a call.

I used westlancsautoelectrics.co.uk/
They were superb. They sent a carrier to pick the alternator up.
 A new one came back 4 days later with an 18 month warranty (longer than the Lexus main dealer), and at half the price of the main dealer quote.

Plenty on eBay such as this one if yours is the round plug

or this one if it's the oval plug

If you absolutely have to have a Denso then chances are you will need to order from a Lexus/Toyota dealer and pay their prices.

£150 sounds probably less expensive than having your existing alternator refurbished / rewound maybe 🤔

Double check it’s the correct one tho’ ……. just in case ! 
Good luck

iirc Ribblesdale Auto Electrics quoted £150 for a rebuild on my alternator.
New one from Amayama ............................. £932.80 + shipping and import duty/taxes so I guess around £1200 maybe.

I managed to sort it in the end.

Just needed an Italian tune up!
