So my alternator died i'd say about a month ago today. My car was towed to lexus around the same time to see why the car was dying. After a few hours I got a call back saying it was just my battery and they recharged it for me, great. Well about a week later I decided to replace the battery that way I knew the problem wouldn't surface again. Anyways, yesterday the wifey is driving the car and calls me and says the car is acting up again, so im upset at that point and call lexus, I drop the car off today about an hour later they say its possibly a bad batterey so I go back to the place where I purchased it and they say its a bad alternator, WTF! I go home P@@Sed off and start to test the car myself. As I tested the car with a multimeter I surmised it was the alternator. Brought it back to lexus same day and spoke with the tech myself and said they simply checked the battery and not the alternator. An hour later they told me it in fact was the alternator. Woohoo! Anyways $656.00 for alternator and $200.00 for labor.
Im deciding whether to do it myself, anybody know how?

2007 Lexus GS350 RWD 86000miles

 

Heres a reman alternator off ebay for $175 shipped.

http://www.ebay.com/itm/LEXUS-GS350-3-5L-2007-2009-ALTERNATOR-/260968784331?pt=Motors_Car_Truck_Parts_Accessories&hash=item3cc2f3a1cb&vxp=mtr
Ive done a water pump on my gs350, and that was easy. This shouldn't take much time to install yourself.

 

rockauto.com has them for $170.00 I would go with them instead of the ebay link i posted.

 

Yah, I seen those just not confident enough to remove the alternator considering it is well tucked in the drivers side engine compartment. But it actually looks straightforward as of what to do.
Just need some instruction.

 

Well, just ordered alternator off ebay. I hope it works.
Paid 199.99 for it instead of the 656.00 for oem.

 

My alternator died at 118k miles. did it at dealer. It's ok, I need the car.

 

It's only a .8/hour job.... But requires AC evac per manual. You may be able to move compressor aside without discharging and disconnecting lines, though....

Why thank you for your time and information, greatly appreciate it.

 

I literally changed out my alternator about four days ago. With the $650 Lexus charged, thats insane. But I needed to get the car going and nobody sells them. It was pretty straightforward and I was able to remove the alternator without removing any other part. I did have to remove that clip that holds the radiator hose, that was it. Took me a total of 45 minutes to remove and install the new one. FYI I am no mechanic.

 

After reading that procedure shown above, I went out and looked at my wifes car. I didn't see where anything needed to be removed or drained to do the job.

 

Like I said, only thing that had to be removed was the radiator hose from the clip, them remove the plastic clip that held the radiator hose. Nothing else. Really easy job.

 

Oh, and getting the alternator at just the right angle to get it out

 

Yea, the service procedure is a bit exaggerated.

 

anyone noe GS300 RWD alternator part no ,thanks

 

I have a backup alternator sitting in the garage I got from a local wrecker from an IS250 that had 9K on it... I paid a hundred bucks.
