Hello from Austria!

My name is Christof (42) and I'm living in Austria (middle Europe). There are not a lot of Lexus on the roads, but I love them. Some years ago I had a LS400 (1990) and three years ago I had two GS450h. Last week I bought a 430...
Before starting to talk SORRY FOR MY BAD ENGLISH!
I hope everybody can understand!?

My questions:
-My 05' LS430 was imported from California to Austria in 2015.
One owner, 69.000 miles, but the timing belt is 18 years old...
it will be replaced next week.
I also bought a new radiator, because I heard, in some cases the coolant mixes with the ATF-fluid. I bought it new from a guy who ordered the wrong one. On my car it fits.
BUT: Could it be, that it is made in China? There is "CHINA" written on the Top beside the Toyota part number!? (see picture)

-Should we do this radiator-job after 69000 miles? From outside, the old one looks fine...

-After changing the radiator, should we fill up the ATF? Or isn't there much lost?

-Mark Levinson Problem:
I read a lot of amplifier failures.
BUT: My radio does not give any noise... the switches are also dark when lights on and no switch is working? Fuses are ok.
When I tell the Voice-Control "AUDIO ON", the Radio is working!??? But a can not turn on/off with the button, no searching with the buttons possible, can not change volume.
On the screen I can change treble, bass, etc.
Could that be the amp, when the radio is working and only the head unit does not work?

OK... thank you very much for reading and for some answers.
Have a nice day, best regards

Christof

 

That's the radiator

 

That's my LS430

 

Try to figure out if Denso manufactures radiator for Toyota in China. Radiator is not complex to make.

I think you meant radio makes no sound. I would check electrical output first but it is likely to be the amplifier.

 

The part number on the radiator doesn't check out.
1640050231 is the correct part number.

 

Thank you for your answer!
I got it in an original Toyota-box with the number you told me on a sticker.
So i am afraid, that i got a cheap product in an "expensive box"!?

Best regards, Christof
