I appreciate you doing these videos. My 2006 has 122k miles on it. My radiator cracked at 80k miles in 2018 and it was replaced with the coolant but it is interesting to see the process.
One of the reasons my video was a little bit long, is that I showed how hard it is to access the engine block drains on both banks of the V-6. Basically, not possible due to the big engine in a tight space. One alternative is to heat the engine up until the thermostat opens, shut off the engine, and drain the radiator. That will drain the heater core and most of the engine block. I did that recently in another video of my two Corvettes having their coolant drained with a hot engine. The other alternative that I mention in this Lexus video is to simply drain and fill the radiator, then come back a few weeks later and do it again after the new coolant has mixed with old coolant during driving.
In all of my cars, I just buy the factory coolant from the local dealership parts counter. The price is about the same as buying an after market coolant from a local auto parts store. I don't like mixing coolant brands in my engines. The 2009 IS250 would be fine using the same coolant shown in my video.

Hi John, I was curious why you didn't drain the coolant from the engine block. Thanks.

It's a self bleed system, the tube off the reservoir does the job.
What is the best coolant to use for Lexus is250 2009?

Great video! Thanks a lot!
You are welcome. Thanks for watching.
Can you do differential fluid change next?
I hope to do that fluid soon and I will plan to make a video when I do.
Do you really need to lift the car?
