Hello,

I would like to seek a DIY or even a quick verbal explanation on changing power steering fluid and coolant on a 2008 Lexus isf. I have purchased Toyota long life coolant about a gallon, is this enough to do a simple drain and refill for the ISF? And if anyone can provide me links for diagrams or websites that would help with my isf,, thanks

He is right about the power steering.

If anything, if you can't do a flush, find a competent shop to do it. I used to charge $50-60 to do coolant flushes. I haven't had to change out the coolant but I will check my car out and see if I can explain it in a simple process so you can do it if you really want to do it that way. I recommend a flush cause your car is pushing 3 years now, so that probably puts you at about 25-35k miles... would be worth the money. Doing this at these intervals will help things keep from getting too acidic in there and help things last longer. I will be back with something for you later.

Uses TOYOTA Super Long Life Coolant (SLLC)

The severe service interval on the initial replacement is at 100,000 miles or 120 months. Then replace every 50,000 miles or 60 months thereafter.

If your doing this as piece of mind because you do not know the history, then I would highly recommend using professional equipment to make your life easier on a very expensive engine. All you need is an air lock to complicate life.

No need to worry about PH balance on new coolants - they utilize hybrid organic acid technology (or HOAT) to prevent damage like this for extended periods.

With ethylene glycol or green coolants of yesteryear, this was a worry.
