Hello Everyone,

I actually own a 2010 ISf and being the second owner, i did not know what they did or did not due other than trusting lexus. So I changed the differential fluid my own self and as well did the spark plugs, Lexus recommends to get them done at 60k. I can tell you on my F i have a bit over 50k and i am not very mechanically savvy and was able to do it all my self in a day in a half. I can tell you i got the fluid for the diff at lexus bought two quarts and as well got the plugs and decided to change the filter to K&N. The spark plugs took me about 3 hours to do and as well doing the diff fluid took about an 1 hour. I can tell you this much it will save you some cash as lexus charges for the plugs about 400.00 and the diff 275ish, And in reference to the transmission the fluids are non serviceable i have asked lexus in dallas/plano Tx and as well even looked at alldata and its non serviceable. I will try to put some pictures on my page on how to get it done. i went through youtube vid's on the IS250-350's and saw that the ISF is not much different I had two issues with pulling some coils out but other than that nothing major. I do plan on flushing out the coolant and as well doing the brake fluid change, looked at alldata just a matter of draining the fluid in the reservoir and adding new fluid.

Changing the ATF in the IS-F is completely different from the IS250 and 350. It's a lot easier and can be done with conventional equipment. I still wouldn't waste any time doing it, but if you're bent on it, best of luck. The 250/350 don't have ATF running anywhere outside the gearbox, so it's a lot harder to do a full fluid exchange.

Why are you planning to replace coolant that does not get replaced until 100k miles?

The brake fluid flush isn't just draining the reservoir and adding fresh fluid. You need to bleed all four calipers. Just changing the fluid in the reservoir doesn't get the bad stuff out. The bad stuff is in the calipers, so if you're going to bother with it, you must bleed the calipers. Otherwise it's a waste of time. The whole reason for the fluid change is to get out the moisture that has collected in the system to prevent it from causing corrosion over the long haul. Water dissolves into brake fluid (DOT 3, DOT 4, & DOT 5.1) to protect the brake system from corrosion. Silicone fluid (DOT 5) does not pull the water out and has been known to have water droplets collect in the calipers and cause corrosion (again, over a long term, it doesn't happen quickly.)

These cars are designed for minimal maintenance. The only real PITA job is the valve lash inspection, and they've done away with it on the newer models. While I don't disagree you have no idea how a used car was maintained, you're planning to service things the factory doesn't expect to have serviced until considerably more mileage.

We've also had quite a few members have issues with oiled air filters contaminating the MAF. Keep a close eye on that K&N and if you have driveability issues, clean the MAF first.

Do you all get your Fs serviced at a Lexus dealership or go to an independent mechanic? Time for my second service is approaching and wondering if I should go to Lexus like I did for the first complimentary one.

I know a trusted and honest mechanic who specializes in Toyota/Lexus and wondering if it's better to take my car to him because I hear all these horror stories with service departments being dishonest, etc.

All my car service is DIY unless it's body/paint work.

What is the recommended interval for COOLANT flush, I keep reading 100K, is that right?
