Thermostat 05 Es 330

i always r/r thermostats in my cars every five yrs or so. Looking at the Lexus, I see it is under the fill cap and in a large holding bracket held down by 2 torx head bolts and one ?12mm. have to disconnect temp sensor and part of motor mount and take cover off top of motor to get the stat/bracket out. has anyone done this or know of link to a DIY reference?

Why bother, the toyota/lexus thermostats are really robust. My RX300 1999 still had same themostat 12 years later....unless you have problem, leave it alone.
