pauloil Posted January 26, 2012 Share Posted January 26, 2012 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?

lenore Posted January 26, 2012 Share Posted January 26, 2012 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. Quote Link to comment Share on other sites More sharing options...
