I recently had an Overheating provlem on my 2006 Rx 400H. It turned out that i had toooooo much Coolant in the radiator. When that happens and temperature rises, the liquid that goes to the Expansion tank is simply not enough to cool down the liquid left in the radiator when it goes back. That's why never fill Coolant to the MAX mark. Always make it to be between the MIN and MAX. I know it sounds crazy but after changing the Water pump, Temperature Sensor, Both Radiators, Thermostat and everything you can think of (and still getting overheating), that was the only thing that fixed the problem. No more overheating. Since then i have driven well over 15k km(10000 miles)
