Answers :

Your lexus thermostat is not on top its on the bottom behind the hose.it is a pain to replace, and it is probably something else so check first.
Possible the thermostat is stuck closed and doesn't allow the coolant to circulate through the engine. Somewhat easy fix. Thermostat is usually located on the front top of the motor at the end of the top radiator hose. To change loosen the coupling bolts and remove the metal cover. The thermostat is round, made of metal, usually copper and is about the size of the radiator cap. It will come out pretty easily. When installing the new one be sure it's in the right way, it's a one way valve after all, so the flow is going the right way. There is usually arrows showing the flow direction on the radiator and or hoses. A gasket is required to help seal the thermostat in place. Be sure to use the proper torque setting to secure the bolts holding the coupling. They're not very expensive to replace. You may want to purchase a repair manual for the vehicle as well it's very helpful. Happy tinkering
