overheating on 1995 Lexus ES300

where is the thermostat on this engine.
Will a bad radiator cap cause overheating?

Its usually where the upper radiator hose meets the engine (thermostat housing) and the thermostat housing usually has 2 or 3 mounting bolts, Stop by a Napa auto parts and have the counter person point it out to you

Yes, Each vehicle has a certain PSI radiator cap and once it looses its pressure holding capability it could overheat as coolant and water has a higher boiling point when its under pressure. Have a shop pressure test your cooling system
