Overheating can be caused by a number of issues. You have addressed a couple of them by replacing the thermostat and the cooling fans. Are the fans coming on as they should ? The fans rely on other components like the coolant temperature sensor to trigger a signal to turn them on when the temperature gets to a certain point or the air conditioning is switched on. The cooling fan relay is another but if the fans are coming on, odds are the relay is good. Another possibility is a head gasket or gaskets failing. The engine would most likely overheat quickly and the cooling system level may drop. If head gaskets are ruled out, it’s possible there is a blockage in the cooling system restricting proper coolant flow. The radiator may be clogged. An infra-red thermometer should be used to detect temperatures across the radiator as well as across various points of the cooling system. A cooling system flush may solve the problem of the radiator is clogged.
