Can you show me picture on how to change a thermostat on a 1997 Toyota Avalon?

I can't provide images, but I can guide you through the process. To change the thermostat on a 1997 Toyota Avalon, first, ensure the engine is cool, then drain the coolant from the radiator. Remove the thermostat housing by loosening the bolts, take out the old thermostat, and replace it with the new one, ensuring the gasket is properly seated. Finally, reassemble everything, refill the coolant, and check for leaks.
