How do you change the thermostat in a 94 mazada mx6?

To change the thermostat in a 1994 Mazda MX-6, first, make sure the engine is cool and disconnect the negative battery terminal. Drain the coolant from the radiator and remove the upper radiator hose attached to the thermostat housing. Unbolt the thermostat housing to access the thermostat, replace it with a new one (making sure to align it correctly), and then reassemble everything by reversing the steps, ensuring all connections are secure before refilling the coolant. Finally, reconnect the battery and start the engine to check for leaks and proper operation.
