How do you change a thermostat on a 2004 Toyota matrix?

Answer 1

To change the thermostat on a 2004 Toyota Matrix, first, ensure the engine is cool and disconnect the negative battery cable. Drain the coolant from the radiator, then remove the upper radiator hose and the thermostat housing. Replace the old thermostat with a new one, ensuring the gasket is in place, and reassemble the housing and hoses. Finally, refill the coolant, run the engine to check for leaks, and ensure proper operation.
