Question about 2003 Toyota Matrix
When I turn the air switch the air comes out cold.
Even after the engine has been running for a while the air is cold.
I checked the coolant fluid and it is full.
How to replace the thermostat?
First drain the radiator of some coolant to the point where it won't spill over because you will be removing the radiator hose near the radiator cap. remove the hose. the thermostat housing is located at the end of the hose. remove the housing. then remove the thermostat. when removing the housing notice how the thermostat is installed. And be sure to have a new gasket with the thermostat. Remove all residue from the housing and the engine and put some grease to hold the new gasket in place. The replace the thermostat making sure it fits flush with the housing so you won't break the housing when reinstalling the bolts. Replace the hose and refill with coolant. Start the engine to make sure no leaks are present.
