How do you bleed cooling system on a 2000 Toyota Echo?
There is also another drain valve that is difficult to reach, on the back of the engine (you can get to it from under the car or reaching behind the engine) that also supposedly drains coolant, although I don’t really know what its purpose is because I think you can completely drain the system from the other drain valve (only a few drips came out when I opened mine). Some more info can be found about the second drain valve if you look into the instructions for changing out the water pump (which is NOT an easy job).
