What kind of coolant to use on Toyota Echo 2003 automatic 4-door sedan

SOURCE: 2003 Toyota Echo heat not working. Fan, but no heat.

There is a valve on one of the heater hoses that allows heated water to flow through the heater core when you select heat. With heat selected and car warmed up check to see if both of the hoses feel warm. If not then water is not flowing through heater core and valve may need replaced or heater core is stopped up.

First thing to do is check the fluid level if that ok you may want to think about having the transmission filter and fluid changed, there are other possibilities but check these first

go to any kragen or autozone parts store, they will run the test for trouble code that turned light on for free, tell them u want an OBD 2 trouble code test, then post the code here.

SOURCE: How can I test the coolant temperature sensor on a 2003 Toyota Echo so that I can make sure whether or not it's working properly? Thanks for your kind reply.

Use a multimeter to check. unplug the sensor and replace it with multimeter. As the coolant warms you should see a voltage change. I don't know the exact figures you should see but it works on voltage change to close and open the circuit, hope it helps.
