I have a2005 toy Prius when I add coolant to the inverter res, it fills up the engine radiator and there not supposed to be done texted what's wrong

SOURCE: coolant

check the rear heater lines on the right side(passenger side) of the van. there is a rubber hose that was leaking on mine. I found it after the dealer said nothing was wrong.
It did not cost anything for repair as they had a service note on it.

is the toyota running hot or do you just notice it blowing coolant out of that hose into the reservoir ????

if the engine is cool you can add it either way...hot or cold.but if its been running id let it run while u add coolant. but you can add it either way

SOURCE: coolant in coolant reservoir did not fill low level in radiator

you must drain air out of system
so when engine is warmed up, just unscrew slightly the thermo time switch which is the highest sensor and unit in cooling system besides the reservoir, until alittle air releases then when antifreeze starts coming out then retighten to specs. BE VERY CAREFUL !!!! LOOSEN VERY SLOWLY AND NOT COMPLETELY REMOVE FOR THIS CAN CAUSE BURNS. MIGHT WANT TO USE A RAG AROUND SENSOR. If this doesnt solve it then make sure you have the correct rad. cap. Also that the filling hose is not clogged as well as the little port on radiator.

Have you removed and tested the thermostat?
