Perhaps you could share the source of the procedure for bleeding the coolant with us? Still not shure what you bled.

This is the first report of a problem of this nature that has been reported on this site, so it may be more uncommon than you have been led to believe.

Has your Prius been involved in collision repair?
If so, you should have included this info in the beginning of this thread.
Or, are you that without any previous change to the cooling system since original purchase, that it needed bleeding? And how did you determine this?

 

The small motor you talked about- is it inside heater box assembly ..I have everything works fine except something wrong in heater box. The aluminum pipes are very hot. Blower working but cold air comes out. Any advice?
