I was almost to work this morning when all my antifreeze spewed out! Looks like ot all wnt out the over flow hose in that clear tank. What would cause that? Thermostat? Water Pump?

 

Many things can cause that!! How long have you owned your Aerio, do you run your AC on in the winter, how long has it been since you check your AC, do you change your AC as required per the owers man. , do you have Auto or Man. trans, were youhighon rpms while going up hill changing gears, were you are at is it really hot or cold, did you hit something while driving in which could cause a check in your radiator? All of these are some factors in this issue. If you don't know have pep boys check it out or your dealership.

 

So could this be an AC issue...I have an 04 that is overheating only when the AC is on....Flushed the antifreeze and also change the thermostat...Neither one took care of the issue...Any clue on what could possibly be the cause and what would take care of it...I am so frustrated right now...
