    04 Chevy Aveo Heater Core Removal?

    The heater core started leaking recently in my gf's aveo and she was able to pick up a replacement heater core. So I get the fun task of swapping units.
    First off how do I begin pulling panels? Screws aren't very visible and some parts seem to pop off with clips, but there is very limited access.
    What all will I need to pull to reach the heater core? The casing which houses the heater core is visible but very tucked away and I honestly don't know how I'm going to get it out.

    Any tips pointers or advice is extremely appreciated!
    Thanks.

    According to the service manual the entire heater case has to come out of the car which involves the whole dash board. The job pays over 8 hours, it is very involved.

    good luck. thats all i can say. really nice thing is, is the hidden screws in the dash. you can barely get to them, and im sure most people probably just pry the dash out anyways. rather than facing forward like all the others, these actaully come in from behind on an angle, and are located by the a pillars, by the firewall, but inside the dash. another fine design by the fine people of GM. kind of like the rest of that car.
    There are no stupid questions, just stupid people.

    Did you disconnect the heater hoses, remove the refrigerant and disconnect the A/C hoses too? If there is a hose on the A/C drain that will need to come off also. I have never worked on an Aveo but there may be some fasteners under the hood.

    i find it hard to understand how a 2004 heater core could be bad.
    do heater cores usually last for longer than this?
    thanks

    my 1992 beretta lasted for 12 yrs then the new cheap one I put in lasted 4 yrs. I think things are made cheaper these days or I'm just getting to old?
