    how hard is it to change the white plastic part that the heater hose is connected to which looks like it threads into the firewall?

    That is probably the inlet or outlet for your heater core. It is usually integral with the heater core itself, and will require replacing the heater core. Not an expensive part, but a total PiTA to replace. If you are a novice, take it to a shop.

    The White "
    plastic part" Connector's that are Number #1 in the Diagram....are Quick Connect/Disconnect, from the Connection's coming out of the Fire-Wall, to Remove them you need a Heater Line Quick-Connect Release Tool, as the Connectors have four Tangs to Depress at the same time, with this Tool you Slide it over the Heater Line. Clamp Tool over line. Then Press Tool into the Connector to Release can buy this Tool at Most Auto Outlets, Auto Zone, O'Reily's etc....


    Here's a Video showing how this Tool Works,

    08 acadia appears to be fully loaded and we love it! she wanted a 3rd row option and i was so sour about the pick up, how it was sold to me, and the integrity of the dealership. But we rode with it and now it seems to have paid off... I swear when I get in it, it is a brand new truck! This thing is so beautiful and I didnt have to fight the dealer ship they worked with me and came up with a option that we wanted. It was the loaner truck about a year and they had to sell it at the beganing of the year so we got a good deal and dont fret I did pay for GAP insurance since my wife is such a bad driver and will surely hit something and we also got a 4 year or 50k full warranty...... pure badass. It is 466 a month a hundred higher but something that works and in the shape it is in and the work I have to do to it is worth it. Plus now at tax time I can plus to get a 99- 02 Trans Am I have a 94 GT Trans AM but love the late model more!!!
