    Thanks for your reply. I don't understand why they had to engineer the heater core and put in behind the dash. Could'nt they put it just 4" down or so?!?!??? This should be a fun project! How do I give you a positive feedback? Thanks, Nick
    Expert:  George H. replied 5 years ago.

    Welcome to the eternal question of automotive technicians all over the world "what was the engineer thinking and why does he hate me so much" LOL!!! You can get a shop to recover the AC system and recharge it properly when you are done with the core. They should not charge much to do this.

     

    When you accept the answer a dialog will open for bonus and feedback to be entered as you determine what my service was worth to you.

     

    If you have questions please ask
