to changing the Heater CoreBasically you pop the hood and to the very back left corner, you will see two hoses going into a box looking thing against the firewall. You will see numerous bolts and screws. You must tear that apart to get to the heater core. First step is unclamping the two hoses. Once you've done that and gotten to the heater core its just like changing a radiator except smaller. You have to undo from the supports and hoses etc.... Somewhat simple, however lengthy and tedious. (May get really frustrating!)
