Comments about CARQUEST Heater Core:

Unlike the oem core I took out, the replacement core has swiveling inlets that make it easier to install.

      Remove the heater core and the hoses from the heater core pipes by pressing
      the tabs together with pliers. Clamp the heater core hoses using the hose clamp pliers and pinching off the hoses.
