heater core change on 91 cutlass ciera
Does anyone have a detailed procedure to change the heater core on a 1991 Olds cutlass ciera 3.3L with AC? What’* the easiest way to get to the hoses on the firewall? Details on inside components to remove including screw locations. Pictures if you have any would help. Thanks, Ken

- drain the rad
- go under the dash and remove the kicker panels. There are 2 panels
- Once you do that you will see all the wirers and everything under the dash. In the center you will see what looks like an air duct. Start removing the panel that has the vents and remove the 2 black plastic hoses from the vent panel.
- Then after that you will see one last panel, the heating core is behind it.
- Once that panel is removed then you unscrew the 2 brackets that hold the heater core in place.
- Next you want to disconnect and remove the 2 hose clamps and hoses. They are located under the hood on the passenger side, under the blower motor going into the fire wall
- take the heater core out
