SOURCE: Heater Core

My mechanic tells me it is almost impossible to get to it without
taking out the dash. This will give you the clearance you need
to replace it. You might try it from under the dash if you have a
good back but i don.t think there's enough clearance to get it out.
I bought a salvage 1997 lss Olds and the airbag popped the dash
so we had to replace it. Not an easy task unless you've done it
before.

Inspect/Replace If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing

  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

Were is the heater actuator vacuum line on the firewall.on the Olsmobile lss,1997?


Look for a black plastic ball on the firewall. This is the vacuum reservoir and the line coming to it is from the engine. The other line goes inside to actuate the controls.

Were is the heater door actuator,vacum lineon the firewall on an 1997 Olsmobile Lss


Said actuator is not on the firewall, it's on top of the heater/AC box on the inside under dash. That is what closes off the heater core for A/C.

Have to replace the heater core on a 1997 Pot.


This is a fairly easy fix. Disconnect the heater hoses under the hood. Go to passenger side under the dash remove the lower panel from the dash to access the heater box. Unplug any and all connections on the lower half of the heater box and remove the lower half of the box should be about six screws you should see the heater core and the evaporator core. Heater core skinnier of the two should have one or two straps holding it in remove the straps and remove the core and replace.
