I am replacing the heat core and the manual I have does not give much detail. Do I need to remove the dash and disarm the airbags to replace the heat core?
Do you
have the same problem?

Here are directions I was able to find. From what I read, the core can be removed from under the dash, not requiring the removal of the dash. However, I do recommend disconnecting the battery and allowing the vehicle to sit for about 30 minutes so there is no power left in the system. Any time I work around air bags, I do it. They can deploy if the wrong thing is done. Look through the directions and let me know if you have other questions. At the end is a picture of the heater core coming out.

1.Disconnect the negative battery cable.
2.Drain and recycle the engine coolant.
3.Raise and safely support the front of the vehicle.
4.If necessary, remove the rear lateral transaxle strut mount.
5.Detach the drain tube, then disconnect the heater hoses from the core tubes.
6.Carefully lower the vehicle.
7.Remove the console if equipped.
8.Unfasten and remove the sound insulators, console extensions and/or steering column filler, as required.
9.On some models it may be necessary to remove the steering column opening filler.
10.Remove the floor or console outlet ductwork and hoses.
11.Remove the heater core access cover.
12.Unfasten the heater core mounting clamps/bolts, then extract the heater core from the vehicle.

To install:

13.Install the heater core, then secure using the clamps/bolts.
14.Fasten the heater core cover.
15.Connect the outlet hoses and ducts.
16.Install the sound insulators, console extensions and/or steering column filler.
17.Raise and safely support the vehicle.
18.Install the drain tube and connect the heater hoses to the core tubes.
19.If removed, install the rear lateral transaxle strut mount, if removed.
20.Carefully lower the vehicle.
21.Connect the negative battery cable.
22.Fill cooling system and check for leaks. Start the engine and allow to come to normal operating temperature. Recheck for leaks and check coolant level. Add if necessary.
