Yes, there is not an access hole that allows any other method. Start by disconnecting heater hoses, then remove dashboard ***'y. Not too bad on Jeeps. Then you may or may not have to remove the whole HVAC box depending on where the lid for the heater core cavity sits. Usually this whole box must come out to get heater tubes thru the firewall. Then you can take the cover plate off, unbolt the tiny screws that hold down the arms, and remove the offending core. Good luck, takes me a day or less, and I've done it for years. Worth the 400-600 plus that shops charge for this if you are not into meticulous work, tiny screws, and lots of crawling around inside a Jeep. Don't worry, you're not alone in this. Only a handful of today's cars can be re-cored without removing the dash, or at least setting it back on the seat (on a blanket) to gain access to the HVAC box. Hope this helps you make your decision. TT

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.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • 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.

How to replace heater core in a 1988 jeep cherokee?


Jeep Cherokee XJ Heater Core

Work for '92 models, but can use it like a reference guide.

Figure 1

  1. Disconnect battery ground cable, then drain cooling system.
  2. Disconnect hoses from heater core.
  3. If equipped with A/C, remove evaporator/blower housing as follows:
    1. Discharge A/C system, then disconnect hoses from expansion valve.
    2. Disconnect electrical connector and vent tube from blower motor.
    3. Remove console, if equipped.
    4. Remove lower instrument panel attaching screws, then the lower panel.
    5. Disconnect electrical connections from A/C relay, blower motor resistors and A/C thermostat.
    6. Disconnect vacuum hose from vacuum motor.
    7. Cut evaporator/blower housing to heater core housing retaining strap, then disconnect heater control cable.
    8. Pry retaining clip from rear of blower housing flange, then remove the three retaining screws.
    9. Working from engine compartment, remove evaporator/blower housing attaching nuts, then the evaporator drain tube, Figure 1.
    10. Remove right kick panel, then the instrument panel support bolt.
    11. Pull right side of dash outward, then rotate housing downward and towards rear of vehicle until studs clear dash panel. Remove housing from vehicle.
  4. Remove heater core to housing retaining screws, then the heater core, Figure 2.

Figure 2

Personally, I'd pressure test the cooling system then look at the heater core to see if it leaks. It may just be a loose clamp or leaky hose.

Also can check the forum jpmagazine.com

I hope help you; good luck (remember rated this).
