You'll have to remove the dash in layers. The heater box is the last thing you actually get to. It's not a fun job. It's a very time consuming job. I believe "book" time on that job is around 8 hours. Even guys like me that have done these before take longer that what "book" times is.

SOURCE: How to remove dash panels...need to replace heater core

You need to buy a repair manual first. You must have the feon removed, because you must disconnect the AC lines from the evaporator, It took me about 4 hours. The screws are under the dash at each end plus in the middle there is a support brace bracket.

Under the dash for sure, but you may need to drop the whole box and may be mounted with bolts from the engine compartment. You will need to disconnect the hoses from the core from under the hood

If the dash is removed you've saved about 9 10ths of the job endurance. Look around, what you believe to be, the perimeter of the heater box. I cannot, and no one else can, tell you exactly where the bolts and nuts that mount the heater box are. Therefore you must viually sixe the box and check outide in the engine compartment and inside under the dash for the mounting bolts.You'll want to start by removing the heater hoses. Then starting at the passenger side engine compartment look for a group of 10mm or 7/16ths nuts retaining the housing and remove them. Do the same inside. The housing is usually held together with screws or clips, it changes year to year. Keep a log or pix of the wires and cables and hoses(vacuum) that are connected to the housing for reassembly. You'll need to "roll" the box out from under the dash depending on how much of the dash has been removed. The core is easy to spot for is has two hoses sticking out, and, is encircled with clips or screws . Also make sure you remove the bracket around the two entry hoses if it has one. Thank you, Dana

HOW DO YOU REMOVE THE HEATER CORE IN A 1992 ISUZU TROOPER


You must remove the complete heater core and a/c evaporator from under the dash. It goes from the center of the dash to the passanger side of the dash. You have to remove the glove box, remove the heater hoses, vac. lines to the controlers. Bolts that hold the unit to the firewall. Also must remove small vents at bottom of the dash. Would be much easier if you would just tell me what area you are having problems with. After you are done you will have to recharge your a/c system. This is not a job for a novice.

Im replacing the heater core in 2001 jeep cherokee...i have the dash off down to fire wall...all screws are out of bottom heater box but I cant remove the bottom of box to get to heater core...what am I...


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.

Heater Core - REMOVAL & INSTALLATION
1994-97 Vehicles
(see Figure 1)

44d2ba8.jpg

Fig. 1: Exploded view of a common heater core and case assembly
  1. Disconnect the negative battery cable and properly drain the engine cooling system to a level below the heater core.
  2. Disconnect the heater hoses from the core tubes near the cowl.
The instrument panel carrier is designed not only to provide access to parts through removal of the carrier components, but the carrier will also tilt downward as a complete assembly to allow access from the top. If this is desired, remove the retainer screws along the top and bottom of the carrier assembly (refer to the figure). The instrument panel will then tilt as an assembly into the cab. It is necessary to unbolt and lower the steering column from the carrier to allow for maximum movement of the instrument panel.
  1. The instrument panel must be removed or repositioned for access to the heater core case. Unbolt and either tilt the instrument panel forward or disengage the instrument panel components and remove the panel from the vehicle. In most cases, tilting the panel forward should be sufficient for the necessary access.
  2. Unfasten the heater core rear case retaining screws, then remove the rear case for access to the heater core.
  3. Loosen the retainers and remove the heater core retaining straps.
  4. Remove the heater core and seals.
To install:
  1. Install the heater core and seals, taking care not to damage the core tubes when inserting them through the cowl.
  2. Install and secure the core retaining straps.
  3. Install the rear case and secure using the screws.
  4. Reposition and secure the instrument panel and components. Tighten the cowl screws to 17 inch lbs. (1.9 Nm) and the lower instrument panel screws to 66 inch lbs. (7.5 Nm).
  5. Connect the heater hoses to the core tubes.
  6. Connect the negative battery cable, then properly refill the engine cooling system.
  7. Run the engine at normal operating temperature, then check for leaks.

Good luck (remember rated this post).

1993 taurus heater core replacement guide


This is a big job which involves discharging and removing parts of the A/C system as well as removing parts of the dash. I had the core done on a 94 Sable years ago and it was a very labor intensive and expensive job. Here are some instructions I found for a 94 Taurus which should be the same thing or similiar, but I don't guarantee that. Please note that these instructions were not tested by me and may contain errors or be incomplete in some way. For example "remove instrument panel" sounds simple but in reality is a process in itself requiring the removal of many screws. Naturally you would have to recharge the A/C and refill the coolant when done.
__________________________________________
Removal

1. Remove instrument panel and lay it on front seat.
2. Remove A/C evaporator housing as outlined.
3. Remove vacuum source line from heater dash panel seal (18529).
4. Remove heater dash panel seal from heater core tubes (refer to Heater Case Assembly).
5. Remove four heater core access cover retaining screws and remove heater core cover (18B300) from A/C evaporator housing.
6. Lift heater core and seals from A/C evaporator housing.
________________________________________________
Installation

1. Transfer three foam core seals to new heater core.
2. Install heater core and seals into A/C evaporator housing.
3. Position heater core cover on A/C evaporator housing. Install four retaining screws.
4. Install heater dash panel seal on heater core tubes.
5. Install vacuum source line through heater dash panel seal.
6. Install A/C evaporator housing into vehicle as outlined.
7. Reinstall dashboard components.

Best of Luck!

98 intrique heater core out


your right. i just finished 5 minutes ago pulling my heater core out, 1999 Intrigue. If you are good you might be able to loosen the dash, push the bottom back and up and pull off the covers over the heater core for removal, not sure. i didn't have a manual so i pulled the complete console, complete dash, removing all electronics one at a time, remove top cover to get access to the top bolts, pull the rubber door trim from the side to get to 2 13mm head bolts on each side, the metal plate under the steering wheel must come out too, unhook all lights, switches, cig lighters, etc. phisicallly remove the complete dash. then pull off the bottom pieces, 3, of the black box, which holds the heater core. lots of little bolts around the edges, and one holding the heater core pipes. don't loose any of the thousand bolts. have fun.
