Heater Box Removal To Replace Heater Core

Understand the dash has to be removed in order to get Heater Box out and replace faulty heater core. Trouble is the heater box just doesn't seem to want to move from firewall. Are there any hidden screws that must be undone? Is there some other trick that I need to know?

2007 g6 pontiac heatercore removal step by step or do i have to remove dash


Some of the dash will have to be removed in order to remove the heater box assembly. In most cases, the air conditioning will have to be evacuated/recharged as the AC evap core is also in the same box as the heater core. This has a labor time of 5.9 hours to complete a heater core replacement. Not a job to attempt with out mechanical back ground

Why must i discharge the air conditioning refridgerant prior to removal of the heater core on a 2003 c230 mercedes 1.8l coupe.


The reason in why you must evacuate the a/c system with an a/c machine before you can remove the heater core is because the evaporator is located inside of the heater core box assembly. So before the heater core box assembly can be removed the a/c system must be evacuated then you can disconnect the a/c lines that go through the firewall to the evaporator.

How do I change my heater core in my 1996 ford ranger


The heater core is located in the heater box, under the passenger side of the dash. Most FORD heater boxes are snap-clipped together, and if you remove the rear panel from the heater box, you will see the heater core...it looks like a smaller radiator...twist the heater hose off of the heater core (x2) from the engine side and gently remove the heater core from under the dash. When replacing the new heater core, be very careful re-installing new hoses to the core...it is a fragile thin metal that can leak almost instantly if tweaked too roughly...replace all parts in reverse order of removal.

Replace heater core


Instructions
    • Drain the cooling system. Draining the cooling system will prevent toxic engine coolant from leaking into the passenger cabin of the vehicle during removal of the heater core. To drain the cooling system, simply disconnect the lower radiator hose from the radiator by loosening the hose clamp and pulling the hose off. Be sure to drain the fluid into a sealable container and dispose of the coolant at an appropriate disposal site.
    • 2Pull the dashboard six inches rearward. In order to do this, you must remove the following parts; the center dash bolt (located under the defroster vent cover), the bolts under the driver and passenger kick boards, the bolt connecting the dashboard to the radio mount, and the the bolt connecting the dashboard to the rear of the glove box. The locations of these bolts are immediately apparent upon looking under the dash. Once you have removed these bolts, you can pull the dashboard rearward and secure it.
    • 3Remove the heater core box. The heater core box is a black plastic box that surrounds the heater core. This part should be visible when looking down into the dashboard from the passenger side seat. Remove the two bolts on top holding it to the firewall and another on the bottom near the foot well. After removal of these bolts, the heater core and box are attached to the vehicle only by the coolant lines, which you can now disconnect by reaching into the box and pulling them off of the heater core (you may have to loosen the clamps first).
    • 4Install the new heater core. This is accomplished by applying steps 1 through 3 in reverse order; re-connect heater core coolant line, re-install heater core box (be sure to apply silicon sealant to the edges of the box, hermetically sealing it), replace the dashboard and install bolts, and re-fill the cooling system.

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.

Leaking Heater hose or Core


REMOVAL & INSTALLATION
Disconnect the negative battery cable.
Position a drain pan under the radiator, open the drain **** and drain the cooling system to a level below the heater core.
NOTE: Plug the heater core tubes to avoid spilling coolant in the passenger compartment during removal.


Disconnect the heater-to-engine coolant hoses from the core tubes on the fire wall, in the engine compartment.
NOTE: On some early model vehicles, the cabin light mounted under the dash may interfere with cover removal. If necessary, loosen the retaining bolt and reposition the light housing with the wiring attached.


From the passenger compartment (under the dash) remove the heater core rear case cover-to-cowl screws, then remove the cover from the vehicle.
NOTE: On a few of the early model vehicles covered by this manual, some of the heater core cover screws may be partially/fully covered by the dashboard. Be sure that all are removed before attempting to remove the cover. If necessary, unbolt and reposition all/part of the dashboard for better access.


Remove the straps or brackets from each end of the heater core.
Carefully remove the heater core from the cowl and case.
Installation is the reveres of removal. Run the engine at normal operating temperatures and check for leaks
