Have 2002 Kia Sedona, I did away with the lines and replaced them with heavy duty heater hose.
Stap the hose to the frame. Works fine!

Location of heater hose on 1998 plymouth grand voyager se


The heater hoses run to the backside of the motor and connect to the heater core on more towards the drivers side of the firewall. If you have rear heat there will be two metal lines that run under the vehicle on the passenger side. Those lines will connect to two rubber hoses that are attached to the rear heater lines that make there way to the rear heater core and connect just in front of the passenger rear tire.

Replacing rear heating coil in a 2003 Chevrolet suburban


i am assuming you mean heater core, you have to remove the pass rear cargo trim panel and any trim that interlocks to it as well as any connectors then the heater box and hoses from under the vehicle as well as if it has rear ac the ac system needs to be discharged first and those lines removed as well, then remove the box from the vehicle and seperate the case halves and replace the core, the reinstall in the reverse order of removal

A call to the dealership should be able to get you the official name but I would desribe them as the rear heater core lines. These lines basically supply heated engine coolant for the rear heat. A dealership parts dept can pull up a diagram of the vehicle based on the VIN number and give you the exact name and part number.

Hi, this is the heater core for your rear heater. If it's leaking from inside the box, it's likely the core is bad. Please let me know if you would like instructions for replacing the rear heater core. A new core is $92 at autozone, but I would shop around. Make sure you specify the rear or auxiliary when ordering a new new core, as the front core is different.

Good Morning, I have a Ford E150 1995 with rear air conditioner. I have seen anti freeze on the ground by the left rear tire. Is that a metal line or rubber hose. Thanks for your any help you can give me.


The plumbing to the rear heater is metal lines under the body and then connect with rubber to the core in the heater, with the age of the van the leak is most likey the metal lines corroded. If you don't need the rear heater operational, the lines can be by-passed in the front of the van [ it will not affect the cooling system].

Rear heater core lines leaking near firewall


If the tubes going to the rear heater core are the problem , drain the system and replace the bad tube/tubes. If the actual heater core is leaking and you do not want to go to the expense of replacing it, unhook both tubes at the back of the motor , cut out a good section of hose and use it to loop/connect the outlet line and inlet line on the motor side (not the rear heater core side). This will bypass the rear heater core , the front heater core should be adequate to heat the whole car. If you have a pin hole in a section of solid (copper) tubing, you can cut out the bad section and reconnect it with some heater tube and two hose clamps.

I need info on the replacement of metal heater lines that go from heater core in front along firewall to metal lines that go rearward to rr heater core on van with frt and rr heat/air.


Not sure what information you need, but before you spend a lot of time call the dealer and give them your vin number. It does not matter how many owners, but there was a recall on those lines around that time. If yours is one of them they will replace the whole set of heater and air conditioner at no charge to you.

THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN AN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
  • REVIEW THE WARNINGS AND CAUTIONS IN THE FRONT OF THIS SECTION BEFORE PERFORMING THE FOLLOWING OPERATION. See: Heating and Air Conditioning\Service Precautions
  1. Remove the HVAC housing from the vehicle. See: Heating and Air Conditioning\Housing Assembly HVAC\Service and Repair
  2. Remove the foam gasket surrounding the core tubes. NOTE: Notice the orientation of the irregularly shaped gasket on the tubes. The gasket must be placed correctly to ensure proper sealing against the body during reinstallation
    1. Remove the screws and retainers that secure the heater core and tubes to the HVAC housing.
    2. Remove the mode door actuator if necessary for clearance to remove the core.

      INSTALLATION

      WARNING: REVIEW THE WARNINGS AND CAUTIONS IN THE FRONT OF THIS SECTION BEFORE PERFORMING THE FOLLOWING OPERATION. See: Heating and Air Conditioning\Service Precautions

      Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold.

      High pressures are produced in the refrigerant system when the air conditioning compressor is operating. Extreme care must be exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose refrigerant lines at least once a year to make sure they are in good condition and properly routed.


      1. When installing individual tubes, insert tube into core ensuring that tube O-ring is seated in core and not pinched. Hold tube in seated position while installing the round tube-to-core clamp. NOTE: The round tube-to-heater-core clamp should be left loose enough to turn the tube in the core. Position the core in the housing, and then tighten the tube-to-heater-core clamp after orienting the tubes to the molded HVAC housing.
      2. Lower the heater core into the HVAC housing.
      3. Install the mode door actuator, if removed from housing for core removal.
      4. Position the retainers over the heater core tubes. Install and tighten the screws that secure the heater core and retainers to the HVAC housing. Tighten the screws to 2.2 Nm (20 in. lbs.) . NOTE: The grounding strap is to be attached to the lower heater core tube retainer.
      5. Reinstall the HVAC housing to the vehicle. See: Heating and Air Conditioning\Housing Assembly HVAC\Service and Repair

    1. Position the HVAC housing to the dash panel. Be certain that the evaporator condensate drain tube and the housing mounting studs are inserted into their correct mounting holes.
    2. Install the HVAC housing mounting nuts to the studs on the passenger compartment side of the dash panel. Tighten the nuts to 4.5 Nm (40 in. lbs.) .
    3. Connect the HVAC housing wire harness connectors.
    4. Reinstall the rear floor heat ducts to the center floor heat duct outlets.
    5. Install and tighten the nuts onto the HVAC housing mounting studs on the engine compartment side of the dash panel. Tighten the nuts to 7 Nm (60 in. lbs.) .
    6. Reinstall the PCM to the passenger side dash panel in the engine compartment. See: Powertrain Management\Computers and Control Systems\Engine Control Module\Service and Repair
    7. Reinstall the coolant reserve/overflow bottle to the passenger side inner fender shield. See: Engine, Cooling and Exhaust\Cooling System\Coolant Reservoir
    8. If the vehicle is equipped with the manual temperature control system, connect the HVAC system vacuum supply line connector to the tee fitting near the heater core tubes.
    9. Unclamp/unplug the heater core hoses and tubes. Connect the heater hoses to the heater core tubes and fill the engine cooling system. See: Engine, Cooling and Exhaust\Cooling System\Service and Repair
    10. Unplug or remove the tape from the suction line and the evaporator outlet tube fittings. Connect the suction line to the evaporator outlet tube. Tighten retaining nut to 28 Nm (250 in. lbs.) .
    11. Unplug or remove the tape from the liquid line and the evaporator inlet tube fittings. Connect the liquid line to the evaporator inlet tube. Tighten retaining nut to 28 Nm (250 in. lbs.) .
    12. Evacuate the refrigerant system. See: Refrigerant\Service and Repair
    13. Charge the refrigerant system. See: Refrigerant\Service and Repair
    14. Install the instrument panel in the vehicle. Refer to: Body and Frame, Interior Trim, Dashboard/Instrument Panel, Service and Repair, Instrument Panel Service Procedures, Instrument Panel Assembly Replacement, See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Procedures\Instrument Panel Assembly Replacement
    15. Connect the battery negative cable.
