    Have the air conditioning system discharged. Because you are dealing with refrigerant contained at a very high pressure, this must be done by a professional at a dealer service shop or air conditioning shop.




    Remove the instrument panel (dashboard) from the vehicle. With the steering wheel in the "Lock" position, pry off all scuff plates, kick panels, trim panels and center console. Disconnect all ground cables and electrical connectors. Remove the passenger airbag and pry out the defroster grilles, then remove all screws mounting the panel and lift the panel out with an assistant's help.


    Disconnect the heater hoses and the evaporator lines at the firewall by squeezing the connectors' plastic tabs, then plug the open lines with rubber. Disconnect the main vacuum line and remove the demister tube, which looks like a vacuum tube with a square, bristled end.


    Unscrew the screws holding the bracket above the heater core housing and remove the bracket. Take off the heater core cover by removing its screws, then pull the core out, making sure you don't tear the foam material surrounding it.


    Install the new heater core into the housing, making sure the foam material is intact. Place the cover and bracket back on the core and reapply the mounting screws.


    Reconnect all the lines to the firewall, using new retainers and O-rings on the connectors. Reinstall the entire instrument panel, refill the coolant, connect the battery system and have the air conditioner recharged.

SOURCE: heater core replacement

It's one of the easiest cores to replace that I have encountered. Disconnect heater hoses at firewall. Probably doesn't matter about hose placement, but I always mark them just in case. To remove the fiber cover under dash, take a flat blade screwdriver and pry out the center pin of the expansion clips that hold it in place. There are four 5/16 head screws that hold the bottom/drain tray cover. Core will pull through the firewall and then down. You may have to silicone/glue or replace the foam seal strips on the new core. Before you install the core, check the distance between the inlet and outlet tubes to ensure they match the openings in the firewall. This saves time. It helps if you have someone on the outside to guide you when stabbing the tubes through the firewall. Replace bottom cover. You may have to hold one of the tubes when reinstalling the first hose to the core. Replace any lost coolant and check for leaks prior to reinstalling the fiber cover. If the cover seal is in good condition, any leak should drain through the firewall, otherwise it may leak inside cab. .

It's a big job. Drain the coolant down, recover the freon in the ac system and disconnect the lines and heater hoses. Lower the steering column, remove the instrument panel assembly, remove the heater housing. Split the case halves on the housing and there you are. Usually around 500 to 700 dollars at a dealership.

SOURCE: how to replace heater core in 98 ford expedition

Heater core is a lot of work, but not extremely technical. You do have to remove the console, if applicable, and most of the passenger side dash materials, until you can get to all the small bolts on the bottom of the black blower unit. Beware of all the blend doors, they have to go back in the right places!. Then, to get the old core out, you may want to cut the metal tubes of the heater core, so you can work loose the hose connections to fit the new one. Strongly recommend Ford OEM replacement core, about $110, for fit. Also check closely the bottom of the blend door axle for cracks, you may want to replace it (about $35) while you are there. Local A/C shop with good reputation quotes $350 labor for this job. Good luck!

Heater coil on a 1999 ford expedition how hard is it to change out?


Inspect/Replace 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 ford expedition 1999


My friend you do have a biggy! You will need a helper to remove the bolts. The bolts have nuts that need another to hold. But you will need to remove the glove box to get to them. Be very careful, as there is always a hidden screw. Do replace the heater hoses at the same time!
Expect a full day to replace this core!

Heater core replacement 1999 expedition


Heater Core 1. Disconnect the battery ground cable 2. Drain the engine coolant. 3. Remove the instrumental panel. 4. If equipped with the 5.4L 4V engine, remove the junction block splash shield. 5. If equipped with the 5.4L 4V engine, remove the bolts and disconnect the cable ends from the starter relay. 6. If equipped with the 5.4L 4V engine, remove the junction block bracket. 7. Disconnect the heater core hose couplings. 8. Remove the retaining screw and remove the A/C plenum demister adapter. 9. Disconnect the vacuum line from the A/C plenum demister adapter. 10. Remove the heater core bracket. 11. Remove the 13 plenum chamber top retaining screws. 12. Remove the plenum chamber top. 13. Remove the blend door assembly from the case. 14. Remove the heater core. 15. The installation is the reverse of the removal.
The heater core should be encased in a box up inside the dash.The best way to find this is to locate the heater hoses that go through the fire wall(about 1 1/4 in diameter).This is a very tight job and you will spend most of you time laying on the floor taking out screws.Be careful not to loose any of the heater core casing screws or bolts and when refilling the coolant system fill the radiator directly,start the engine with the radiator cap off,the level will drop,fill the radiator the rest of the way and replace the cap,allow the engine to reach normal operating temp.(about 10 to 15 minutes)so that the themostat will open and then allow the engine to cool and recheck fluid level.
