SOURCE: heater core replacement of 1995

If your truck has air conditioning you drain the radiator and disconnect the heater hoses on the right of the engine at the firewall.get in the cab on the passenger side and remove the grove box for better access than remove the seven screws that holds the cover on remove the vacuum source but leave the vacuum harness attached to the cover and remove the cover than remove the heater core from its chanber.Now all you have to do is put every thing back in place.

SOURCE: blown heater core in a 1977 ford f-150 pick-up

1976-79 Without Air Conditioning

  1. Disconnect the temperature and function control Bowden cables from the heater housing. This must be done to prevent damage to the cables.
  2. Disconnect the wires from the blower resistor.
  3. Remove five screws attaching the air inlet (vent) duct to the heater housing.
  4. Disconnect the blower wires.
  5. Drain the radiator and remove the heater hoses from the heater core.
  6. Remove three heater stud retaining nuts and remove heater.
  7. Remove gasket between the heater hose ends and the dash panel at core tubes.
  8. Remove heater core cover and gasket (four screws).
  9. Pull heater core and lower support from heater.

To install:
  1. Install foam gaskets on heater core and install in heater assembly.
  2. Install the core seal and cover plate.
  3. Position heater assembly in vehicle and install three stud retaining nuts.
  4. Connect heater hoses to heater core and fill radiator.
  5. Connect blower motor wires.
  6. Place defroster nozzle on heater so that the defroster and heater openings are in the up position, and there is no air leak around the seal.
  7. Install air inlet (vent) duct to heater. Push duct firmly against seal on side cowl and tighten five attaching screws.
  8. Connect wires to blower motor resistor.
  9. Connect temperature and function control cables to heater, and adjust the cables.
  10. Reinstall gasket between the heater hose ends and the dash panel at core ends.
  11. Fill Cooling System.

Sounds like the blend door isn't working. Check for a vacuum leak.

1998 ford f-150 4.6L blows only cold air.


I have a 94 f-150 and i just replaced the heater core while i was doing this i noticed the controll cable/assembly for the blower duct door was exposed and easy to get to after taking off the glove box and the cable did indeed come off during the heater core fix this wire connects to the hot/cold knob on the dash check that out it could be loose or something its the only thing i can think of besides a bad heater core which would be characterized by steamy windows with heat on or just a puddle of coolant on the passenger side floor hope this can help!

My ford 1997 F-150 4.6L has a antifreeze smell in the cab when it is running, think it might be the heatercore?


yes it sounds like it might be the heater core when your heater core goes bad it leaks and seeing that it is in the cab it will have that smell usually when it leaks your floors will be wet from the leak. bypass the heater core unitl you can get it fixed to prevent any electrical problems

Heater core


email me at fordtech2005@gmail.com and I will be happy to email you pictures on how to do it. the flat rate labor time to do this repair is 7.5 hours which basically means that the whole dash must come out, also you will need to disconnect your a/c system to remove heater core.
