SOURCE: 1994 buick lesabre heater core removal

The heater core is located under the dash, in the center. The container holding the core looks like a black plastic box. Remove the ash tray for easier access. You may have to also remove some other covers under the dash. You must first drain the radiator then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that go thru the center of the firewall. Remove the screws that hold on the cover to the heater core. Then you should be able to get the old one out. There might be a couple of other minor steps but I'm sure you can figure them out. For re-installation just go in reverse order to put it all back together.

How to remove the heater core on 94 mercury cougar


Removing the Old Core
  • Disconnect the Mercury Cougar's negative battery cable. Remove the center console from the interior. Disarm the car's air bag system and remove the bag's diagnostic monitor and bracket.

  • Take the heater outlet floor duct out of the car. Remove the screw holding the air transfer duct and push it into the outlet duct. Unscrew the screws retaining the outlet duct to the heater core cover and release the retaining tabs on each side to remove the duct.

  • Raise and support the Mercury Cougar, using multiple jackstands. Drain the engine coolant by removing the drain plug on the bottom of the radiator. Replace the drain plug after all the liquid flows into a clean container and disconnect the heater hoses from the core

  • Withdraw the black vacuum supply hose from the vacuum source (you can now lower the vehicle). Disconnect the same hose from the air conditioner's vacuum reservoir tank.

  • Detach the heater core cover that holds the core by releasing the retaining tabs and removing the clips. Remove the dash panel seal, vacuum hose and heater core bracket from the cover.

  • Remove the heater core from the cover and the case seal from the core

Bypass the heater core in 94 Chevy cavalier


You need to take the two hoses off of the heater core. Remove one of the lines and hook the end of the other line that used to attach to the heater core to the fitting on the engine that the hose that was removed used to be attached to.

Feel the hoses going to heater core, one should be hot and the other warm. If one is cold or both are then heater core is clogged. Make sure heater control valve works and as vacuum to it and or the cable is free.

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!
