SOURCE: 1983 cadillac eldorado,what i want to know is how

You need to remove the glove box. Remove the Programmer from the heater box. The heater box has studs going through the firewall attached with speed nuts on the UNDERHOOD side of the firewall . The nuts on the lower part of the box cannot be seen , so must be felt, and then removed. Place rags on both openings of heater core so as not to leak any coolant into the car. Heater box once unbolted must be artfully removed from UNDER the dashboard. Hope this helps

You dont have to remove the dash but it might make it a easier job if you did. The heater core is removed from under the R/S dash. after removing the lower dash covers, glove BOX, A/C programmer. Then from under the hood, disconnecting heater hoses, and removing heater case mounting bolts.Then finally jockying the heater box from under the dash without spilling coolant fronm the heater core is a trick. Hope this helps.

you cannot bypass this under the hood> You will have to get at it from underneath the car> If you can find an adapter that will connect the two different hose sizes together than you can do it that way> otherwise not much else you can do besides JB underwater weld and cement the cracks>

Not sure if this will help but this is on a 2001 Eldo which should be close to what you have. I would also suggest the library and check out a Chilton's repair manual for you car.

My heater dont get hot it just blows cold


Sounds like the heating core you may have to take it to a mechanic who knows how to service a Cadillac or your next bet would be to take it to a dealership. Spendy, but I would rather have a certified mechanic check on the caddy then a back yard mechanic

How to remove the heater core


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.

Need to replace heater core


Very very big job. Only do this if you really really love your car. Here is the 100ft overview:

*Disconnect the heater hoses at the heater core inside the engine compartment. (recommend cutting the hoses and replacing with new ones)
*Disconnect the heater valve cable from the heater valve
*Remove dashboard (involves removing steering wheel/column, radio, glove comp, etc)
*Remove the heater assembly (big black plastic box behind the radio)

The core is inside the heater assembly.

Again, this is a big job, and it will probably be very frustrating at times (I know from experience). If you do not have a repair manual for the car and you think you want to try this...get the manual first!
