Replace heater core


Instructions
    • Drain the cooling system. Draining the cooling system will prevent toxic engine coolant from leaking into the passenger cabin of the vehicle during removal of the heater core. To drain the cooling system, simply disconnect the lower radiator hose from the radiator by loosening the hose clamp and pulling the hose off. Be sure to drain the fluid into a sealable container and dispose of the coolant at an appropriate disposal site.
    • 2Pull the dashboard six inches rearward. In order to do this, you must remove the following parts; the center dash bolt (located under the defroster vent cover), the bolts under the driver and passenger kick boards, the bolt connecting the dashboard to the radio mount, and the the bolt connecting the dashboard to the rear of the glove box. The locations of these bolts are immediately apparent upon looking under the dash. Once you have removed these bolts, you can pull the dashboard rearward and secure it.
    • 3Remove the heater core box. The heater core box is a black plastic box that surrounds the heater core. This part should be visible when looking down into the dashboard from the passenger side seat. Remove the two bolts on top holding it to the firewall and another on the bottom near the foot well. After removal of these bolts, the heater core and box are attached to the vehicle only by the coolant lines, which you can now disconnect by reaching into the box and pulling them off of the heater core (you may have to loosen the clamps first).
    • 4Install the new heater core. This is accomplished by applying steps 1 through 3 in reverse order; re-connect heater core coolant line, re-install heater core box (be sure to apply silicon sealant to the edges of the box, hermetically sealing it), replace the dashboard and install bolts, and re-fill the cooling system.

Instruction on how to replace heater core on 2000 olds bravada


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 instructions on replacing the heater core in a 1998 oldsmobile bravada?


This is probably the same as it is on the S-10 truck. You'll have to remove the dash to get to the heater core box. Drain the coolant and locate the two hoses on the engine side of the fire wall and remove them. There are large electrical connectors under the dash that have to be unplugged. Remove the large bolts/nuts holding the dash to the frame and drop the steering column to ease removal of the dash. You'll be able to see the heater core box now. Remove the bolts hold it to the firewall and there are also bolts on the engine side of the firewall holding the box in. This is where it gets frustrating. Remove the blower motor resistor that is mounted in the engine bay and inside that hole is another bolt holding the core box in place. With all of the bolts out you can pull the case apart and replace the heater core. Put it all back together and fill the cooling system. Start the vehicle and run the heat on full. Leave the radiator cap off so air can escape. Watch the coolant level and add as needed until the engine reachs normal operating temperature and put the radiator cap back on. The last one of these I did I charged $450 to do plug parts. His next best quote was $950.

Heater core removal 2000 oldsmobile bravada


i belive there is what looks like t perferated line in the plastic where the heater core is that you are suposed to cut to gain access to the heater core. i have never done this but i know several people who have you just need to make sure you get the access door resealed if you go that route or it may affect your heat. remember if you remove the dash instead of the other method you will have to have the a/c system emptied since it also circulates through that box.

Low heat from heater


Had same problem. Take off both hoses to the heater core at the fire wall. Using a garden hose with nozel flush with water on the "inlet hose" first(the one hot to touch) then flush the other side. A nasty blackish slim will come out. Oh, cover your distributor with a plastic bag first so it won't get wet. Put the hoses back on, set heat for full high and enjoy your nice warm bravada again!
