SOURCE: heater core

HI. This is not an easy job but, im sure you will be able to accomplish this with a little guidance. I have put together a guide for you to follow. Its a step by step guide and, it will help you with this replacement of your heater core.


REMOVING THE OLD CORE--

#
Step 1

Jack up the car and drain the Impala's cooling system. Loosen the water pump's drain bolt and let the coolant drain into a pan. Close the drain bolt and lower the car afterward.
#
Step 2

Remove the heater outlet and inlet hose from the heater core (reposition the hose clamps to do so). Take off the right console extension panel, body control module and left side extension panel on the front floor console
#
Step 3

Disconnect the left instrument center support bracket (pull away the carpet at its bottom to reach the nuts). Remove the accelerator control pedal from its position in the front of the dash.
#
Step 4

Disengage the center floor ducts by raising the outlet duct while pushing the ducts down. Rotate the outlet duct forward in the car and pull down to remove it from the HVAC module.
#
Step 5

Use a small chisel to remove all the heat stakes from the heater core cover. Loosen the nut behind the fuel line bracket. Remove the dash panel's stud at the heater hoses.
#
Step 6

Pull the core's cover down enough to reach the HVAC module's locating pins. Slide the cover rearward until the drain tube clears the dash front. Remove the cover by sliding it down, rearward, and to the right. You can now remove the core.
Installing the New Core


INSTALLING THE NEW CORE---

#
Step 1

Install the new core into the HVAC module, attaching a new seal onto the drain tube. Attach the core cover from the right side, sliding it up and forward into position.
#
Step 2

Align the drain tube with the front dash hole and the core cover holes with the HVAC locating pins. Install the core cover screws, cutting and folding back the sound insulator near the center screw to ease that screw's installation.
#
Step 3

Reinstall the dash panel stud at the heater hoses, tightening the nut behind the fuel line bracket. Align the center floor duct with the HVAC and push it up while rotating rearward to install it. Put the floor ducts and outlet duct back into the Chevy Impala.
#
Step 4

Attach the accelerator control pedal. Pull the carpet back and position the left center support bracket, then tighten the bracket nuts.
#
Step 5

Reconnect the left side front floor console extension panel and the body control module to the car.
#
Step 6

Put on the outlet hose and inlet hoses to the core, securing them with their clamps. Refill the cooling system with the proper mixture of water and coolant.


Inspect the foam seal for the core on the lower HVAC case. Replace it with adhesive black foam tape if damaged.

Please rate and have a good day:)

SOURCE: 2005 impala instruction to remove heater core

oh, sucks for you!! i just replaced mine. it was a total pain in the ***. make sure you run the car up on some car ramps. this will help you quite a bit. because there will be times you'll be standing on your head, and in some horrible positions. it takes time and it takes patience. also make sure you have the correct heater core before you start. thanks to autozone, i drove around for about 3 days with the dash tore apart and the heating system bypassed because they gave me the wrong one. my recomendation is take your time. taking apart and putting together. 1/4 in drive metric set is handy to have. im no mechanic, however im also pretty handy and very mechanically inclined. i'd say with taking apart and putting together it probably took around 9 hours. but i was also by myself. lots of dash taking apart. and my car also has the center console, which didnt help my case. good luck!!!!!

Check the relays, fans, change the thermostst, now about to the change heater core. it sill was over heating and water came from the heater core on to the floor board.


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.
