I walk you through replacement of the front heater core on a 2000... I just finished replacing the fuel pump and sending unit on my2000 Olds ..

It will require several hours of labor just to get into the heater core. Its not so much the heater core replacement, its taking most if not all of the panels underneath the passenger side underneath the dashboard. Dpending on your car model, it may also require you to remove the glove box just to have access to the heater core.

In rare cases you have to remove the whole top dash board but most cars in general only require to remove panels underneath the dashboard on the passenger side. It's tricky to remove the heater core because it is well hidden behind many panels, a whole lot of screws to remove. Then you have to remove or cut the heater hoses in front of the engine compartment as those hoses are attached to the heater core.

I just replace the heater core in my old buick and it took some effort to undo all those panels and hoses and screws but i finally got it all done and heater works perfect. That repair at a automovtive repair shop would of cost me 350 to 400 dollars. I just spent 35.00 bucks for the heater core and another 12.00 bucks for new heater hoses and that was it, that and the intense labor involved to remove the old heater core. But i saved a huge bundle by doing it by my self, good luck.

It's a long 7-10 hour job.

Have to remove the dashboard

then remove hoses to heater core
then remove wires going to heater core circuit board
then remove heater core
replace it and put everything back together without messing anything under your dashboard.

Mechanics charge between $700 to $1000 to replace one.

If the core is not leaking (wet passenger side floor) you may want to try a reverse flush before touching anything, remove the 2 hoses in the engine compartment at the firewall leading to the heater core and with a garden hose flood the heater core connector until it the water is clear then do the other connector.

If that don't work and your not sure you can do the replacement correctly don't do it.

Instructions

1. • Drain the Camry's engine coolant, using a clean container for reuse. Disconnect the negative battery cable and wait a minute and a half for the airbag system to de-energize. Discharge and recover the air conditioner refrigerant.
     
   • 2Disconnect air conditioner suction hose and liquid pipe, then clamp on the tubes with an SST clamp. (Make sure you don't deform the tube). Disconnect the heater core hoses.
     
   • 
     
   • 3Disassemble every component of the dashboard, starting with the steering wheel and column. Removal includes the door scuff plates, cowl side trim, console panels and air bags. You'll need a second person's help to remove the dashboard from the interior.
     
   • 4Remove or disconnect all air ducts, the heater blower assembly, lower defroster nozzles, air conditioning radiator assembly. Remove the mode damper servo sub-assembly and Airmix damper servo sub-assembly, then remove the core from the air conditioner assembly.
     
   • 5Install the replacement heater core into air conditioner assembly. Reassemble all components of the heating/air conditioning unit, dashboard and dashboard components. Connect the heater core and A/C suction and pressure hoses, lubricating the O-rings with compressor oil.
     
   • 6Attach the negative battery cable, fill the cooling system and evacuate and recharge the air conditioner. Start up the engine and check for leaks in the system.

   Detach the heater core hoses at the firewall. The two black hoses attach near the firewall on the passenger's side of the engine compartment. Squeeze the hose clamps on the end of the hoses with pliers and slide the hoses from the heater core tubes.
   
   

   • 4Remove the lower passenger's-side and driver's-side dashboard panels. The two panels are held in with push-pins. Raise the center of the push-pins with a small, standard screwdriver and pull the pins from the panels. Pull the panels away from the dashboard to separate them from the dashboard.
     
   • 5Remove the center console. Separate the gear select trim piece from the center console, using a small standard screwdriver to pry the trim piece from the center console. Lift it over the shift knob and rotate it to clear the knob. Remove the retaining screws holding the center console in place with a Phillips screwdriver. Lift the console up over the shift knob and remove it from the interior.
     
   • 6Remove the glove box. Open the door to the glove box. Squeeze the two retaining tabs on the ends of the glove box and pull the glove box away from the dashboard. Remove it from the interior.
     
   • 7Detach the drain tube from the heater core cover, which is located behind the glove box. The tube can be pulled from the heater core cover by hand. Detach the air intake duct from the bottom of the heater core cover. The air intake duct runs from the bottom of the cover to the center of the dashboard. Remove the duct by hand.
     
   • 8Remove the retaining screws on the black heater core cover with a Phillips screwdriver. Pull the cover from the heater core and remove it from the interior. Remove the heater core clamp screw with a Phillips screwdriver, pull the clamp away from the heater core, then pull the heater core from the housing.
     
   • 9Place the replacement heater core against the housing. Place the clamp over the heater core and install the clamp retaining screw with a Phillips screwdriver. Position the heater core cover over the heater core and install the retaining screws with a Phillips screwdriver.
     
   • 10Attach the drain tube and the air intake duct to the heater core cover.
     
   • 11Install the glove box. Squeeze the retaining tabs on the sides of the glove box and push it into position against the dashboard. Release the tabs when the glove box is in position.
     
   • 12Install the center console. Guide the console over the shift knob and install the retaining screws with a Phillips screwdriver. Slip the shift selector trim piece over the shift knob and push it into the center console.
     
   • 13Place the lower passenger's-side and driver's-side dashboard panel in position. Install the push-pins into the retaining holes, pushing the in center of the pin to engage the pins.
     
   • 14Fill the radiator with coolant. Most climates require a 50/50 mix of DEXCOOL coolant and water. 2.2L engines require 8.6 qts., 2.4L
     

Instructions

1. • 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.

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.

Good luck.

The heater core is located behind the dashboard. The entire dashboard has to be completely removed in order to replace the heater core. The time it takes to remove and replace this dash is usually about a few hours, thus the high $500-$600 pricetag, which I believe is decent.
