  1. Remove the front dash panel by turning the lower screws in a counter-clockwise direction, then unscrewing the single bolt on the lip of the instrument cluster and pulling the panel out. Remove the rear wiper switch and the 4x4 switches, if applicable. Lowering the tilt wheel will allow the panel to be totally removed.
  2. Remove the radio, headlight switch module and glove box by turning their screws in a counter-clockwise direction.
  3. Remove the main dashboard by unbolting it at the front, between the windshield and firewall. There are six to eight bolts holding it in, and, once they are removed, the dash can be pulled away from the firewall. Be careful not to pull too much, as the wiring harness could become damaged.
  4. Drain the coolant system by turning the drain plug on the lower left corner of the radiator and allowing the fluid to fall into the drain pan. Uncapping the radiator can reduce the internal pressure.
  5. Remove the heater core hoses, on the upper left of the engine bay, by pinching their hose clamps with a pair of pliers and pulling them off. Some models will have screw-type hose clamps; turning them counter-clockwise will loosen them. Age and heat may have stuck the hoses to the core nipples, and the hoses can be cut right at these nipples if necessary. Leave enough hose to reconnect the new core.
  6. Unbolt the heater core's mounts with a socket wrench in a counter-clockwise direction. Once the bolts are free, the heater core can be maneuvered toward the windshield and slid out. Some coolant may splash out, so have a towel handy.
  7. Replace the heater core with a new one by sliding it into place and securing the mounting bolts.
  8. Reconnect the heater core's hoses, turn the radiator's drain plug clockwise to close it, then refill the coolant system with a 50/50 percent mix of coolant and water.
  9. Reconnect the dashboard to the firewall, then replace the front dash panel and fasten its instrument cluster screw and bottom bolts.
  10. Crank up the truck and add coolant until the heater core is filled and blowing hot air.
  11. Replace the radiator cap.
The Jimmy uses a coolant-heated radiator core mounted in the dashboard to provide heated air into the passenger compartment. This heater core can become clogged and leak, as it is usually the lowest point in the coolant system and debris settles into it. Replacement of the heater core will take the average of about two hours to complete. Good luck

They are a pain, but you should be able to just take the bolt out on lower right side of the dash. Then you can pull the dash out enough to sneak the core out. It's been a while since I've done one those but, it is possible. It seems to me that you have to remove the glove box and remove the computer, or PCM, which sits on top of the heater to gain access to all the bolts.

How to replace a heater core in a 2009 dodge journey


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.

Does the 96 grand am have trap door for heater core with out taken the dash out


No trap door.

  • Drain the coolant
  • Remove the center console, the glove box, and the panels under the dashboard.
  • The connections to the hoses are in the engine compartment right at the firewall . The heater hose connection is difficult to get to. You may need to jack up the car and work on the hoses from underneath.

Need diagram for replacing heater core



    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

How do you repair a heater core in a1998 gmc jimmy


You replace them, generally requires getting up underneath the dashboard and sometimes removing the dashboard. You can try one of those radiator leak repair goops which are supposed to fix leaks, but I have yet to see one actually work. You dump these into a warm radiator, they glop around the leak and seal it, according to the packaging. Any car parts store will have a host of these sitting on the shelf.

If the core is leaking you can just disconnect the heater hoses which connect to it and put a piece of tubing between them to maintain flow. About half the Jeeps I have ever seen have this method of repair, but it tends to be a bit cold in the winter.

How do I change out a heater core on a 1997 GMC 1500 Pickup truck


you need to remove the glove box disconect the heater hoses look behind the glove box some heater boxes are two pieces and you can remove the heater half some you need to remove the whole piece if that is the case let a garage do it because they need to disconect the a/c so it needs to be evacuated and recharged if it is a two piece box just remove the bolts that hold the heater core under the dash and pull the box strait back good luck
