Not an easy job - steering column needs to drop down - bolts under dash - bolt on each side above hood release and glove box behind kick pads - top of dash should have 4 screws going towards windshield - with glove box - radio - temp control -gauge cluster out - any other brackets and bolts should be seen - heater core box will have to come out as unit - freon lines to be disconnected - a/c system will have press. in lines

Where is heater core located on 2008 Chevy Silverado 1500 4.3L

Most of the time the heater core is in the worst place possible. Should be right in the center of the dash at floor level behind everything. May not be exact but close.

How to take heater core out of 2000 Old's intrigue

You'll need a manual. You can get a ''Haynes'' repair manual at an auto parts store and/or on the internet for about $25 dollars. If not, you can get a factory manual, but it will cost you dearly. The job usually involves taking apart the dashboard. How far _into_ the dashboard you have to go will be explained by the manual. Sometimes, you get lucky and only the glove compartment has to be removed. Other times (especially with air conditioning in the way), you have to take the whole dashboard apart. // Yes, you'd think they would make it as easy as ''open the hood, remove the heater core'', but unfortunately, going all the way back to the 70's, they are behind the dashboard... unless it's an old truck. The heater core in my '65 Chevy Pickup is a half hour job.... Sorry :-(

Replace heater core

    • 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.

Replace heater core

If you remove all connections to the dashboard: 3 big ones on the right, one big connector held together with screw in the middle near the steering column, vacuum hose connection, connector behind radio, and antenna connection, you should be able to lift the entire dashboard out off of the pivot pins. You will then have access to the plastic heater core cover. Removing the glove box gets you comes out with the entire dashboard assembly

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!

How do you instile a new heater core and remove the old one.

Things You'll Need:
  1. Step 1 Remove the dashboard. The heater core in S10s is behind the main dashboard, and it must be removed to access the core. The front dash panel can be removed by unbolting several screws at the bottom of the panel, then pulling the panel away from the dash. Once this front panel is off, the primary dash can be unbolted from the firewall with four large bolts below the windshield. Several accessories may need to be taken out to unbolt the dash from the firewall, such as the radio or 4WD switches.
  2. Step 2 Drain the coolant from the core. There is a drain plug at the bottom right of the primary radiator that will empty the coolant system when unscrewed. Some residual coolant might remain in the core, but will come out when the core is taken out later.
  3. Step 3 Uncouple the core from the coolant lines. These hoses are directly behind the oil filler tube, and will come loose when squeezed with pliers. They are of different sizes, and it won't be necessary to mark them for later re-attachment.
  4. Step 4 Unbolt the core from its mounts behind the removed dash panel. Several bolts might be difficult to reach, but once free from the mounts, the core assembly slides up and out towards the interior of the truck. Lay a towel down when removing the core, as come coolant might splash out.
  5. Step 5 Insert the new heater core and bolt it into the mounts. The openings will fit into the holes provided in the firewall.
  6. Step 6 Reconnect the heater core hoses, and re-attach the dashboard and front panel.
  7. Step 7 Fill the coolant system with a 50/50 mix of antifreeze and water. Tighten the drain plug on the radiator, then fill it. Crank the truck up with the heater system on its maximum setting, and continue to pour coolant into the radiator until it will not take in any more.

Drain the coolant. Remove the dashboard first, then a bunch of air ducts, then the heater core cover. Remove the heater hoses in the rear of the motor, and finally the heater core.

How to replace heater core on a 1989 Chev. 1500 (350)

Start by draining the coolant, disconnect dash board wiring harness from pcm behind kick panels, disconnect eye shaft, unbolt dashboard and remove dash. (Remember to tape steering wheel in place as it might have a clock spring). You might have to remove some trim panel on top of dash or cluster from dashboard to gain access to retaing bolts, disconnect heater hoses from heater core in engine compartment and remove heater core, reverse install.

Remove air duct bezels for defrost.
Remove all screws.
Remove Glove compartment entirely

Remove all support brackets underneath
Remove all electrical connections notice where they go if not sure color code them with tape.

Dashboard should lift up once all screws are remove and you can pull towards you.
Lower the position of the tilt wheel if available.
Remove blower motor for heater if necessary,
Be careful with the connector for the heater door. You can remove the heater door carefully, don't mess up the felt
disconnect heater hoses remove heater core.
When connecting heater hoses, make sure you connect them the same way again, and apply sealant to the hoses before tightenting clamps. You sure like hell don't want a leak after you mount everything back.

I ran the heater while I had the dash board off just to make sure there were no leaks. Reverse procedures to install at your discrection. Suggest you follow all steps in reverse so you don't end up with screws you can't figure out where they go.

Its about a two day job if you do it alone. They charge 900 at the dealer for doing this. Can't understand why in the world FORD just doesnt make an access system so you can remove the core without removing the dash board. Yes I do...........MONEY! No wonder American car mfg. are in such a pitiful state the the foreign car market is kicking ***. American cars to change the fuel pump you have to drop the tank. Japanese cars to change the fuel pump you go to the hatch over the tank remove the hatch and remove the pump. Get the picture!!!!!! Good Luck.
