If this is the original heater core it may be stuck to the firewall and you will have to pry it off. Make sure that there are no other bolt holding it!!!

When engine is cold of course, drain your coolant, Disconnect the negative battery cable, remove the heater hoses at firewall, disconnect the operating cables from the heater vent housing under dash, and disconnect the defroster duct. Now under the hood again, disconnect the wire from the blower motor, and remove the nuts that hold the heater housing to the firewall. Then under dash, remove the heater housing by tilting it downwards to clear the defroster duct, and back towards passenger seat. Remove the housing cover from the firewall side of the housing and remove the heater core. Clean the housing and install new heater core and assemble in the reverse of dis-assembly. Don't forget to put coolant back in after it is back together!

How do you remove heater core in 1962 rambler classic?

The heater core is contained in the plastic/fiberglass housing assembly fastened to the engine side of the firewall. Unplug the wires from the fan motor on the firewall and remove the Phillips screws fastening the plastic housing to the firewall. Remove the heater hoses from the core inlet and outlet and tuck them out of the way. You may have to reposition some brake lines and cut a couple of wiring harness plastic ties. You may also have to remove the lines from the fuel pump to the carburetor if they interfere. You may need to temporarily remove the rocker arm cover. Pull the plastic housing away from the firewall and you will see the heater core inside the housing.

The heatercore is located on the passenger side under the dash. It is located on the left side of the blower fan. Remove the heater core housing which consists of 5-6 screws.

Where is the heater fan on a 1996 Blazer and how do you remove it?

The heater blower/motor seems to be incased in a plastic housing on the passenger side firewall , right behind the on-board computer. There are 3 screws holding the computer in place and need to be removed, to access the heater/blower motor behind it. The plastic casing needs to be cut with a utility knife to access the blower itself.


How do you cange the heater core on a 1983 Chevy Malibu?

It's really not that difficult. Under the hood on the passenger side firewall you'll see the A/C and heater core housing. There will be several screws holding the top of this housing on. Take them out and remove the top being careful not to crack or damage it. You should now be able to see the heater core. It will have two hoses running to it. Remove them. It's been a while since I've done one but there's also a bracket holding the heater core in if I remember correctly. Remove it. Now you should be able to lift the core out. Installation is the reversal.


How do you change a heating core on a 1996 Chevy Corsica?

1) Raise the front end of car. Don't be stupid, use ramps or jackstands. 2.) Remove the hoses, they're about in the middle of the car on the firewall slightly to the driver's side of the exhaust pipe. 3.) Remove the ductwork housing below the heater core housing. There are 2 duct tubes (1 driver side, 1 passenger side) that you pull off, then remove the screw (7mm) holding the ductwork housing to the heater core housing. After you remove the screw, you'll have to push the housing towards the front of the car to remove from the ducts under the carpet on the hump, then pull the carpet back and move the housing toward the passenger side. 4.) Remove the screws holding the heater core housing, there's one way in the back slightly to the driver's side of center that's a little difficult to get at. 5.) Pull housing straight back (the overflow tube keeps you from pulling it out in any other direction. 6.) Remove screw holding housing halves together and open. 7.) Remove screws holding heater core clamps to housing. Installation is the reverse. The original plastic tubes coming through the firewall tend to crack, break during removal, the tubes on the new heater cores are metal and come attached to the new core. The replacement heater cores are more universal and the tubes are built to rotate at the point they enter into the heater core tank so you can adjust it to fit your car. When I changed mine I had the dash out of the car, but I don't think it's necessary. It did make it an easier job though. Good luck.

How do you get to the heater core on a 1985 Buick Regal?

To get to the heater core, first remove all electrical connectors from heather housing under the hood. Next remove the chrome trim piece at the bottom of the windshield. Remove the two aluminum brackets mounted to the firewall used to hold the chrome trim piece with the speed nuts. Then remove the top screen portion of the heater housing, followed by all the bolts/screws for the top half of the housing. Using a large flat screwdriver or prybar, separate the upper half from the lower half of the housing, and from the firewall. Note, the wiper arm and bracket may need to be moved to gain access to certain screws/bolts, and for clearance when removing the upper half of the heater housing. The heator core will now be exposed. Remove the screw securing the ground clip and bracket holding the heater core down. remove the two heater lines attached to the heater core, and pull the heater core up and out of it's place. Before installing a new heater core, clean out any coolant and/or other debris from the heater housing. Installation is same as removal in reverse order, except the upper and lower halfs of the heater housing need to be sealed upon reassembly. Fairly easy job, just takes a bit of patience.

How do you replace a heater core in a 1998 ford F800?

Really long bolts go through the heater core/blower motor housing into the cab. You have to go through the dash and undo the nuts and the housing will come off the front of the firewall in the engine bay. Once the housing's removed, it has a cover/bracket that has to be unscrewed around the perimeter of the housing to release the heater core.
