SOURCE: Where is the heater core hose in my 2000 ford expedition?

check closer to just underneath the firewall--it could be a smaller problem than a heater core--Ford 4.6--5.4 engines have a tube just underneath the intake manifold that the rubber hose goes bad and it will leak towards the back of the engine.Lets hope so-what i hear its very expensive to change a heater core in an Expedition.

SOURCE: temp guage showing hot, not getting any heat for 1992 Mercury Cap

If the hoses to and from the heater core are hot , and you say the heater core is hot , then the only answer is that the air duct that flows into or out of the heater core plenum ( housing ) is not opening.
Heater control on dash borad inoperative.
Not sure about 92 capri , some cars have a cable linkage , some work on vacume motors.
Try to find a haynes manual for your car , they will walk you through almost every step of anything you may ever want to do to your car.

You seem to know what you are doing , but I gotta ask ........the heater core you felt was up behind the dash inside the passenger compartment of the car right ?

SOURCE: My heater is blowing cold air in my 2002 mercury

Remove the center console and on the drivers side toward the bottom of the heater box will be a small electric blend motor. Replace this motor. New part should be about 90 usd. After the center console is out should be three small bolts holding it in.

How to remove the heater core on 94 mercury cougar


Removing the Old Core
  • Disconnect the Mercury Cougar's negative battery cable. Remove the center console from the interior. Disarm the car's air bag system and remove the bag's diagnostic monitor and bracket.

  • Take the heater outlet floor duct out of the car. Remove the screw holding the air transfer duct and push it into the outlet duct. Unscrew the screws retaining the outlet duct to the heater core cover and release the retaining tabs on each side to remove the duct.

  • Raise and support the Mercury Cougar, using multiple jackstands. Drain the engine coolant by removing the drain plug on the bottom of the radiator. Replace the drain plug after all the liquid flows into a clean container and disconnect the heater hoses from the core

  • Withdraw the black vacuum supply hose from the vacuum source (you can now lower the vehicle). Disconnect the same hose from the air conditioner's vacuum reservoir tank.

  • Detach the heater core cover that holds the core by releasing the retaining tabs and removing the clips. Remove the dash panel seal, vacuum hose and heater core bracket from the cover.

  • Remove the heater core from the cover and the case seal from the core

I would like to know how replace my heater core on a 2001 S10 chevy blazer


Instructions
    • 1Remove 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 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 it will come out when the core is taken out
    • 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 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 toward the interior of the truck. Lay a towel down when removing the core, as come coolant might splash out.
    • 5 Insert the new heater core and bolt it into the mounts. The openings will fit into the holes provided in the firewall.
    • 6 Reconnect the heater core hoses, and re-attach the dashboard and front panel.
    • 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.

How do i remove a heater core on a 2001 grand cherokee


The heater core on your 2001 Jeep Cherokee is responsible for providing heat in the cab of your vehicle. Overtime or due to driving conditions, the heater core can become plugged with dust or corrosion and stop working. If it is not working properly, the heater in your Jeep will not warm the interior and could cause the windows to fog over. To avoid this, if you start seeing signs that the core is not working properly, you can remove it yourself in about 2 or 3 hours and save yourself the expense of having someone else do it.

just follow these steps:
  • 1

    Detach the negative and positive battery cables from the battery of your 2001 Jeep Cherokee with an open end wrench and crescent wrench.

  • 2

    Remove the cap from off the radiator and also from the top of the coolant overflow tank on the passenger side of the Jeep. Locate the drain valve at the base of the radiator and place a drain pan on the ground, below the drain valve.

  • 3

    Open the drain valve on the radiator with an open end wrench and allow the coolant to drain into the pan completely. When it is finished, close the drain valve and remove the drain pan.

  • 4

    Unfasten the dash pad on the top of the dashboard by using a screwdriver to undo the screws holding it in place. Check the defroster vent and remove any screws holding the vent screen in place.

  • 5

    Remove the trim panel underneath the passenger side of the dashboard with a screwdriver and set it aside. Locate the plastic box that is sitting underneath the dashboard on the passenger side.

  • 6

    Undo all the screws that are holding the plastic box in place with a screwdriver and set the box off to the side. Locate the heater core that was sitting inside the plastic box.

  • 7

    Unscrew all the screws that are holding the heater core to the firewall with clamps underneath the dashboard. Remove the clamps from the heater core.

  • 8

    Lay a piece of plastic sheeting on the passenger side floorboard to cover the carpet from any coolant remaining in the heater core. Pull the heater core away from the firewall until you see the hoses attached to the inlet and outlet pipes on the unit.

  • 9

    Remove the water hoses from the pipes on the heater core by unscrewing the hose clamps with a screwdriver and sliding the hoses off the pipes.

  • 10

    Take the old heater core out of the Jeep Cherokee and dispose of the unit. Recycle the drained coolant by taking the drain pan with the fluid to your local recycling center or automotive supply.

    My cougar is overheating today sporadically, going from normal to high and back as I drove today. I don't see any signs of leakage or hissing in the engine compartment area, indicating a hose problem. ...


    sounds like your coolant level dropped enough to empty the heater core and your engine was not getting coolant up to the cylinder head, check the coolant immediatly and fill then idle in the driveway till fully warm and you should notice the leak

    Heater is blowing cold air,


    Check operation of heater coolant control valve, and it's associated remote control mechanism.
    Check that both inlet and return heater hose is equally warm, as this indicates coolant flow through the heater core.
    If no coolant flow:-
    Check cooling system is correctly filled, taking care to bleed off any air locks from the system as necessary (with heater coolant valve open);
    Check heater core is not blocked.

    Low Heat on 1999 Mercury Cougar


    I had the same problem with my 199 cougar 2.0 4 cyl.
    The problem was air in the cooling system.

    I had to bleed the air out of the system, and now the heat
    works much better.

    I put a flushing tee between the back of the thermostat and
    the heater core, and made sure that water flowed out of there.
    Then I disconnected the small hose from the top of the coolant
    resevoir, and poured water into it using a funnel until the coolant
    level started to rise in the coolant resevoir. Then started the car, left the radiator cap off, and let it come up to temperature (thermostat open)
    then over a period of about 5 minutes, periodically "goosed" the engine to clear any remaining air bubbles.

    The heat is MUCH better now.

    Ok you have a bad blower speed controller if you have power to the motor.
    It is located under the hood in the heater housing just below the heater core coolant hoses.
    You will have to drain coolant.
    Remove the nuts holding the Vapor Management valve and set it aside.
    Remove coolant hoses to heater core.
    Disconnect electrical connector to the blower speed controller,remove screws,pull it out of heater housing.
