I need a diagram of where the heater core is in the engine and the easiest way to replace the heater core.


Heater core replacement is delicate and it is very easy to damage hard to get parts, including the core itself. This job may be best for a shop to handle. The heater core is located in the heater box, follow the heater hoses from the engine to the passenger side firewall area...

Replace heater core


    A heater core transfers heat from a 1994 Ford Ranger's engine to the passenger compartment by running hot radiator coolant through a serpentine of tubing. Air blows past the hot fins of the heater core and into the truck cab.

    The hoses running to and from the heater core must be removed from the engine compartment, but the core itself is accessed from inside the passenger compartment, on the driver's side next to the center console.

    1. Turn off the engine, open the hood and remove the battery cable from the negative terminal. Make sure the engine is cool.

    2. Attach a 3/8-inch interior diameter hose to the drain outlet on the bottom rear corner of the radiator on the driver's side, and place the bottom end in a resealable plastic container. Turn the drain valve (located above the drain outlet) counterclockwise with a pair of pliers. Drain the engine coolant into the resealable container, then close the valve by turning it clockwise. Remove the hose from the outlet.

    3. Loosen the hose clamps on the radiator hoses where they attach to the heater core on the firewall. Remove the hoses.

    4. Unscrew the screws holding the underdash cover in place on the driver's side of the passenger compartment. Remove the underdash cover.

    5. Unscrew the four screws on the cylindrical heater core access cover and remove it. Remove the heater core by pulling it down and toward the rear of the vehicle. Replace the unit with a new heater core.

    6. Reinstall the heater core access cover and screw in the retaining screws. Replace the underdash cover and screw it into place.

    7. Replace the radiator hoses on the heater core in the engine compartment. Tighten the hose clamps. Add coolant until the level is between the minimum and maximum marks on the reservoir.

    8. Replace the battery cable and start the engine. Check the system for leaks.

How do you bypass the heater core on a 1998 Ford Bronco 2?


Disconnect both hoses from the core and one of them also from the engine. Hook the other one back to where you took one off, making a loop. The picture below is not a bronco, but gives you the idea.
By the way, your core is easy to replace. It almost pops right out from under the dash. I ahve included picture below.

Remove and replace heater core procedures:

  1. Disconnect the heater hoses from the heater core tubes and plug hoses.
  2. In the passenger compartment, remove the five screws attaching the heater core access cover to the plenum assembly and remove the access cover.
  3. Pull the heater core rearward and down, removing it from the plenum assembly.

To install:

  1. Position the heater core and seal in the plenum assembly.
  2. Install the heater core access cover to the plenum assembly and secure with five screws.
  3. Install the heater hoses to the heater core tubes at the dash panel in the engine compartment. Do not over-tighten hose clamps.
  4. Check the coolant level and add coolant as required. Connect the negative battery cable.
  5. Start the engine and check the system for coolant leaks.

Why does heater smell sweet


Hi yu heater smelling sweet is not a good thing. There is an engine coolant leak probably in the heater core and the smell your noticing is aspirated ainti-freeze. Check your engine coolant. It should be slowly lowering. The only fix is to have the heater core replaced. You can for the moment bypass the heater core by looing the hoses together with a nipple on the engine side of the firewall but you will have no heat or heated defrosting abilities until you replace the heater core.

Thanks for choosing FixYa.

Water under dash board 1983 buick skylark


Your heater core needs to be replaced. The heater core is like a mini radiator, providing heat for the interior by coolant circulating from the engine, into the heater core, and back to the engine again. Like a radiator, a heater core can spring a leak, especially w/ age as a factor. This results in the leak inside the car, which also causes the 'smoke' you see, which is actually vapor form of coolant.
