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.

Heater in 1995 Bronco is blowing cold air....What could be causing this?


If the heater is blowing cold air and the car is overheating, it is likely that the problem is related to the engine cooling system as well. The following are some issues that may be causing the heater to blow cold air:
  • Low coolant levels
  • A plugged/clogged heater core
  • A faulty thermostat (thermostat that is stuck)
  • Broken blower and/or blower motor
  • Heater core bypass hoses that have leaks
  • Heater core bypass hoses that are worn
If your car is overheating and/or your heater is not working, it should be inspected and diagnosed as soon as possible.

When i pour water in my radiator it just runs out under the dashboard underneath the car


Your heater core is leaking. It's under the dash and looks like a small radiator. Your heater motor fan blows through this to create heat inside your car. There are 2 heater hoses that run through the firewall to the core under that dash. If it were mine, I would go to a parts store and get an adapter so I could bypass the core by hooking the 2 heater hoses together. You will not have any heat in the car then, but at least you can drive it until you decide to fix it yourself( I'm pretty handy, but would not replace most heater cores myself as the can be very difficult to get to ) or get the best local price locally to have it done.

1998 Ford Taurus, heater won't blow hot air through any vent including defrost, coolant level is okay, no heat no matter how long car is run, car doesn't overheat, can't get warm air even if run at air...


common problem is the water resivor cracks up at the bottom... it appears that your water level is fine because the car doesnt over heat but i am willing to bet that resivor doesnt have water to the top. The radiator will hold just enough water to keep it cool. I replaced mine 3 times the sulution is doing to sound weird but go to the junk yard and get one off a murcury sable. dont know why but the sables res doesnt crack like that

How do you change heater core on a 1998 ford taurus?


this quite a job. you have to remove the dash. you have to lower the steering column, have to let the freon out of the system. its a 6 to 8 hr job at a shop. if you have no experience i would not mess with it. if water is leaking into you car there ia a way to bypass the heater core, where the two heater hoses come to gether at the engine, you can loop them . otherwise you can get a chiton manual or haynes that might help you replace the core.

I need to replace the heater core in my 1986 Ford Bronco 2. Are there instructions on line on how to do this?


under the dash on the pass side there is a large black plastic box. take out the 6 screws and pull off the cover. there is a wire attached to the top that controls a flap, that just lifts off. under the hood loosen and remove the 2 host clamps right at the firewall area. Push the metal tubes in to the firewall. Then reach back in from under the dash and pull out the old core. put the new one in reverse order.

Still very low heater output after changing thermostat, water pump. Blend door ok. car does not run hot. takes a long time for temp gauge to read from cold


These Tauruses had a problem with the heater cores plugging up, blowing out the head gaskets and no heat issues. Ford issued a TSB#98B26 (Tech Service Bulletin) to modify water pump and install a heater hose bypass tube. I would start by completely flushing the system with a good flush. Then reverse flushing the heater core. Refill the system and add a good additive. Also you can install the heater bypass tube as described in the TSB. The last one I did ran around $90 and 2 hours labor. Hope this helps you out.......
