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.

88 bronco II, heater hose going to water is cold, and my heater blows cold air, is my water pump going bad? the return heater hose is warm, it was heating once in awhile now it don't heat at all just cold...


I would try flushing heater core to see if it's plugged. I don't think it's waterpump, your rig would be overheating if it was. Leaking is most common waterpump failure.

Heater Core Bad


get a new heater core, get a repair manual on ebay, follow the instructions and replace the core. on a car that old you will not have to fart around with a dash airbag and should be a straight forward job.

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.

Remove and replace heater core 86 f150


This is not a terribly complicated job -- it's mostly bolts, hoses and clamps. It can be messy depending on how much coolant there is in it.

Access to it may be the biggest headache depending on whether it's under the hood or under the dashboard.

Doing this job for the first time will probably take about 4 hours.

No heat or defrost


Thermostat is not on the radiator. It is in a housing on the intake manifold at the engine end of the top radiator hose.Heater controls on that truck may be vacuum controlled or cable controlled You need to check and make sure that the heater lines are open and water is flowing through them.
