How do I replace my heater core on a 1988 my Ford f250


Hello there, here are steps to help you through:
  • Disconnect the negative battery cable.
  • After making sure the engine is cool, drain the coolant from the radiator into a suitable container for recycling. It is always good practice to replace the coolant with fresh coolant after replacing the heater core. The old coolant will contain corrosives and contaminants that will accelerate deterioation of the new core if you reuse it.
  • Disconnect the heater hoses from the heater core connector pipes on the engine side of the firewall.
  • Working in the passenger compartment, remove the glove box for better access.
  • Still working in the passenger compartment, remove the seven screws that attach the heater core cover to the plenum assembly (the plenum assembly is the protective housing into which the heater core is mounted.)
  • Disconnect the vacuum source but leave the vacuum harness attached to the plenum cover.
  • Remove the plenum cover.
  • Remove the heater core from the plenum chamber.
  • Reverse the procedure to install the new heater core.
  • Make sure the radiator drain plug is closed, that the heater hoses are properly tightened.
  • Make sure the new coolant is properly mixed with an equal amount of clean water (distilled water recommended) to produce a 50/50 coolant/water mixture.
  • Fill the radiator with the proper type and amount of fresh 50/50 coolant..
  • Start the engine and check for leaks.
  • Check the coolant level after driving the first few miles and top off the coolant level (after engine cools).
Hope I could be of help. Best of luck

Where do the heater core hoses attach to engine on an 1988 f-250 with air


If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

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.

  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.

My crown victoria is leaking radiator water inside the car. mainly on the passenger side beneath the glove compartment. It smells really bad, and I can't find the leak. Is there any way to get detailed...


Yes, it's the cars heater core leaking. The heater core is like a mini radiator under the dash-coolant circulates through it from the engine to provide the heat. To change the heater core is a very labor intensive job. You really need to get a repair manual, or go online to 'alldata' diy repair where you can sign up for 1 year or more access to your Crown Vics repair info. Excellent source for diagrams and instructions. I believe one year is $16.95, good for ONE car info for a year.

Need to replace heater core in 1988 Ford Crown


i too replaced the heater core on my 1988 ford cv. the important point to rember is not to get overwhelmed. i ended up removing the whole dash, but not the stearingwheel. lable everything you remove....best to keep all parts seperated. mine looked like a nascar when i finaly got to the black plastic box where the core lives. i had to also remove some of the heating duct. once you open the box up, youll see the core. just sits in there. remove in and out hoses. very simple, but alot of work, thats why you must keep track of everything you remove. your engine coolant may be low, so add more when compleated. its been about 4 years now since i replaced mine.....i dont rember if the black box was rivited togeather or screwed togeather. if rivited, get a dremel tool with a grinder wheel, this will remove the rivites in good time. but the duct work was stapled togeather, i used 1/4 inch sheet metal screws to hook back up, works just fine.
