No lie, it is a bit involved as it is buried deep in the dash, several pieces of the interior need to come out first. Here we go, I'll try to keep it as condensed as possible...It can help also if you have the wheels straight before you begin 1) disconnect the negative battery cable, wait a minute or two (precaution preventing airbag deploy) 2) drain the cooling system and disconnect the hoses from the inlet/outlet tubes of the core 3) plug the heater core tubes 4) remove the nuts that hold the left side of the plenum to the firewall (there should be three of them, under the wiper motor) 5) Remove one nut on upper left corner 6) disconnect the two vacuum lines and push them through to the passenger compartment 7) Take off the instrument panel trim moldings and the panel insulators 8) Remove the upper and lower steering column covers and disconnect the gearshift lever cable from the gearshift lever 9) Remove the steering column support brace, remove the bolts holding the steering column to the instrument panel and lower the steering column as far as it will go, and support it 10) Open the glove box, on the left side remove the bolts holding the instrument panel to the dash brace 11) Remove the left and right side cowl trim panels, remove the bolts on each side holding the instrument panel 12) Remove defroster grille 13) support the instrument panel and remove the instrument panel to cowl retaining screws 14) pull the instrument panel back as far as you can without disconnecting any wiring 15) remove the cross body brace 16) disconnect the wiring harness for the temperature blend/door actuator and disconnect the temperature control sensor tube from the evaporator case connector 17) disconnect the vacuum harness from the multiple vacuum connector (near the floor distribution duct) 18) Disconnect the vacuum hose from the outside/recirculating door vacuum motor 19) Remove the floor distribution duct 20) Remove the nuts along bottom edge of plenum 21) remove the plenum ensuring that all parts clear the dash panel (no snags or impromptu disconnects) 22) Once you have the assembly out, remove the screws holding the heater core cover and remove the core
In a nutshell, there it is. unfortunately, I do not know an easier way. This part is buried in there, not all cars are like this, but on the crown vic, it is.

How to remove the heater core in 1998 crown vic?


The heater core is under the dash on the right side, behind the glove box and the fan, and it is a bear to get out. Why do you have to remove it??? Also it is not like the old days, this one has the ac unit stuffed in there with it, all the heater lines on the engine side need to be removed, and possibly the ac lines.

How do i get to my heater core 1995 ford crown vic


Your heater core is located behind the dash. You need to remove the dashboard and your heater core will be located on the passenger side along the firewall. It will look like a small radiator. Get yourself a haynes manual for good step by step instructions and pictures to remove your dash.

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.

Remove heater core 1998 crown victoria


You dont need to remove all of those thing to do that. Working on the passenger side, remove the globe box and then the air bag, you are gonna see the bolts there. Now yo can see the black box behind the globe box? you have to remove the screws, some from the inside and some from the ouside (very hard to reach, under the box of the AC box outside).
Lifth the black box of the heater core and change it!!!
