Heater Core Replacement


Cars these days are put together in a modular way which tends to make things difficult for subsequent repairs and replacements. The first thing to be fitted in the bare body shell would be the heating and ventilation box, pipes and cables and then the complete dash probably with steering column already attached.

You didn't mention the make and model of your car and I doubt that would help me if you did as you are probably over the water with the steering wheel on the wrong side.
As a general rule in order to access the heater matrix the car needs to be taken back to the stage in production when it was originally fitted. Sometimes the complete heater unit must be removed and sometimes once there is access there is a helpful letter box slot to slid the matrix out.
In these cases access and replacement is usually more difficult if the car was designed as a right-hand drive but is in fact a left drive and vice-verso.

It isn't the sort of job I would like to tackle without a repair manual to hand, especially in winter when plastic is very brittle and unforgiving.

Needing to remove the entire dash along with the steering column is entirely realistic and unless you can see a helpful letterbox I advise you to do that which will in the long run save your knuckles and your temper and maybe your marriage.

Good luck!

1998 Chevy Blazer heater core installation


Your job will be a long one, but not the worst one out there by far. You will need to unhook the battery, remove all of the lower trim from the driver and passenger sides under the dash. Remove the nuts that hold the steering column to the bottom of the dash and let is rest on the drivers seat. Remove the kick panel trim from both the drivers and passenger side foot well. There are 2 bolts on each the drivers and passenger side that hold the sides of the dash board to the vehicle, then there are I believe 6 bolts along the front edge of the dash along the windshield that need to be removed. This should let the dash be tilted back away from the windshield and rest atop the steering column. There will be an access door in the top of the heater box that will allow removal and replacement of the new heater core. You will still need to unhook the hoses under the hood, and you might need to unplug, or remove some ground wires hear and there, just make sure you take note of what you have to unplug or remove and make sure you put everything back like it was before you started.

Heater core


This is a job best left to a pro. The heater core is in the HVAC box, under the dash. You need to COMPLETELY disassemble the dash to access the HVAC box. Usually you need to remove the front seats, drop the steering column and remove the center console [if it has one] for access to remove the dash. You also have to drain the radiator & A/C system. Reassembly will require access to an A/C vacuum pump and gauge/hose set.
This job will take a pro about 8 hours to do. Sorry, but most Ford cars are a real bit*h for the amateur mechanic to do. Once you have everything apart, you can acually see the rear side of the firewall!

Needing a short cut to replacing the heater core 97 twn car


You can start by not completely removing the dash and most of the components of the dash can stay connected, you will pull dash out a little and then pull away from pass/side and tie up out the way, instead of dissconecting all the dash components like radio heater controls and etc, the steering column can be removed its not hard, unplug connector and the shaft and remove the steering column as a whole, hope this helps.

Can the heater core on a 1985 ltd crown victoria be taken out on the engine side of the firewall? Do you have a set of step by step instructions to complete this task I am very mechanicly inclined


No Sir it can not. The heater core on those vehicles must come out into the passenger compartment and book time is 12 to 14 hours. I can tell you a professional system I always use that has some good shortcuts in it. The book calls for removing the steering column and dash. My short cuts avoid that. You can leave the column and dash partially hanging and still complete the job. I will be telling you this process from memory. First with the engine cold drain the coolant from the heater core by removing only the 2 hoses to the heater core under the hood. Now flush water thru the core with a garden hose. ( This is so you do not spill coolant inside the car) There is a stud with a nut (maybe 2 studs w/nut)on it between these hoses remove this nut as it holds the top of the heater box to the firewall. Now go inside the car and remove the two lower kick panels made of plastic by the drivers and passengers outer foot. Behind the drivers panel there is a large nut holding the dash to the window post where the hinges are attached to. Loosen this nut almost all the way off. On the other side remove the large nut completely and the small nut also. Pry the plastic cover up that covers the dash right under the windshield and there are several screws to remove there. This loosens the dash on the left side and allows you to pull the right side out enough to spin the heater box out and to the floor. Now remove the plastic covering under the steering column and the metal plate behind it. This part is important > Be sure to loosen the adjuster on the transmission indicator cable and remove the cable from the steering column before going further. This is the small black cable that moves the dash indicatro from park to drive...ect. if you do not remove this cable prior to dropping the column you will break the plastic that holds the cable to the instrument cluster. Now remove the 2 bolts holding the upper part of the column to the dash. Now there is a floor vent in the center made of plastic that must come out. There is a screw on the left side and a plastic pin button you pull out. Pull out the ashtray and there is a small screw behind it holding this vent also. You will have to pull the vent to the laft and out. I make a small **** in the plastic vent this attaches to under the carpet to send air to the rear floor so I can pull it out and replace it easier. Ok, now remove the 2 lower bolts on the steering column and let it rest on the seat. Go over to the right side and remove the two nuts under the heater box and now the heater box is free from the dash. Now pull the right side of the dash out and up to access the heater box. You will see 4 screws and possibally a bracket with a switch mounted to two of these screws that we need to remove to access the heater core. 4 screws hold the core inside the heater box. Pull the core out and install the new one in the box. You may have to prop up the right side of the dash to get enough clearance. Careful to force the dash and not the new core to put the box back in place. Aklways put the top stud thru the firewall first or you will not get in in. If you attach the bottom studs first the top will not line up. Now just reverse the procedure to reinstall and you have just completed one of the hardest jobs in auto repair.

Heater core


18901fc.gifHere is an exploded view of the heating/air conditioning blower box. This contraption is located on the passengerside under the dash. I've changed heater cores on other cars but never worked on a caravan so not sure how difficult it'll be. You may need to remove a few cover panels to access this and the heater core #22 is located behind the distribution box #6 containing parts 7-18 and hopefully comes off as a unit. I wouldn't want to put it back together just looking at the pic. You may just need to remove the heater tube cover #4 to access the connections and slide out the core.....NAH couldn't be that simple!!! Hope this was of some help. Good luck.
