Remove the screws and see what it is.... some vehicles are horrid to change the heater core to the point where you have to remove the dash board to do it.
as far as cutting it open and replacing it that way... well it is your truck so if you choose to repair it that way then that is the way you do it.
To locate roughly where the heater core is... open the hood and locate the two heater hoses going to it on the firewall.

How to replace a heater core in a 2009 dodge journey


It will require several hours of labor just to get into the heater core. Its not so much the heater core replacement, its taking most if not all of the panels underneath the passenger side underneath the dashboard. Dpending on your car model, it may also require you to remove the glove box just to have access to the heater core.

In rare cases you have to remove the whole top dash board but most cars in general only require to remove panels underneath the dashboard on the passenger side. It's tricky to remove the heater core because it is well hidden behind many panels, a whole lot of screws to remove. Then you have to remove or cut the heater hoses in front of the engine compartment as those hoses are attached to the heater core.

I just replace the heater core in my old buick and it took some effort to undo all those panels and hoses and screws but i finally got it all done and heater works perfect. That repair at a automovtive repair shop would of cost me 350 to 400 dollars. I just spent 35.00 bucks for the heater core and another 12.00 bucks for new heater hoses and that was it, that and the intense labor involved to remove the old heater core. But i saved a huge bundle by doing it by my self, good luck.

How do I change my heater core in my 1996 ford ranger


The heater core is located in the heater box, under the passenger side of the dash. Most FORD heater boxes are snap-clipped together, and if you remove the rear panel from the heater box, you will see the heater core...it looks like a smaller radiator...twist the heater hose off of the heater core (x2) from the engine side and gently remove the heater core from under the dash. When replacing the new heater core, be very careful re-installing new hoses to the core...it is a fragile thin metal that can leak almost instantly if tweaked too roughly...replace all parts in reverse order of removal.

I HAVE A 1996 CHEVY P/U AD I NEED TO REPLACE THE HEATER CORE IS IT HARD TO DO ?


there should be an access panel under the glove box for this year model. if the access panel is not there then you have to remove the dash to get the heater core out. GM made the switch with the access panel to no panel somewhere close to this time depending on the build date of the truck.

Looking for heater core replacement instructions for 1997 Ford F250 Heavy Duty, 5.8L V-8 w/ A/C. Please tell me I don't have to remove the dash! Thanks!


Drain your coolant low enough that it wont make a mess when you remove the the hose from the heater core under the hood, then remove the glove box door, looking at the heater box thru the glove box door opening remove seven (7) screws on the heater box, remove the panel and then remove the heater core, opposite to reinstall.

Heater don`t blow hot air


most likely cause would be your heater core instructions below!


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.
f74-01.gif The heater housing is disassembled to get to the heater core.
Heater Core
  • 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.

I have a 1996 grand prix se I believe that my heater core is leaking how hard is it to change it in this vehicle


It's a big job. The heater core is accessed from inside the car under the dash. If your car has a center console, it must be removed, along with the glove box and the under dash covers. Then you'll see the actual heater box. Removing the box will show you the core, but you'll need to go under the hood to disconnect the heater hoses before you can remove it. Obviously, you need to drain the cooling system first.
Also note, when you replace the core and put the heater box back in, the box has to be sealed for proper operation. In some cases, either RTV sealant can be used, or foam tape.

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.
