Remove glove box. remove black plastic cover under dash board on passenger side. unhook the two black rubber hoses under the hood leading to the passenger side firewall unbolt heater core install in reverse order
I own a 1994 LeSabre and the heater core on my car is located under the dash (in the center in a black plastic box). Remove some of the cosmetic dash pieces to access this black plastic box. First, you must drain the radiator of coolant, Then remove the two hoses. Next, the cover of this balck box can be removed by unscrewing the two screws Remove the screws and the heater core should now be accessable. Then you should be able to get the old one out.
no just the lower cover below the bottom of the dash board,the black plastic cover thats recessed back farther than the main dash,there are a lot of screws and turning and twisting to get this cover off,but you need not remove the whole dash to access the heater core
Well first, if your talking about the radiator hoses when you say the bottom hose is warm and the top is cold, that would suggest to me a stuck thermostat. If not, then the heater core is located inside the truck under the dash. You can follow the heater hoses under the hood to the firewall and that will tell you where, under the dash the core is located. It is kind of a big job, as all the under dash covers will need to come out as well as the glove box. The heater core is inside the heater box, a black plastic box that will also need to be removed. It is important to note that when you are reinstalling the heater box after you change the core, it must be completely sealed, either with RTV or two sided insulating tape.
It is very hard!! You actually are supposed to remove the whole dash!! I took a shortcut and just took the screws out of the plastic box under the dash where the heater core is,behind the console, next to the floorboard, and cut it across the back on the bottom. You then have to get under the car to remove this screw that is on the firewall between the 2 heater core hoses..then remove the hoses from the heater core on the firewall. Then you can get back inside the vehicle and it will pull out. When you replace, the cover that you cut, just put the screws back in and put some tape across where you cut the cover off. It saved me from having to take the whole dash out, and having to spend $300 to have a mechanic replace my heater core!!
Drain the coolant. Remove the dashboard first, then a bunch of air ducts, then the heater core cover. Remove the heater hoses in the rear of the motor, and finally the heater core.
Actually if your handy the heater core on this car is pretty easy.. passengers side under the dash... but here is a link to some sites that will probably help
from .... one of the wikki sites.. LOL cant remember which now
The heater core is located under the dash, in the center above the "hump". The container holding the core looks like a black plastic box. Remove the ash tray for easier access. You may have to also remove some other covers under the dash. First drain the radiator. Then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that are thru the center of the firewall. This has to be done from underneath the car while raised. I also had to unbolt a frame support to get to the hose clamps (I have big hands; you may be able to reach them without unbolting it). Remove the screws that hold on the cover to the heater core. You should be able to get the old one out now. Just go in reverse order to put it back together. also this link is very handy they have a pretty complete collection for MANY vehicles http://www.autozone.com/shopping/repairLanding.htm
