SOURCE: 1994 buick lesabre heater core removal

The heater core is located under the dash, in the center. 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. You must first drain the radiator then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that go thru the center of the firewall. Remove the screws that hold on the cover to the heater core. Then you should be able to get the old one out. There might be a couple of other minor steps but I'm sure you can figure them out. For re-installation just go in reverse order to put it all back together.

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

You have to remove the entire front of the heater case to change thecore. This usually looks a lot easier in print than it actually IS.Theinstructions say to remove the lower part of the dash for access; usually youdon't have to remove the entire dash for this type of service, althoughsometimes it makes things easier if you loosen and remove any components notmentioned in the procedure that are in your way.
This kind of repair can be frustrating, as it involves working in tightplaces and with 1/4 drive extensions and universal sockets to get all thefasteners out, but it IS possible.Here is what I have for the factoryprocedure. I don't know of any shortcuts to make the process easier; if you can'tget it off, perhaps removing the dash completely for more room would be aviable option...

Heater not heating very good


If the coolant level is full and the water pump is circulating the coolant through the system adequately then the most like cause is the heater core has become clogged. The heater core can be flushed or replaced to fix the issue.

My 1988 Buick LeSabre blows coolant steam into the passenger compartment when I turn on the heat and the fan. Also there is dripping coolant coming from the under the dashboard onto the floormats. Could...


Yes! the heater core is bad/leaking. it sits inside the heater box under the dash. it is a fairly big job to replace and should be done by someone who is knowlegeable and expierenced in the replacement of them. the ac system ahs to be drained/evacuated if still charged and the heater box opened for removal of the heater core. Sorry for the bad news but you are correct in your diagnosis.
I hope you find or have someone who wil take care of you on the price. This can be rather expensive to have repaired. Ballpark of 350-500 depending on labor per hour costs at a professional shop.
Good luck , Scott

I put stop leak in radiator and now the car blows cold air vs hot air when running the heater. why?


The stop leak have restricted the coolant flow to your heater core. You can try flushing out the Stop leak with Preston Radiator flush or replace the heater core. Once Cooling system flushed out, replace thermostat, radiator cap and repair coolant leak. Good luck and hope this helps, and Note: Common Black kitchen Pepper does great as a radiator stop leak without leaving any residue and can be cleaned out of the system with water and not coolant flush. Two table spoon is more then enough to stop a small leak. Good luck and keep me posted friend.
