it is located under the dashboard against the firewall of the passenger seat. i recomend buying a repair manual from your local auto parts store before attempting as it requires draining, flushing, refilling and bleeding the cooling system as well as removing many other componets like the entire dashboard and thermostat

SOURCE: bad heater core

look undre the passenger side dash and you will see a black box. Look closely and you will see screws in it around the edges. remove all the screws then remove the cover,there is the heater core, held in by 1 screw that is kinda hard to see. next look under the hood on the passenger side firewall right in front of the dash, you will see 2 hoses with clamps on them. loosen the clamps and remove the hoses. you may want to drain the radiator first but I never do

SOURCE: How to replace a heater core in a 1994 chevy 1500

As with all vehicles it seems the first part that they build around is the heater core. It is under the dash above the floor housed in a black plastic sealed box. Sealed with goop. Locate that box and start removing everything around it that is peventing taking the cover off. Of course disconnect the heater hoses under the hood a thefirewall.

Warning it is never as easy as it sounds.

SOURCE: how do i change a heater core on a 1995 chevy

Changing the heater core is a simple process. Getting to the core to actually change it can be daunting if you have never changed one before on a corsica. All cars are different in that you have to remove enough dash parts to actually allow you to get to the core and they are all different. This is why labor charges are so high for changing a $50 part.I have never changed one on a Corsica myself. If you do this yourself, take digital photos as your go along so you will be able to put everything back in the correct order. I know this is not really the answer you want, but you are probably not going to get detailed instructions on how to do it, other than just remove enough parts to get to the heater core. Go slow and figure out how the parts come off and what parts to remove. Not an easy repair even if you have done it before. Good luck.

Remove heater core on corsica


Heater core on a corsica is tricky. It's under the dash in the middle. First disconnect hoses under the hood. Then remove plastic panel 8mm bolts under dash. Remove bolts holding the clips that hold the heater core in place. To remove the heater core you must peel back the carpet or you will not be able to get it out and a new one in. Once it's out, put new one in the opposite way. The carpet has to be peeled back and heater core manouvered to get it in and out. Good luck

Coolent leaking from rear of engine can not see from where. When I stopped the car the fluid kept coming out. Engine overheated, I checked the front hoses they are dry and no leak from the radiator. What...


You could have a leak coming from the intake or even the heads. Before digging into those difficult items, I'd check all of your freeze plugs for damage/wear/rust/leaks.
